I’m selling my PARADIGMS!!

Even though I literally finished yesterday afternoon we listened to them all evening! The bass is controlled and realistic. The treble clear and bright. These are revealing while still being musical. I can tell what the producer thought of the performers by how they were mixed. These reward great vinyl pressings but don’t punish others. And, they can get up and boogie when asked.'

-Judith Rhodes 'The 10' Alnico drivers sound amazing. These sound almost too good to be true. It's a sound to behold.

'Being the music', is what it feels like listening.' -John Tann 'The Audio Nirvana 'Super 8 Alnico' drivers are by far the most natural, neutral, musical, and extended full range driver I've ever owned or heard. I don't say this lightly. I've owned the 'who's who' of both vintage and modern 8' full range drivers such as KLANGFILM, TELEFUNKEN, GOODMANS, JBL, FOSTEX, ALTEC 755s, and even $3K electromagnetic SUPRAVOX 215s.

In the category of more common audiophile speakers, I've owned some of the more famous studio monitors such as HARBETH, ATC 20SLs, and VERITY AUDIO Parsifals. I've also owned electrostatics such as QUAD ESL57s and ACOUSTAT 3s with the direct drive servo amps. I am a professional in the manufacture of audiophile products and have been building speakers for over 30 years. I purchased the 'Super 8 Alnico' drivers to use in my reference R&D system for evaluation of the high end audio products my company manufactures. The 'Super 8 Alnicos' are among the most MUSICAL sounding speakers I've EVER heard, either custom made or in a high end audio store. They portray all the frequencies they cover, from about 45Hz to about 18KHz, in a very smooth and even fashion so that no specific frequency stands out or brings attention to itself. The tones of the instruments sound ORGANIC with a great deal of subtlety, rich harmonics, and natural attack and decay.

They portray your favorite music with proper time, tune, musical flow, and organic tones and timbers as you have rarely, if ever, heard before. They are among the most musically coherent speakers I've ever heard. You would need to spend well over $5K to get anything that would even come close to their level of performance.' - Benjamin Zwickel 'I want to express my profound satisfaction with your Audio Nirvana Super 10 Alnico speakers. I have been listening to everything on these speakers. There are many passages, on many of the tracks, where there are delicate chords that simply disappear on inferior products.

On yours they are true and angelic. Voice is so clear, and the dynamics are so spectacular, that I can understand why you assert that these may be the best single point source driver on the market. Enough with hedging! These are hands down, and-by far and away-the best speaker. The harmonics and dynamics are not to be believed. I have a great friend, who plays piano, and he simply could not believe his ears.

He repeatedly expressed his admiration for the uncanny sense of the presence. Bach's Concerto for Two Violins in D has such emotion with your speakers. On other systems, the violinists seem to be merely going through the motions. But with your speakers, it is a passionate and moving duet that sounds like a soaring love story. One can hear and sense the bite of the bow on the strings. I played violin for years and that bite of the bow is almost always missing or sounds untrue. But there is no falsity in your speakers!

I know I am speaking in superlatives. But superlatives are demanded by your product. My admiration and respect for your efforts knows no bounds. I will never have any other speakers, Period.' - David Dickerson 'The 5.6 Super 12 is dynamite from the get-go.

Your product is superior. DYNAUDIO who? I have been a speaker builder for 40 years.

Your audio nirvana drivers sound and look beautiful. Thank you for providing such a great product on a working man's budget. I'll tell ya, for classic jazz these are the best sounding loudspeakers at any price. I must say they certainly rock too. You've made it easy for a speaker builder to nail it with no fuss. Goodbye power hungry cross-over. Hello single pointsource super efficient speakers.

I'm a happy guy! Thanks so much. Audio Nirvana is now my middle name.' - Chris Krupp 'Popped in the demo disc, and voila, I had the singer right there in my room! The soundstage of the T-Amp, coupled with the high clarity, super detail, and awesome transparency of the Audio Nirvanas, brought the singer and the entire band, holographically into my room. It's like watching, and I mean watching, them live right there!

The sensation was surreal and I've never experienced anything like that before. Goosebumps upon goosebumps. The speed of sound reproduction, by the Audio Nirvanas Super 8, is simply awesome. Previously, on my other speakers, I'm straining to hear what's happening in the background. The percussion was being veiled behind a thick fog.

