Another high efficiency design 4 Ohms @ 98.82dB (2.83v @ 1 meter).  

Is this pretty strong hyperbole? Or can this be the "obsolescence" of all other speakers?

Our revolutionary U.S. patent #9247339 (issued January 26th, 2016) allows us to literally align the moving mass of speaker cones to the harmonic spectra of the musical instruments being played. This means that, in theory, we’ve now made every other high fidelity loudspeaker on earth obsolete in one fell swoop! Again, I believe I can make a strong case for claiming that every other high fidelity loudspeaker is now obsolete or (for models that do try to mitigate moving mass) at least subtly obsolete. I’m quite confident in stating that we’re now producing the most accurate and best sounding loudspeakers ever built – period!

7 tweeters, 2 6" mid-range transducers and 2 10" Pendragon Transducers for $3000.   Hmm, you have basically 11 drivers, in a fairly big speaker cabinet for 3k.  I'm not complaining about the price, but it kind of makes me question the quality of drivers that are being used.  I'd love to hear them though!



Upcoming review by Terry London:

“Eric had communicated with me his excitement/joy for the last year and a half regarding his new revolutionary speaker design, he was waiting for his U.S. patent to be approved, that he was starting to build into his speaker models. He sent me for review a pair of standard Double Impacts, $3,000.00, and I have to share that with first listening session I was patently shocked at the performance of this speaker! The Double Impact Speakers were not just great for the money or price point, they are world class reference level speakers, regardless of price! I have had as my reference speaker for over five years a highly regarded $19,000.00 transducer that was outperformed by the Double Impacts in all important sonic parameters. The Double Impact Speakers are amazing at creating the illusion of real music with all the purity of the colors of instruments, space/air, and the “pop” and dynamics that you find in live music.”  -Terry London

I'd like to hear them too.  But in the interest in balancing out some of the hyperbole, here's some interesting banter regarding his patent regarding use of low moving mass drivers:

http://www.audiocircle.com/index.php?topic=146174.0

Eric Alexander seems to generate more than his fair share of skepticism.  I read the whole patent and struggled to understand definitively what it is he's patented.  Don't get me wrong, I'm sure they sound great.

Looking at the first post, didn't Donnie do this with his open baffle/double driver speakers?

Intuitive designing is an Art!

If I was ambitious, I would go to the Chicago Audio Society meeting next month and hear these.  I think it is actually over in Munster Indiana though.

my buddy just got a pair of these last week.  he has a pair of the  tekton cinema subs too.

i haven't stopped by to listen to them yet, but will soon and report back.

Okay, what I said in my reply #3 was a bit harsh. However, Room treatment is needed in ALL Rooms, IMO.

I just got off the phone with Eric Alexander.

I ordered the Impact!
http://www.tektondesign.com/tektonimpact.html


He told me you are getting the Double Impact signature (U.S. patent #9247339) with less parts.

I love the black/soft gloss finish and wanted to enjoy them for 60 days and hear and see what I think?!  

I have tried higher efficiency before with Zu Unions (8 ohm). They did not float my boat. However, never say never and time I try again with The Tekton IMPACT.

Eric, said he will get them on the road to me in 2 or 3 days/painting me up a fresh pair.  Sweet!


Let the Battle Rounds begin late next week:

Modified Adagio's vs. Impacts.......... .

Well, I need to burn them in for 100 hours first......... .

I also have Kimber 8TC new jacket/which might be a better fit vs. my Kimber KS6063.....but, I might be surprised?!

Ahhh yes, that is why I bought the Impact and not the Double Impact.  

Who knows? Maybe, I sell my Modified Adagio's. I kept the original x-over's to retrofit them back for the layman purchaser.  

A fellow on Audiogon "Mac" has the Double Impacts and uses a Torii MKIV. He absolutely loves them but says don't be fooled by the efficiency rating. They are a little harder to drive than you would think.

... and should be cool to compare to pair of Alnico HO from Omega I'm listening to. If on the right side of 3k they would be a nice comparison

Tekton seems to overstate their sensitivity ratings.  Stereophile measured the Enzo's at 6 do less than Tektons rating.  That's pretty significant.

I just got off the phone with Eric Alexander and my IMPACTS ship today! Whatever x-over magic he is mojo working in the Double Impact ~ is in my smaller Impact too. This guy knows how to work a Tweeter array (read the AgoN Thread on the D-Impacts) and tonal balance the collective with un-etched detail. As stated in the AgoN thread....they an I, can let marketing hyperbole go.....when the Speaker has sonic merit. It only matter's how it sounds.

