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.

@david_ten ,
Still is.
I was providing some advise on "passive preamps", which not many people use. So this was a helpful post. You have issues with helpful posts?

Still "is" what?

I asked you a simple question about a previous post. 

Did you see a question or response or any comment to the post you made here on 7/19?

I don't. Do you?

II woul get in touch with Triode Labs and ask them how much gain does the 2A3 SET provide (knowing your current amplifier has 26 db as a reference). With the much more sensitive Tekton speaker you may be perfectly fine using the Truth.

You may want to check to be sure the 2A3 will handle 4 ohms. It says 16 or 8 on their site and Eric doesn't like to build 8 ohm versions. He believes all his effort to build efficient speakers goes out the window with that version and if an amp won't handle 4 ohm, you need a different amp. His opinion, not mine.

Lpretiring, if the specs on the 2A3 amp you would be purchasing correspond to those of the 3.5 watt SET amp described in this Triode Lab datasheet (which is indicated as providing 4 ohm output taps), it can be calculated from the 3.5 watt power capability and the 500 mv specified sensitivity that the gain of the amp to the 4 ohm tap is about 17.5 db. The sensitivity of the Electron is spec’d at 95 db/2.83 volts/1 meter, which given its 4 ohm impedance corresponds to 92 db/1 watt/1 meter.

So assuming these specs and those on your existing speakers are reasonably accurate (which is not always the case) you would gain about 5.5 db due to the speaker change and lose about 8.5 db due to the amp change, for a net loss in gain of about 3 db. Not a great deal, which on a typical rotary volume control, viewed as the face of a clock, corresponds to less than 1 hour of rotation.

Also, while I haven’t looked into the specs of the Truth, the 100K input impedance that is indicated for the amp on the datasheet I linked to should be a fine match for most and probably almost all passive preamps.

Good luck as you proceed. Regards,
