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.

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.

@grannyring,
Thanks for the detailed info on your DIY mods on DIs.  Time to look for someone locally who can do this for a fee.  I was/am interested in the SEs but this has me scratching my head.  Perhaps Tekton could offer these upgrades and call it DI Ultimate for folks like me who are not DIY savvy.