Smaller, well as compared to the Doubles, yes. My Impacts are still 47 inches tall and weigh in at 71 pounds each. Nice wt. to move around myself. My Adagio's come in at 78 pounds each and are easy to navigate.

Anyway hope to have something to say about them soon. I will use the 8 ohm taps first on my ZMA for break in and then the 4 ohm taps.

Hi Ace. Always a risk. However, I am pleased with the impressions of the 2 and 3 owner's on the AgoN Double Impact/Thread. Plus, Terry London's response and input on the Thread as well.

Now, I am getting the Impacts and not the DI's....I have high hopes for them though.

As one poster stated/whom ordered a pair of DI's: "He/I have spent 300 bucks on worse things over 60 days."
(Referring to the cost of shipping them back~if he does not like them. It would be more like 220 to 250 for me from here to Orem with my lighter wt./size Impacts).

However, I did not order them to return them. Only, if I decide to upgrade to the DI's! Damn my room size.....I'll move it downstairs.  8-)

Hi Tommy. You know I think it is about time I figure out how to post pic's here. My quote function here on the forum does not work at all, but that is no bother to me.

Anyway, I wish it was as easy here to post pic's as it is on AudiogoN. I'm sure I can figure it out.
I think someone/someone's have posted the steps.....to a photo-bucket then.....etc... .

Always plan B > you can PM me your number and I will gladly text you pic's.

Perfect time for a 3-day weekend!

IMPACT's in the house!

Okay, got them and despite a stomach flu Thursday night into yesterday.....I recovered enough to unpack them and carry the beautiful beasts into my Listening Room.

Packaging was A++ and a cool way of opening the carton's.
Perfectly fit/finished/flawless they both are.
Driver's and Tweeter's are stunning to look at and top notch installation.

Hooked up/fired up. First 1.5 hour's roughly, they were getting the cobb webs out of the caps, wiring and driver's..... .

The next hour got interesting.....they started to bloom and focus locked in with images. Tonal balance is spot on, allowing detail not to be tainted by the very taunt and delineated bass...... . Soundstage superb. Timbre/Tone were shinning through in this hour too. With further burn in, their might be no need to upgrade to Mundorf Mcap Supremes.....time will tell.

I had to shut down at 2.5 hours. Whatever, mojo Eric has going in this Tweeter array fine tuned to the other Driver's......I like it! More efficient too, only slightly over my modified Adagio's.....judging by the gain needed on my ZMA knob.....but welcomed.

All I have for now. Can't listen today.....I'm off to work.  :'( Tomorrow, I look forward to putting 6 to 8 more hours on them.

PS, and of course, you know I had to go there....and get some extra SPL's out of them....before I had to shut down yesterday (damn prior agreed commitments). Oh yeah, they can go there...so can my Adagio's.....but these guys can go nuclear colossal/.....so an fitting name ~ Impact!

Modifying my Acoustic Zen Adagio's (like my Parker Crusader's were wired)....brought a next level of aliveness. However, the aliveness Terry London refers to.....is apparent even more next level in the Impacts.

Tekton Double Impact @ 98.82 dB 2.83V @1 meter sensitivity and 4 ohms, is 95.82 dB 1 watt @ 1 meter.  I think this makes sense given what Stone is hearing in loudness vs. his modded Zen Adagios.  

Feel free to school me if I'm off on this one.

Moving into my 14th hour (Forum follower's and www./readers)
on them this morning (just a reminder/I have the Impact.....not Double I's).

................they continue to open up! Timbre shading and coherence just keeps getting better (they are plenty worthy of running on my KS6063 Speaker Kables). Questioning, if I will be upgrading the Caps! Sensitivity efficiency is perfect with my ZMA and as previously mentioned/slightly more so than my modded' Adagio's.

I ran my Kimber 8TC on the 4ohm and 8ohm taps of my ZMA yesterday. I prefer the 8ohm taps (...I will revisit with more hours on them). Kimber 8TC is wonderful with these Speakers and gets 7/10th's of the law compared to my KS6063. So, recommended.

Anyway, you can tell I am pleased with these Speaker's. I won't challenge them with my modified Adagio's until I put 50 hours on them by mid next week.

