Major innovative break through: The new NSMT Loudspeakers reference speaker

In the next two weeks my Stereo Times review on the new NSMT Loudspeakers reference System Two will be posted. I wanted to give a heads-up to the GON members because I consider the System Two, which is composed of the Clairvoyant Monitor and SUB-DUO active band-pass subwoofer platforms to be a revolutionary break through both in performance and retail price $15,985. For example I compare the NSMT System Two to a great speaker, the Stenheim Alumine Five SE Dynamic Loudspeaker, and found the NSMT System Two to be superior in it's performance. Punch line- The Stenheim Alumine retails for $72,000! For all the details of why I came to the above conclusions take a look at the review when it is posted.

Hey, GON members

Did any of you visit this room? If so what was your "take" on its performance.


Many thanks to our Chicago area dealer Mike Kay (847-687-4800) who loaned us the wonderful sounding SPL amplification, Black Cat cabling, and Puritan PSM 156 power conditioner. A special thanks to Koby of Hi Fi Logic (973-313-9080), our new Jersey/New York dealer, for driving down to help run the room and for providing the wonderful sounding Resolution CD  player and Aurender Music server. A big up to long time friend and former dealer Christopher who drove down from New York to help run the room. Could not do it without you!

Many thanks to the people who came to our room. The debut was great. Many people thought the Clairvoyant System Two were the best speakers at the show. Several people made return visits.

The room was difficult to work with. The first day, Friday, we set up the speakers at the back of the room. The soundstage was not as high as it should be. The imaging was not rock solid. The sound was not the best.

Saturday and Sunday we changed the setup to a near field setup with the Clairvoyant Monitors nearer to the center of the room and the subs behind them.  The sound was stunning. The Clairvoyants showed their prowess as near-field monitors producing a deep, holographic, soundstage, totally detached from the speakers. Great integration, great imaging.

People were surprised how the speakers disappeared despite how close they were sitting to the speakers. We demoed the Clairvoyants without the subs for several listeners who were surprised by their bass performance. Some notables from the industry came and stayed a long time. All in all, a great show.


Thanks for the updates and hopefully a video will show up to get a sense of their sound.

Hello gentlemen,

Wanted to share that at the Capital Audio fest later this month NSMT Loudspeaker will be showing the System Two speakers. I was informed that the upstream equipment will be provided by Mike Kay (Audio Archon), a NSMT retailer, and will replicate my reference system that Erol described in an earlier post. The preamplifier/DAC is the SPL Director and the amplifier is the single chassis SPL S1200. Besides, the obvious difference between the acoustic space, I use a Reimyo Tuko DAC and a SPL Elector pure preamplifier which does not have an internal DAC. 

So, I hope you attending the show will visit the NSMT room. I'm confident that you will immensely enjoy what you hear, now that I know what gear is driving the NSMT System Two speakers. Please post what your opinion is after you visit the room when you have a chance. Enjoy the show! 

Thanks, Teajay (Terry London)

I visited Terry at his home last weekend and got to hear the Clairvoyant speaker with the larger NSMT Bass Foundation active Band-Pass subwoofers and they made a difference in the over sound stage. The system is just fracking amazing on all aspects we care about in audiophile world. Great job Erol.


In the last few days I had two guests over to listen to the NSMT System Two speakers. Both are seasoned audiophiles with vast experiences with top notch equipment and systems. Kirby, who also is a bass musician, was taken aback with the total performance of the System Two's overall performance and also felt that from the lower midrange to the deepest bass frequencies was the best he had heard in a system regarding pressurizing the listening space with accurate bass with correct timbres/tonality.

My other guest Nick, was very familiar with the sound of my system and was wondering if the System Two speakers could significantly out perform the NSMT 100 speakers. He was amazed at the level of improvement that the System Two's delivered over the Model 100 speakers. We both agreed that the Model 100s are still great speakers, but not approaching the higher level of performance delivered by the new NSMT design.

Hello, Jayctoy why don't you come over to hear the System Two speakers. You are more then welcome, so are other GON members, it would be great to see you again.


The technology is very valid here.  Same as what Dunlavy was doing 30 years ago.  Time Aligned.....6 db per octave crossover with very little parts (so reasonably in phase).....and very good drivers.  I am sure they sound as described.  However, as stated above as well.  This is nothing new and you can build such a system for practically zero money......however, that does not mean that these speaker are not great.....and great for the money.  These are different things.  My own speakers are like the 100s he sells.  I use a woofer with no crossover and a set back time aligned modified tweeter on top with just a super cap and super resistor on it.  Very transparent.....$45 woofer and $25 tweeter.  Would blow your mind if you heard it.