It was blurry, dirty and groggy. With the Audio Nirvanas, it's like them being alive! Full of youth, energy, vitality and zest. The fog is gone and I can hear (see) them clearly, bright as day. I'm also able to place each and every one of the players exactly in the soundstage. Such is the awesomeness of the Audio Nirvanas. I began listening to my favorite cds, and am amazed they revealed hidden details with tracks I had listened to more than 100 times!!'

- Derrick Lim (from Singapore) 'The 6 1/2's are up and running, and are certainly everything you claim, and then some. Absolutely superb. Fast, detailed, razor-sharp/pinpoint imaging, very natural sounding vocals, stunning dynamics without a trace of overhang, broad, deep stage with a black velvet backdrop. I'm looking forward to the post break-in sound very much if it's better than this. These really are extremely good loudspeakers.Mark Franklin ' I have had the speakers for approximately a month now and all I can say is 'WOW'!

The more you listen, the more you love these wonderful speakers. I have the Super 6.5's mounted in the 3.0 cubic foot 'Tall John' enclosures and they have become my reference speaker.

Give them a clear signal and just sit back and enjoy. The Super 6.5's are easily the most musical speakers I have ever heard, they bring Jazz alive. I know many have stated that full range speakers need super tweeters and sub's to round out the sound, well that is certainly not true with these. The highs would put many high end tweeters to shame and the low's will bring a string bass right into your listening area. The musical delivery of these speakers are so far above their cost it's ridiculous. Just to think of the times that I have built crossovers, that cost more than these drivers, just makes me shake my head, because now I have finally found the sound that I have been trying to reach. They are rich, open, and very detailed.

Thanks for bringing me into the light of full range speaker design. I could not be happier with the Audio Nirvana line of speakers, they have it all. The Audio Nirvana's make all your old music new again.'

- John Parker ' The Audio Nirvanas, in 0.9 cu. Cabinets, carefully damped, sound better than any speaker system I have built to date. Everyone who has heard them agrees.

My speaker-building friend in town, who has excellent ears, heard them and was totally impressed. I believe his final comment was, 'I have never heard any speakers sound like that!' Having been a professional musician for many years, my ears are well-educated.

I have listened extensively to the Audio Nirvana 8' drivers and the 8' FOSTEX FE206E. The Audio Nirvanas are FAR SUPERIOR to the FOSTEX FE206E, having more solid bass, as well as much smoother, more natural sounding midrange and highs. If you are purchasing the FOSTEX FE206E drivers instead of the Audio Nirvanas, you are wasting your money.' -Beckon Duel 'I am very impressed with the Audio Nirvana speakers!

I am so impressed that they are replacing my Bruce Edgar/ ALTEC LANSING horn system. It is now for sale on Audiogon! Let me say that this is quite a feat to top. I am hearing much more than I ever have.

Full Range Driver Speaker Cabinet Plans

So, I am inspired with the 'no crossover, single driver sound. I (also) built a speaker system using 2 of the 10' and 2 of the 8' Nirvana drivers per side. I am now running them on a 40 WPC OTL amplifier with $10,000 Theta CD front end. The sound of your drivers, no crossovers, no output transformers in the amplifiers and the Theta CD system is the best sound I have ever heard! I am VERY pleased.' - Mike Morrow (Morrow Audio) 'My dad was a hard bit audiophile for many years. He claims he is getting sound now, with the Audio Nirvanas in the 2.8 cabinet, that is as good as anything he's ever owned.

I have to agree. My friend Mike was using VON SCHWEIKERT VR3s, a speaker that I liked and was hoping to compare with the 2.8s. We were both quite shocked to hear that the 2.8s not only were more open, unveiled, and detailed on the top, but were pretty close in bass extension as well. The VON SCHWEIKERT VR3s were an expensive speaker. The Nirvanas, in the 2.8 cabinet I built out of $60 worth of MDF and materials, had no right to sound as good as they did. Needless to say, I am very happy with the results and I am confident that I finally have a speaker I can trust to tell me how good/bad the other components are sounding.'

- Tom Rogers 'OK.I am now the latest 'true believer' in the cause of single driver speakers. After about 150 hours of break-in, it is apparent that those who are willing to suspend disbelief can experience something very special.even magical at times.The Audio Nirvana 8 inchers were a revelation.