Okay, I'm going to chill on my first 15 hours with these Impact's. I will put an estimated additional 25 hours on them by this Sunday and come back.............. .

Hi Stone, well I guess it's  my fault your bank account is shy a few $$$$ since I started this thread LOL!  But I'm glad you're enjoying the new speakers and I'm living vicariously through your posts 😄

I'm curious to know what brand tweets are used with your Impacts?  Since I'm a treble sensitive person ...I'm wondering if there may be other options ... that is if the ones that are in there are too hot?

That's great to hear! I'm glad those are working out for you...I really like the design concept...it does follow the simplicity and speed that you and I appreciate!

well finally got over to my buddies house to listen to his double impacts with 2x 18" passive cinema subs.  hes had these for 3-4 weeks now with prob around 100hrs.

he driving the subs with a bryston sst and impacts with manely 250 classic mono's.  with some room eq'ing going on.  speakers in background are dunlavys (i didn't honestly think these tektons be in the same league)

we listened to various lps and cd's for 2-3hrs.  

wow!  the mid bass, mid, and highs are very smooth, articulate, and effortless.  the subs blended (crossing around 60hz) surprisingly well, to the point of not knowing they were in the room.  being a maggie/ob guy now, i didn't find anything boxy sounding about these at all.  they were fairly forgiving of the room config and responded well when moved around a bit.

going in i figured those tweeters would wear me out... just the oposite.  they are very smooth and detailed.  cymbals sounded like they were right there.  

despite the poor room dimensions the sound stage was very broad/high and deep.  instruments had good separation too.  

all in all i was quite impressed with them and felt i could live with them.

Stone sounds like your thoughts are similar.

Rr, the tweeter array looks like a gatlin ready to rotate and fire 😃

Trip, I can live with them too. Wish I could have heard the big guys there. My baby Impact continue to burn in nicely. As I mentioned and you heard/listened too-I will be keeping them. I like the little extra efficiency as well. Bells and Cymbals, are coming in exquisitely. Staying with the stock caps for now too.

1800 bones (delivered), heck of a good Speaker. Are my modified Adagio's better at twice the price? Ahh, yes. However, the Impact take no guff from them and deserve to be in the same room for rotation.

However, to be fair to them and me......I need to recap them with Mundorfs. I waited 5 months to recap my Adagio's.....I'm going to season in these drivers and recap in the fall.

'Nough said.

What to choose?

To be fair to the impressive SB Acoustics Tweeters and the mid woofer and woofer + Eric Alexander's Design of the Impact Series......The Caps need to be ungraded now instead of later. I am impressed with this Speaker stock....it merits the upgrades to see where I can take them.....as I did my Adagio's.

My ears to brain for two years now, are wired for Mundorf MCap Supremes in my Adagio's. I can either recap my Impact here local/shop that did my Adagio's, or send back to Eric (or have him send me a new pair all done-I'll return ship my current Impact).

I will call Eric first and see what I/we want to do.

I am considering Duelund VSF-Cu Loudspeaker Capacitor's too.
http://www.humblehomemadehifi.com/Cap.html

But, the Mundorf MCap Supremes are such a proven winner for me..... .

Here is Eric's standard upgrade/from the Agon Thread....I will discuss with him first as I said, before I go local upgrade work.....all options (inductor coils - internal wire - resistor's too).

Caps matter! I am the stone of tone....I hear it......and the not so subtle, but sometimes subtle differences between the best of the best Input Tubes......because of my mod to my Adagio's.
OF COURSE, + the ZDSD with Steve's Output Tranny's and the ZMA with Jupiter Caps with his genius topology/voicing.
.....Kabling, is never to be underestimated either.  ;)

"There seems to be some confusion surrounding Double Impact upgrades.

Here's clarification:

1. The 'standard' Double Impact - a true expression of extreme performance within the niche of 'affordable hi-fi and home theater'. The cost is $3000 delivered for the pair. This speaker is available in any color under the rainbow and is featured in my "Soft Gloss" finish. This is the loudspeaker reviewed by Terry London

2. I have one upgrade option package to the 'standard' Double Impact and it's been available since day one. This upgrade is very popular accounting for 40-50% of all production as of today. I see that many clients posting on here own this option. This upgrade uses Cardas inputs, upgraded internal wiring, ClarityCap on the tweeter section, and an oversized Jantzen coil on the woofer section. The cost is $3300 delivered for the pair. This model is available in any color under the rainbow and is featured in my "Soft Gloss" finish."


