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.

Eric,
        I would imagine that there must be some sonic difference between the 4 and 8 ohm version.  There must have been a reason that you brought out the 4 ohm version originally. I want to congratulate you for turning the high end of audio upside down. I heard your speaker at Teajay's house and it is amazing for the money charged. Is anyone showing the speaker at Axpona? Mike Kaye of Archon Audio is in Libertyville and not that far from Axpona. I wonder if he might be able to organize a listening session for those coming into town. At some point during the weekend.  I can assure that people will laugh at what Eric offers compared to they will see at Axpona. 
Thanks Charles. I almost don't want to hear the Frankensteins, I'm afraid I'll like them so well that I'll need to spend more money yet again!

Im not sure if I'll need the 8 ohm DI's. Teajay is having great success with the 4 ohm DI with one MZ2-S and I'll be driving my DI's with two of them bridged as monoblocks. That will give me 70% more output......not that 70% more than 1 is a lot! 

The LTA specs show the MZ2-S output at 1 watt into 4 ohms and .5 watt into 14 ohm. Let's say that makes it .7 watt into 8 ohm. Is there any real advantage of .7 watt into 8 ohm over 1 watt into 4 ohm? I know Al will have the answer!
Mac,
Good point in that the LTA amplifier 1 watt seems to have no problem with the 4 ohm DI per teajay. .7 watt to 1 watt is a negligible difference,  but generally speaking a higher speaker impedance load is easier on the amplifier in terms of driving it. May be a moot point with the LTA ZOTL.

Thanks, Mac. And I believe I do know the answer. I believe the answer is that it is unpredictable :-)

It will depend in part on how the impedances of each of the two versions of the speaker vary over the frequency range, in terms of both the magnitude of the impedance (i.e., the number of ohms), and the phase angle of the impedance (the degree to which the impedance has a capacitive or inductive component, as opposed to being purely resistive). And on how the amplifier reacts to those variations.

It will also depend, of course, on whatever intrinsic sonic differences may exist between the two versions of the speaker.

BTW, concerning bridging the LTA amps, I infer from various statements at their website that when the amps are used as monoblocks they are not being used in what is usually referred to as a bridged configuration. They are being used with the two channels connected in parallel. What is usually referred to as bridging generally provides much more than a 70% increase in power capability (potentially/theoretically as much as a 4x increase, although most designs fall short of realizing that much of an increase), but is often reported to compromise the sonics of an amplifier relative to the sonic quality the same amplifier provides in stereo mode. Especially if the amp is driving a low impedance speaker.  So presumably/hopefully that sonic compromise would not occur with the LTA amps if they are "bridged," although the resulting increase in power capability is not all that great. (A 70% increase in power is about 2.3 db).