A whole new way of experiencing music.and probably the best way. The sound stage, spacing between voice and instruments, shear depth and width, is quite impressive.

Tonality is honest to the front end of the chain.' - Paul Van Name (Gateway Sound) 'I must say there is no exaggeration whatsoever in what you claim at your website.

The immediate impression was that of a very distinct, but in no way aggressive mid, and an equally pleasant and 'shimmering' treble, right in harmony with my sound ideals. The soundstage was very well defined, both in terms of width, depth and height - true 3D.

Then, the more I listened, the more I realized that the Super 8's brought out 'micro-details' that the FOSTEX/EV350 combination wasn't able to reveal. Here was the 'musicality' that I had been longing for. I listened to Leonard Cohen's Take This Waltz, and I got the impression that I could pinpoint to the inch the varying distances from his mouth to the microphone over the length of the song. Enter the solo violin, where I felt I could establish the amount of rosin on the bow. In the duet with the chorus girl, it was very obvious from the reproduced perspective that Cohen was sitting down, and she was standing up, right behind him, in my imagination with her hands on his shoulders. I know very well that this is all mic placement and control room imagery and not the actual facts of the studio setting, but I believe that's what the producer/sound engineer intended, and that's what I heard. I listened to several tracks from Pierre Bensusan's album Spices, and I don't think I've ever heard the right-hand technique of a bass player so clearly coming out of a pair of speakers.that is quite a task for any speaker, regardless of cost, to reproduce with accuracy and credibility.

Listening to Dire Straits Your Latest Trick, I discovered that the trumpet wasn't entirely stable in the recorded soundstage (flaw in the recording?), and that I could hear the drummer varying the position he chose for his rim shots on the snare with a clarity that I don't remember from any of my previous listenings to the album. In other tracks, I could actually hear the varying amounts of compressor/limiter applied to the snare beats. You have developed some really world class speakers. I'm a very happy customer.' - Anders Rydell (from Sweden) ' I couldn’t believe what I was hearing! The detail and clarity in the midrange is just astounding.

I kept on returning to the words ‘lifelike’, ‘natural’, and ‘real', when describing the sound I was hearing.' -Thijs Bosma (from The Netherlands) 'I just had to let you know, I've been sitting here listening to these babies crank out tune after tune, and I can't remember the last time I tapped my toe this much.

OK maybe with a big 3 cubic foot bass reflex cabinet a bit more low bass can come out but, man, I'm telling you these speakers are working great in these sealed 1.75 cubic ft cabinets. I'm just smiling ear to ear! Fantastic on voice, great saxophone, nice drum sets, real, real nice! And I haven't even hooked them up yet with my high end rig, just a cheapo flea powered receiver.

Thanks for a great product.' - Robert Hensley 'The 1.3s sound simply gorgeous, with all program material; no shrillness, ample bass. Detail is amazing. Bell tones are startling in clarity, strings are very rich, full and present, the sound stage is only limited by the sound source.

Stuck one pair of Super 12's into some plywood open baffles. This is a big sound, even without the boxes. Midrange and detail just spectacular - bass presence and articulation effortless. I'm listening to everything from Bonobo to Steppenwolf.

I think you have the sound success story of the century. Thanks for a truly great product.' - Brian Jarvi 'I cannot believe the clarity of this speaker. I've listened to some really expensive speakers in my 65 years. To my ears, these are as good or better than any I have heard. I can hardly control myself!

These speakers are something else. Thank you for the advice during my selection process. All I can say is thank you and keep up the good work.' Cotton 'The mids and top end are open and detailed.

Sonny Rollins and John Coltrane solos sound amazing. The overall sound is well balanced, detailed, and instruments have good weight on the low end. These are the best full range drivers I have ever heard.' - David Wilkerson 'I am an audio technician and have been building the 'perfect system' since I was a teenager, amps as well as speakers. I am enjoying your speakers on a daily basis and everyone who has heard them agrees that they sound incredibly live. Coupled with a tube amp ( Dynaco ST70) this is the best system I have ever put together.

Thanx again.' - Jon Marek 'The sound is rich and detailed with great punch. The detail is just amazing. I played some Dire Straits, followed by Vivaldi's Four Seasons, which literally brought tears to my eyes. Never heard that sort of detail before. Very impressive all round. Following the reaction of those who've seen them, I'm going to have two plaques made up, one for each: Shock & Awe.'