BTW.....cryoing the xover parts and jacks would improve the sound even more.

There is absolutely nothing special about these speakers. They use the same old technology. I did not say the were bad but hey are not in any way shape or form a breakthrough

@mijostyn , +1...any dude can tinker in his garage and think that the crap he churns out is worth upwards of 20k anymore.



For even better sound I recommend changing your coil to a 12 gauge copper wax foil coil from Jantzen (go into the inside of the coil and out the outside)....also bypass your cap with a small value teflon Vcap (make sure both caps are in the best sounding direction....usually outside foil to output). Binding posts should be WBT nextgen coppers (not silver). Of course , use great sounding wire and wire directly to the voice coil wires on the woofers....not to the back of the tab but to the place the voice coil wire is attached to the tab (much more real sounding). Use my Ground Enhancers and Music Purifiers ($125 the pair) on the speaker terminals to take it to another whole level, I would also felt the entire front of the speaker right up to the surrounds of the drivers....tweeter too. Do all the above and you will have people drooling.....he he. Just call it the SE model and charge a few more hundred dollars.....everyone will want it.

The NSMT exhibit at Capital Audio Fest will be in room 641. We will be exhibiting  the Clairvoyant System Two driven by SPL amplification.

For the hundreds and thousands of people clamoring to hear the the NSMT Clairvoyant System Two at Capital Audiofest (just kidding) we will be demonstrating there. I will fill you in with the details later (not kidding).


I don't understand why you can't access the 2023 info. There is a pulldown under the Exhibitors and Brands heading for both 2023 and for 2022 shows. If you are using the Search feature below that may be that is the problem.

I have to vent a little concerning NSMT speakers. It is very disappointing that someone like myself can live 45 minutes from the speaker manufacturer's base but apparently has to travel hundreds of miles to hear these new System 2 speakers (or the Model 100) .

Hey Guys,

I'll get in touch with Erol to see if he will be at the show. I hope he will be there with the NSMT System 2 speakers so more people will be able to hear them and decide on their merits through direct experience. 


@bernardo When I click on "CAF 2023 Exhibitors and Brands" it sends me to a page titled "Exhibitors CAF 2022  Check Out Last Year's List Of Capital Audiofest 2022 Exhibitors". I can't seem to find this year's exhibitors on their website, odd as the show is only about a month away!


Under Capital Audiofest 2023 "2023 Exhibiters and Brands" lists exhibiter names and rooms.

Post removed 

Their website seems to be currently only showing last year's exhibitors, or am I missing something?

NSMT does not show up in the Capital Audiofest 2023 list of exhibiters. You sure they are attending?

Hey mijostyn,

I answered this question already why the NSMT System 2 speakers offer two "breakthroughs". First, the development of a dual driver band-pass subwoofer strategy. Secondly, the financial cost vs, performance ratio. The performance level of this speaker is off the charts. You would have to spend immense amounts of money to equal the System 2's level of performance and still might not even equal it regardless what you spend.


There is absolutely nothing special about these speakers. They use the same old technology. I did not say the were bad but hey are not in any way shape or form a breakthrough. 

Hey Erol,

Thank you for the kind words towards me regarding being a good host. I'm really glad you finally were able to hear your System 2 speaker in the context of my system and acoustic space. 

So, if any of you Gon members who live in the Chicagoland area and would want to come hear the NSMT System 2 speakers, please let me know and I'll arrange it for you.

Teajay (Terry London)

Last Saturday, my friend Christopher Stanley, from New York, and I, flew out to Midway airport, rented a car and drove to Terry London's house to hear his reference NSMT Clairvoyant System Two system. Christopher owns the NSMT Model 100 speakers and wanted to hear if the NSMT Clairvoyant System Two topped his NSMT Model 100 system and, if so, to what extent.


Over the last few years,Terry invited me out, several times, to hear his previous reference system based on the NSMT Model 100s. This was the first time I was meeting Terry and he proved to be an incredibly gracious host.


His listening room is vast with a loft off to the left side. The ceiling is almost three stories high. One would not believe that such a large space would be so acoustically inert. So he has a great venue and a reference system comprised of the NSMT Clairvoyant System Two speaker system, Mark Levinson 31.5 transport, Reimyo TUKO DAC, SPL Elector preamplifier, SPL M1200 amplifier, Black Cat 3202 wires, Kirmuss Audio Adrenaline speaker wire, and Audio Archon power cords.


Simply put, his system is the best system I have heard. I am not talking just about my speakers but the overall system, in terms of dynamics, tonality, imaging etc. You name it.


