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.

Tube regulated power supply? A very nice touch if that is being done. Fun stuff.

Iaaduionut,
26 db of gain is a "lot" of gain for the line stage. Your speakers are pretty sensitive at 94 db . My speakers are 94 db as well and my Line Stage has 10 db of gain. Most often I am using the volume control (VC) in the 11AM to 2PM setting. With your 26 db of gain you may find your VC limited to a very narrow range of use and probably below the 10AM level or else it becomes too  loud. I trust Aric’s judgement but 26 db is a very high level of gain. Is the gain level adjustable?

charles1dad's,

Agreed, and so Aric made the gain adjustable so that I have more play in volume settings.

Hey guys! First, thanks Brian for posting about the Motherlode! Secondly, the gain needed for a line stage is dictated by the amp- not the speakers’ sensitivity. An amplifier has a voltage and impedance requirement at the input - to drive it to full output. One amp can need 10 db of gain while another needs 25, and yet another 35. Respectively a phono stage provides over 40 db of gain to bring the cartridge level up to line level. There are many 6SL7 based preamps, and even 12AX7 preamps, and the gain is adjustable on the preamp output. On the same (but obscure note), a McIntosh schematic I recently looked at has no less than 4-1/2, 12AX7 stages- per channel. One single 12AX7 stage can drive a 6550 tube to full output. Now THAT’S a ton of gain ;-) Best regards, Aric
