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.

This speaker line looks very interesting. There is a Tekton owners thread at...http://audiokarma.org/forums/index.php?threads/tekton-owners-thread.611768/page-44

As Almarg pointed out, sensitivity on the DI is actually lower than 98dB due to the 4 ohm nominal load. There are other models that were rated using 2.83 volts/1 meter that have actually measured lower than spec due to nominal impedance. But, in all cases, speaker sensitivity was still well above 90 dB.
This is really the only negative I could find about Tekton.

@mac, I wanted to note this inconsistency in how Eric specs his speakers since it has been commented on in other forums. It looks like the majority of the speaker line is 8 ohms nominal, but a few models are 4 to 6 ohms and are measured using 2.83 volts @ 1 meter and rather than 1 watt @ 1 meter/8 ohms. An important spec when choosing a tube amp.

Interesting points that Al has raised on how specs can be manipulated, (not saying that there’s any cheating going on). Regarding Stereophile’s findings with the Enzo XL, the Tekton’s seem to have resonant cabinets, even measurable on the impedance/phase curve, although these resonances should not affect performance.
I found several high-level resonant modes on all cabinet surfaces, with one at 301Hz the strongest on the sidewalls level with the bottommost tweeter and on the rear panel. Another mode, at 262Hz, was strongest on the top panel, while a mode at 414Hz dominated on the bottom half of the side panels.
All of these modes are of high Quality Factor (Q), so may measure worse than they sound. Also, the Enzo’s high sensitivity will work against these resonances being as fully excited as they are in my measurements.

Also an easy speaker to drive. That’s good news, as I am becoming more interested in trying out one of these speakers.

@strateahed , using an active sub on a full-range speaker with extended bass will provide the amp with an easier load to drive. The amp needs to use a higher amount of current to drive the low frequencies (more air to push), so if the sub can help with the low-end, then the midrange and low-mids will benefit by getting quality power from the amp with with no clipping.
If it's a large room, a subwoofer is a benefit to the sonics of the tower speaker.

The Primus sounds extremely dynamic, but that room needs some acoustic treatment. In the other Pendragon videos, they sound thin and bright, but again the rooms are not treated, and they are not shooting from the sweet spot.

I wonder about the smoothness of the tweeter array based on those examples.

@charles1dad ,
Drum solo at the beginning of Eleven is unreal cranked to 11 ;-). You can check out a video of this on YouTube on the Pendragon to give you a little bit of an idea.
I wasn’t comparing the performance of the Pendragon to the DI, (which seems to be in a class of its own in the Tekton line). Simply making an observation on this speaker and that it will not provide optimal SQ when demoed in an untreated room.

I’ve been following this thread and absorbing information regarding a possible speaker for my 12’ x 16’ room. Enzo 2.7 seems like a fit at 40" high and dual 8" drivers, and has a similiar tweeter array to the DI.
I’ll need to research this further. Any comments on the Enzo 2.7 are welcome, as long as you feel it adds to the discussion.
