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.

Bullitt,
I understand when listening in corrected mode it's suggested the speakers be placed against the front wall for best effect.  So I'm wondering, did you place them that way and then move them out into the room in uncorrected mode?
Wow grannyring, thanks for such an informative and detailed post. You are giving me the motivation I need to try doing some of the mods to my DI's......especially since I'll have the DI SE's in case I screw up my DI's trying to mod them. Thank you so much for the detailed parts list and reasons for your changes. I wish I could find someone like you to hire to fully mod my DI's like you have. 

With bullit's, Kennys and grannyring's endorsement of the Lyngdorf it's a product I will definitely try out next year ( my audio budget is shot for this year!). It's a difficult product for me to wrap my head around as its hard to believe one small box could do so much......and do it so well. But then it's hard to believe the DI can sound so good for so little. To think having only a source, the Lyngdorf and DI's and have it produce amazing music, well, it baffles my mind. I need more components than that! Lol. It will be like my Bang & Olefsun system I had many moons ago, but better sounding. 

Thanks again gents for sharing. 
Sorry for the typos as I used voice activation on my iPad. Ugh! I also forgot to mention the external board will be placed in an attractive wood case in time. The Beta woofer with the upgraded board really improved the bass in my room. You may not need to change the already very good Eminence woofer in your rig.  However, do change out the electrolytic cap!

I bet they sound much better than the SE’s :)

I would like to note that those with the Lyngdorf 2170 try a 90% Romm Perfect reading instead of a 99 or 100%. In my room it was taking a bit too much bass away so with 90% I have more lower mids and bass. Thanks evolvist for the suggestion.

$1800 + 40 hours labor=years of musical enjoyment. Wow, fantastic!

Thanks so much for sharing your efforts.
