Tekton Double Impacts


Anybody out there heard these??

I have dedicated audio room 14.5x20.5x9 ft.  Currently have Marantz Reference CD/Intergrated paired to Magnepan 1.7's with REL T-7 subs.  For the vast majority of music I love this system.  The only nit pick is that it is lacking/limited in covering say below 35 hz or so.  For the first time actually buzzed the panel with an organ sacd. Bummer.  Thought of upgrading subs to rythmicks but then I will need to high pass the 1.7's.  Really don't want to deal with that approach.

Enter the Double Impacts.  Many interesting things here.  Would certainly have a different set of strengths here.  Dynamics, claimed bottom octave coverage in one package, suspect a good match to current electronics.

I've read all the threads here so we do not need to rehash that.  Just wondering if others out there have FIRST HAND experience with these or other Tekton speakers

Thanks.

As far as presentation with my DIs in my room, the lunatic in Dark Side of the Moon is standing behind your left shoulder. I've startled a couple of people with that effect. And that's driving them with a SS Receiver. If the imaging of the Ulfs surpasses that, it must be impressive. This effect and just the general depth/width/definition of the sound field was never as good as this with my B&W 804s. And they are know to be pretty good in that aspect. I am really looking forward to my DI SE when Eric gets to them.

The $300 upgrade version uses Clarity caps. 
Just curious if you have ever heard the DIs? You say the Sonus Fabers are much better balanced. I heard the Olympica 3 at Hansen's audio in Dayton Ohio and did not care for them much. Seemed like they slowed and rounded transients somewhat for a lusher type of sound. 
Yes, mofojo, Eric was quite open about the brand of caps and coils your $300 got you.  So not quite sure where audioman is getting the impression this is all guarded information.

Teajay, I also noted my original review that the DI's do a very nice job of conveying a sense of the venue of the performance.  I would be surprised if the Ulfs can't discriminate in this regard.  As others have stated makes one question either  room/placement issues or associated gear.  If that's not the case....well,I'd keep my DI's.
My speakers are not slow in the least ,your choice of amplifier will determine that. Yes I did here the D impacts ,not SE version, a  week ago at a audio get together .they did s lot of things well.
The Olympica-3 drivers are night and day better quality even 
Vs the As a version that I can say as s Fact. Much of the technologies is from their flag ship. And the only clarity worth 
Their salt, I have used them all is their new Copper MR,
Or Copper ESA,their 2nd in line. And Jsntzen coils are a favorite,
And mundorf supreme resistors,or worlds best Path Audio
Under 1% max .Duelund 5 and 10% are a 10,and 20% total variance .
Cabinet design build is totally an art form and specialty. 
I heard three or four of the SF line of speakers before I went with the Tektons. Everyones taste is different. I thought the lower end Sonus were ok, but the higher end speakers I thought were very good. I liked them a lot. For me, they did not leave me thinking that they were worth that kind of money and I had to have them like some other expensive speakers did. Personally, I do not think they did anything that the DIs could not, but that is just to my ears. I do have to say that the higher end ones look great. Would definitely dress up a room.