PS-now with 50+ hours in them: The 4 ohm Taps from my ZMA seem to be the winner! The fluctuation of the impedance around this 4 ohm Impact Speaker......glad I have the 4 ohm Taps.

Small, 12 X 13, however, with proper room treatment...it sounds very good. I had the Impact too....not the Double Impact. I liked them....but I could not keep them and my Caintuck Audio OB Bass Alpha 15", modified Acoustic Zen Adagio's, DM947 Monoliths ....and be on my current journey with an NT-503 with ZBIT coming.

It pained me to return my Impact's.....with my ZBIT coming....I'm in lock down and pay my bills.  

I had the Impact as you know, not the Double Impact. Yes, the Impact are finicky just a tad....they needed to be a good 1.5 feet out from the back wall further than my Transmission Line Adagio's and they were fine. I must mention too....I do have Acoustic treatment in my room and of course for the back corner's/bass.

The Impact are fine Speaker's. Ultimately though, my modified Acoustic Zen Adagio's buried them. The Tweeter(s) alone, in my Adagio's,  Crushed them and the DM947 Monoliths.....the Adagio's destroyed as well. The timbre, treble extension and being able to handle the extreme when called upon.....Adagio's, including driver's can't be beat, by these two Speaker's mentioned. However, for 1800 bones the Impact is a value.  

Anyway, I digress, ......my OB does a lock, just behind my right Adagio front firing....with rear OB....draining to acoustic treatment behind. Randy's OB, is an absolute steal.


Oh, I had to go open a Surly Furious!  Time to play some Vinyl....and have some cleaned for when Sue gets home..... .

Oh , I would put my ZMA up against the 845 SET sound. Especially with some of the best Kimber Select I use and NOS PLAT' tubes from my uncle Kevy. I'm turning into a bit of a snob I guess. Why I also proclaimed Mr. Lee's Adagio Tweeter and Driver's where I crossed them over to be best.

Meant to add,...  I have bought my fair share of tubes from Uncle Kevy,  def a good source and quality you can trust.  Have you ever dealt w/ Andy at Vacuum Tube Services?   If not check him out,...  you talk about one meticulous OCD individual  (just the type you want picking your tubes),...   Got a great supply of highly graded and selected stuff!  No ties here,  just great experience. Fair pricing too.   Figured it was worth passing the word.  Anywho,... be well

I miss spoke, it is http://vintagetubeservices.com  Andy is a character but the kind that polishes the pins (the only correct way i might add).   He is a wealth of knowledge when it comes to the years they were made and the tooling diferences.   Call him though,  his email sits like grandpa's cell phone voice mailbox,..  lol. Full and unanwsered for months!!!  In all Honestly, call him, tell him what you have and like and where yiu want to go and he'll put you spot on it!

Stone, your equipment tag is getting a little overwhelming...
 :P  ;)

Ya know,  they are both really great amps, albeit different,..  from a fit and finish standpoint,   the Ayon is one of the nicest I have ever laid hands on.  Line Mag is solid and nice and I prefer it's sound on efficient spkrs,  but the Ayon takes no back seat to anyone in the cosmetics dept.  and for less sensitive spkrs it is killer.  The 845's are great but knowing that your running 1kV on the plates can be a little nerve wrecking knowing that if something goes wrong,  you could fry a whole lot inside very quickly,...  I honestly will prob keep the LM for another 6-12 months and in the meantime be looking for a used ZMA if one happens to pop up,...

Beo, my thoughts exactly.

I have the Double Impacts in my system now and they sound fantastic. They have an electrostat type quality. I have rolling different amps in and out to experiment. I currently have a SS Benchmark AHB2 and it's very good. Even more impressive is the 1 watt Micro ZOTL sounds,incredible and plays as loud as I ever want to listen.

Eric does have a DI coming with upgraded drivers called the Double Impact SE (special edition) for a more audiophile sound as he says. It's twice the price. I think I will stay with the DI's, very satisfying sound.

Jslateiv,  unfortunately I sold the ZMA before I got the Tektons. I wished I still had it but a I knew I would say that. My final stop will be a new LTA amp a few months away that will be 20 watts. I borrowed a prototype and it was the best I've heard with the DI's.

jslateiv;

Have you bought your speakers yet. If not; I have a pair of Impacts in new condition, that I will make you a good deal on. PM me if interested.