On Sunday we went up to his loft to hear his Musician Audio Knight Loudspeaker 1 system comprised of a pair of NSMT Bass Foundation active Band-Pass subwoofers, Pro-Ject reference CD transport and Linear Tube Audio power supply, Pass Labs DAC-1, Threshold 550e amplifier, Black Cat 3202 wires, Kirmuss Audio Adrenaline speaker wire and Audio Archon power cords. Both systems are grounded with Puritan Labs conditioner and circuit grounding system.


The soudstage is huge, dynamic, and transparent. We asked him to turn off the Bass Foundation subwoofers. It was pretty dramatic how the soundstage lowered and collapsed towards the space between the speakers which showed the effects of the Bass Foundation subs.


We had a wonderful time visiting Terry. He extends an open invitation to anyone who is in the Chicago area to come to listen to his Reference NSMT Clairvoyant System Two system. I hope one of the skeptics here will take him up on his offer and write an objective post as to what he/she heard. If you are not in the Chicago area, a Saturday round trip to Chicago can be quite reasonable.

Hey Mapman,

Erol just informed me he will be showing at the next Capital Audiofest. I hope those of you attending the show who have read the review and are interested in hearing the NSMT System Two will visit his room.

Teajay (Terry London)

Hey deep-333,

There are two "breakthrough", in my opinion:

1) The development of a two driver band pass active subwoofer. If you read the review I make an attempt to explain the great benefits of band pass designs compared to other regular subwoofer designs. In my NSMT 100 model and the Bass Foundation platforms Erol used one 10 driver. However, to use two 10 woofers and get the pair to function properly is the technological breakthrough.

2) The other breakthrough is financial. For $15,945.00 you get a four piece reference speaker. Not chicken feed by any means. However, as a spoiled reviewer I have had in-house speakers up to $70,000 that came no were close to the performance of the System Two. So, the performance to cost ratio is a major breakthrough in my opinion.

Teajay (Terry London)

In the next two weeks my Stereo Times review on the new NSMT Loudspeakers reference System Two will be posted. I wanted to give a heads-up to the GON members because I consider the System Two, which is composed of the Clairvoyant Monitor and SUB-DUO active band-pass subwoofer platforms to be a revolutionary break through both in performance and retail price $15,985. For example I compare the NSMT System Two to a great speaker, the Stenheim Alumine Five SE Dynamic Loudspeaker, and found the NSMT System Two to be superior in it's performance. Punch line- The Stenheim Alumine retails for $72,000! For all the details of why I came to the above conclusions take a look at the review when it is posted. 

@teejay  What is the "major innovative breakthrough" here exactly? Can you spell it out a bit?

Post removed 

Hey mapman,

Just saw your post. I'll inquire with Erol to see if he has any plans of showing there or other audio shows. When I find out I will let you know.

Will they be demoed at upcoming Capital Audiofest? I always like to give products I have heard something good about a listen at shows like that.  

I just had two music lovers, and seasoned audiophiles, come over to listen to the NSMT System Two speakers. They brought their own music which covered the gambit of many genres of music. They listened for over four hours. They have heard my system over the years with different speakers, including my last reference of four years the NSMT 100 speakers. 

To say they were patently shocked with the performance of the System Two speakers would be an understatement! Across the sonic spectrum - dynamics- micro-details- tonality/timbres - amazing sound-staging with 3D imaging - powerful extended bass frequencies, they thought the System Two performed at a higher level in all these areas. 

Remember, if any of you live in the Chicagoland area and would want to visit to hear them, just let me know.

If I am guilty of trolling (and arguably am), I apologize. While I have not been active on this site for fifteen years like Teajay, I have been on it for a while now and was a regular on the AA Board for many years. I don't believe-until now-that I had ever been labeled as one who trolls. 

I further apologize for not just ignoring the entire matter since I have no direct knowledge of the product or producer. That is what I should have done. 


@soix +1.  FWIW I take all reviews with a grain of salt, but see no need at all for personal attacks.  That smacks of trolling to me: being insulting precisely to obtain a defensive response.  Teajay, thank you for your review and your participation on Agon. 


I did not join this discussion to engage in irrelevant written sparring

@fsonicsmith1 Then why the hell are you doing it?  IMHO, and as a former reviewer myself (in recovery), Terry wrote a review describing as best he could what he heard, and then he made the highest recommendation a reviewer can make and bought the review sample.  Who are you to criticize him or his perspective?  What’s your experience in audio, and how much equipment have you reviewed or gotten to listen to in your room and system to gain any level of perspective?   If you think the review is hyperbole then that’s you’re opinion, but don’t come in here throwing flames at a well-respected member and reviewer and say you didn’t join the discussion for “irrelevant sparring,” because that’s exactly what you did and have provided precisely zero to the value of this thread.  Terry has clued many participants here to equipment they may have otherwise never heard of or would’ve explored, which adds value here.  What value have you provided here, cause I ain’t seen it.  Jeez.