- Stephen Price (from Australia) 'After 3 weeks with the Super 8 Cast Frame drivers, mounted in the 2.8 cabinets, I'm thrilled with the results! I've been chasing great audio for decades, and this is the best audio $$$ I've ever spent. It's hard to believe that an 8 inch driver, in such a simple enclosure, can produce such satisfying sound. The only problem is that I'm staying up way too late at night ('Just one more song')! A good friend, who owns $15K in audio gear, just shook his head in amazement (and some depression) after listening to my system. If I had to use one word to describe the sound, it would be 'alive', and, indeed, other speakers just sound dull and lifeless in comparison.' - Doug Bennett 'I have been using the Super 12 Cast Frame drivers in the 2.8 enclosures for a few weeks now.

Full Range Drivers

They really are sounding fabulous. Much better then my SONUS FABERS, not even close! The speakers are so transparent and dynamic, with a real ease and life to the music. Everything else now seems like it has several blankets thrown over them.Anthony Moore (from Australia) 'The 'Super 8's' just blew me away! They put my REFERENCE 3A's to shame (no easy feat).

I threw them in a crappy old pair of boxes left over from a pair of KLIPSCH KG2's (10 passive radiator in rear) and still can't get over the sound in a crummy box!' -Dave Hutchings 'These speakers are amazing! I can hear everything so clear. When I switch across to my LOCKWOODS, with 15' TANNOY HPDs (Ex Abbey Road Studios) the sound now seems blurred, without definition between the different instruments. I've been playing my old studio multitracks and everything just sounds great.' -Gary Stoner (from the UK) 'I have no words to explain how warm and perfectly balanced the speakers sound.

I was blown away by the most natural response (and) effective output. We were totally speechless at the rate of sensitivity, clarity and depth. We are seriously thankful for your technical support and guidance.' - Mahmood Hayat (from Pakistan) 'I received the speakers today and they sound excellent.

They have much better detail, pace, and tonality than the MIRAGE OM-9. The Audio Nirvanas sound great.' -Stacy Bragg 'I just completed a pair of Minimonitors with the Audio Nirvana 8' speakers and am delighted with them. When I compare them to my PARADIGM Titans, it is like comparing a high resolution image to low res, if I can use a photo metaphor.' - Scott Cullen 'The soundstage and dynamics, from the Super 12 Cast Frame, leaves the SONUS FABER GP's way behind.

The mids, highs, and mid bass are totally in a different class. You were correct, (by comparison) the SONUS FABERS sound like they don't have tweeters. And the SONUS FABER GP's cost about 6 times the price. The high end response is amazing. Very revealing is an understatement.

Your speakers are amazing. To be totally frank, they are nothing but perfect.' - Paul Wood (from Australia) 'Initial impressions are: Very sensitive, great imaging, stage and presence. Smooth and detailed, plenty of bass (these are horn loaded into floor-coupled labyrinth). Surprisingly good on complex orchestral passages (tried some Mahler, Wagner, Dvorak), and just magic on chamber, piano and acoustic.

Rounded off the evening with the Janet Monheit DVD, wasn't aware of the speakers at all, they just disappeared. I expect them to be even smoother when they bed in.

Excellent units, very pleased. My TANNOY Broadcast Monitors are destined for the bedroom'- Ken Thornton-Smith 'Just wanted to drop you a line, after listening to a pair of your Super 10's for four months now.

They continue to become more refined as time passes. I would have to say that these are the best speakers I have listened to. What is the most pleasant aspect of the Super 10's, is the three dimensional nature of the sound stage. Well microphoned acoustic recordings give an illusion of being in front of the listener at a specific spot. You feel like David Sanborn is standing in front of you.

Nuances of the recordings are evident; you can hear David take heavy breaths between phrases. The highs (are) detailed, with no harshness. The 10 watt SE amplifier fills a large 20 x 20 room with sound which testifies to their sensitivity. The bass response is there and acceptable with acoustic bass recordings. Upon arrival of the drivers, I found the shipping container, box, and associated packing materials for the speakers were excellent. The quality of the construction of the drivers is impressive, at this price point. Front aesthetics of the drivers are top notch; I hate to cover them up with a speaker grill.