Hey fsonicsmith1,

I did what you refer to as the "a perfect trifecta" with sarcastic intent to see if you would laugh or act like a condescending individual. Guess I found out.

I'm very happy and proud to be a reviewer on Clement Perry's Stereo Time website. Find it to be a much better fit for me then Six Moons or hometheaterreview ever was. I like how I named this thread because of the amazing performance vs cost ratio and the difference in regular subwoofers vs. band pass technology. Lastly, I'm amused  at your accusation of my self promotion as a reviewer. I have been an active GON member for over 15 years, and have reviewed professionally for over 10 years now. I have many friends on the Gon who appreciate my heads-up about reviews on great products that they might be interested in. Brands like Coda, SPL, Audio Mirror, Philharmonic Audio, Krolo Designs, etc. that helped the members get the performance they were seeking at reasonable prices.


I apologize for miss spelling my Tekton speakers, but nobody perfect you know.

I am beginning to feel bad. You managed to misspell the word "misspell", combine bad syntax (should be "misspelling the name of my Tekton speakers") and leave out the word "is" before "perfect". A perfect trifecta.

I did not join this discussion to engage in irrelevant written sparring. Perhaps these loudspeakers are in fact quality products that will last and endure. Again, what prompted me to post is the reputation of your webzine, your sensationalist post title, and promoting yourself as a reviewer here.

Hey fsonicsmith1,

You to seem like an intelligent fellow. However, your tired and often used analogies seem like cliches  that still misrepresent  my personal and professional positions. There are many high-end speaker companies that charge ridiculous sums of money and build speakers with mundane/average internal parts housed in very pretty enclosures. Some of these come from countries known for high manufacturing standards (Switzerland/Germany) so part of the propaganda is that if its origin is one of these countries it must have amazing built quality. It ain't necessarily so! In all my reviews, with a few exceptions, I'm looking for small artisan companies that design, hand build and use high-grade materials that lead to superlative performance. (examples-AricAudio-Linear Tube Design) Not just great for the money charged, but shockingly good and performs at levels that would cost thousands of dollars more. The "Big Boys" often charge and get obscene amounts of money. But this is based not on heirloom quality or performance, it's often based on payola to certain reviewers, enough capital to fund large advertising campaigns, and finally appeals to the audiophiles who have to have the latest and greatest " flavor of the month". I apologize for miss spelling my Tekton speakers, but nobody perfect you know. So that's my position or what you called a BAIS, not cheaply made junk, but reporting on high grade products from small boutique companies, not the so-called "Swiss Made Level" companies that build average products, and for the reasons I stated above, charge bogus prices and laugh all the way to the bank.

1) With your statement that I put "sound above craftmanship" because I written very positive reviews historically about  Tekton Design speakers, own a pair of Ulberth speakers, shows your negative bias that many have towards this brand.

Obviously we don't know each other and in this world of exchanging viewpoints in the faceless meta-verse, assumptions are made about each other. Of course I am biased. We are all biased. But my bias is not against Tekton per se, but only against companies who put out cheaply made products. My BIAS is that a cheaply made product is no bargain at any price. 

You may or may not be aware of the many threads on multiple fora regarding the build quality and misleading published specs of the Carver Crimson tube amp. It "featured" a total piece of junk transformer. It was poorly designed so as to present a significant shock hazard. 

Quality is quality. We know it when we see it, feel it, use it. Just one example of quality is Luxman. I only have one Luxman product so I don't  think my opinion is rooted in ownership-bias. It is their head amp, the 750u. It is not even in my system at the moment (an equally quality product, an Ampandsound Nautilus head amp is in its place). 

You seem to be an intelligent fellow so I don't need to belabor the no-name digital watch vs. Swiss handmade analogue watch analogy. The former may keep better time but it is disposable junk. The latter can be easily corrected for accurate time and can be passed on for generations. 

And by the way, why do you repeatedly misspell the name of your own beloved Tekton, the "Ulfberht"? Are you sure you have a pair? 


Hey Facten,

I did not hear the Stenheim speakers in my system. I was very familiar with all the upstream equipment. Great speaker, I mention it my NSMT System Two review for two reasons. First, they have overall similar sound signatures. However, the NSMT has a better bass foundation because of the active band pass subwoofers. Secondly, the amazing price difference of $55,000, in favor of the NSMT System Two, which costs $15,945.00!