Compared to conventional speakers, with the cost of 2 to 3 drivers and cross over components, this has to be the best performance to value for any speakers, anywhere, any time.' -Michael Dubay 'I must say I might not send the $2500 AER speakers in for repair after all!

The ANs beat the AER (and also beat FOSTEX) greatly in the highs. I hear loads of detail in the highs that were not there with the AER. I can't hear significant losses of detail, compared to the AER, which is surprising given the cost difference. By far the most important factor for me is cone 'breakup'. The ANs beat the AER's handily in this area. Best value in drivers I've come across.'

- Nicholas Perry 'I purchased the Super 12 Cast Frame drivers and I must say I'm hooked. I've owned the top of the line PHY 30SAG from France, which were $2700/pr, not including the open baffles, and the Super 12 Cast Frames blew them away. The Audio Nirvana Super 12 cast frame speaker is well balanced from top to bottom. I'm using the Trend TA-10.1 that I had almost forgotten about on a shelf. This is a great combination, with either my Emotive Audio or Reference line preamp. Please Don't miss out on a great musical experience.' - Alphonzo Edmonds 'Why did it take me so long to find out about this?

If I can build these things, anybody can. Loosely translated, that means build it, find any kind of an amplifier that exceeds a handful of watts, and you have instant gratification. My system that sits idle is a $13,000 custom.

I hate to sell the expensive speakers, but folks, this is just too good to be true. I even quit watching TV-well, except for football. I painted the speakers flat black and my wife loves them. She says they don't scream 'speaker.' She sits with me and listens to the tunes we listened to when we fell in love 37 years ago.'

- Jack Leebron 'I have been in this hobby for 45 yrs, since I was 15 yrs old. I have bought and sold so many speakers, over that time, I can ' t even count. I have owned SPENDOR SP1 's, SPENDOR LS 3/5's, VANDERSTEEN 2C's, MONITOR AUDIO RS6's and many, many more. These Super 8 's are the most natural sounding of them all.' - David Kaiser.

MODEL FRX2 E x o t i c F u l l - R a n g e Single Point-Source Driver for Open Baffle Loudspeakers 37Hz 22kHz response 8 Inch driver / 94 dB 1 watt/meter a pair We hand make these beauties in the USA PURCHASING NOTICE These drivers are available ONLY as long as the parts required to build them remain available. These are constructed with donor drivers that we have no control over.

The donors' could be changed or discontinued at any point so each time we replenish our small inventory it could be the last. We are hand building these drivers. This is not a production run. A 50% non-refundable deposit is taken at the time of ordering.

The balance due will be taken when your speakers ship. They are guaranteed work perfectly when you receive them and for an additional 5 years against mechanical defects of any kind. There are no returns accepted.

O V E R V I E W The FRX2 represents an obsessive effort on my part to perfect the full-range point-source driver for Open Baffle speakers at a sane cost. While the build quality of this driver will compete with with other brands costing many times the price, I don't believe any of them will hold up sonically because of the side effects of high flux low mass designs. Side effects like the occasional shouty mid-range and forward presentation or ringing that comes with the tipped up response that is characteristic of these types of drivers. The FRX2 overcomes these side effects with a unique motor assembly that uses electromotive coupling between the amplifier and the voice coil. To my knowledge there is no other single driver in the world with this technology. By redesigning the tuning load I was able to eliminate the added (foam) surround further enhancing the driver's uncanny speed and gaining an even flatter frequency response.

In addition to the improved electromotive correction, I added DUAL TUNING loads selectable from a tiny switch on the rear of the driver. This gives your choice of a mellower or more present sound. Microsoft vista 64 programs. Very much like having two drivers instead of one. So in the end, perhaps it was a blessing. I show comparisons in the measurements further down the page. I N T R O D U C T I O N The FRX2 design is about ultra high fidelity with lower powered amplifiers at sane listening levels.

It has limited power coupling around 15 watts or so. That means power in excess of that amount will be compressed via the FRX2's novel electromotive coupling. Point being - this is not a party speaker. It was designed for critical listening using world class gear by audiophiles with golden ears. It's SPL limitation is like the old QUAD 57 electrostatic speakers and in a proper enclosure/baffle the FRX2 has a similar albeit more dynamic sound. Unlike a panel speaker, the FRX2's high frequency dispersion exceeds most tweeters so off axis listening is superior.

It's higher total Q and 4.5mm x max makes it well suited for open baffle use. You can see that 650Hz a nearly 20 degree phase correction, followed by several more throughout the bandwidth of the driver.

Remember, this is not the phase response of the driver, this is the phase corrections being made to the driver relative to the stock donar driver. THE SWITCH The switch on the back of the FRX2 allows you to select from two different tuning loads inside the motor circuit of the driver. While easy to hear, the difference on paper looks deceptively small. Here is the FRX2 on axis plot with the switch in both positions. To the left is green, to the right is red. SOUND CHARACTERISTICS The FRX2 drivers clearly push the limitations of what is possible with a single point source driver. By that we mean they have extreme speed and top end detail that makes cymbals, bells, chimes, xylophones, horns, stringed instruments sound real.

These drivers set a new benchmark for 'in the room' presence. The bass performance and timbre is spot on and electrifyingly fast and clean with surprising weight and power. The impulse response of the FRX2 shown below clearly demonstrates how fast this driver is.

'I could care less how they measure.I have a soft spot for hard rock.when it sounds live - and the attack from these speakers combined with their ultra controlled bass made me feel like it was live. I felt every guitar note and as a drummer myself, I can tell you the drums sound more realistic on these than anything I've heard yet. Very impressive.' -Dennis Hazen Think of the FRX2 like a super high performance race car. The car is designed to perform on a good quality track and does so better than anything else.

However, run it on a poor quality track and the cars very strengths become its weaknesses. Recording quality is like the track. Recording quality is imperative with speakers like these. The differences between poor recordings and great recordings on most speakers are easy to hear, but on the FRX2 that difference is magnified in two directions.

That means the good recordings become great and bad recordings become horrible, thin and distorted. I would say this magnification effect the FRX2 has is by a factor of at least 4 compared to normal speakers. Literally, thin recordings will sound like someone removed the bass, yet warm recordings will have low bass with impressive weight, dynamics, and enough power to shake your room.

This is what happens when we design speakers that are fully honest vs. Speakers that musically interpret the source.

We hear only the recording as it was mixed. Coloration's in speaker designs are what make all speakers sound different.

The FRX2 has none, so we recommend these drivers to the serious audiophile and experienced Do It Yourselfers who have top notch amplification and source components. 'I replaced my DFR-8S drivers simply because I couldn't see how it could get much better. My favorite part of the DFR8-S was the mid-range and while Steve will probably probably flinch. When I A/B'd the FRX2 against it, the difference was enough to make the mid-range of the DFR-8S sound broken.

It really caught me off guard. These things are GOOD.'

-John Waters APPLICATIONS & FAQ The FRX2 can be used by itself in an open baffle cabinet design, or used in an open baffle design together with a bass driver as is popular with so many open baffle designs. In our Zen Open Baffle cabinet, the FRX is a drop in replacement for the original DFR8 or DFR8S drivers. Q) If I already own speakers that use Fostex or Lowther based 8 inch drivers will the FRX2 fit the existing cutout?

A) Yes, The only difference will be the screw hole pattern on the FRX2. It has six screw holes vs. The Fostex and Lowther's four screw holes. Q) I have Zen Open Baffles with the original DFR-8S drivers, can I install these myself and if I don't like them can I put my original drivers back in? A) Yes, you can easily remove the original drivers by unhooking the two wires on the back, and removing the 4 screws.

Installing the FRX2 is a matter of having someone hold it in place while you install the 6 new self tapping screws that are included. Just hook your speaker cables directly into the back of the FRX2 driver. Q) What does FRX2 stand for? A) It stands for 'Full'-'Range' Project 'X' Version 2. Q) Besides open baffle designs is there anything else this driver will work in?

A) Of course this speaker will also work in infinite baffle applications. One example is to mount it into the wall just below your projector screen as a center channel for movies. The articulation and clarity of the FRX2 makes it unrivaled as a center channel speaker in custom home theaters. And as illustrated below, it is possible to build large conventional cabinets with the FRX2 as well. THIS IS A HIGH QT DRIVER DESIGNED FOR OPEN BAFFLE LOUDSPEAKERS.
