Tekton Impact

Yes, a comparison of the Impacts with the Spatial M3s would be appreciated. Actually Eric has his own Open Baffle speakers which are down-priced from 3K to $1750....these were given a full 5 star rating by Teajay, just like the DIs.
Powerglide,
Eric seemed to feel the DIs weren't much of a step-up from the Impacts, but you're using a sub-woofer for the latter. I don't think anyone has felt the DIs need reinforcement at the bottom end. Apparently the Impacts are lacking some slam....but I guess that's to be expected at that price point.

Yes Lancelock, and with the new M3Triode Master 16 ohm variety, I am just extremely curious. I have no way of hearing them though, although both have money back guarantees, it would be a hassle as well as expensive to return them.

I also have no way to hear the DI's. I would love to hear a pair if anyone is near Maryland or D.C. Mark Schneider has some Tekton speakers In his listening room. I'm trying to get him to get a pair of DI's so I can hear them.

Electrons are brand new. I received I think what is the 4th pair this week- blown away. Got all the upgrades- it is the mini me of the DI vs the impact being that. Everything sounds right with these speakers- hard to explain, but the home theater review review is spot on. 

Love these, no more switching. 

Lula,
The Impacts are rated to 30hz and to my ears do very well on the bottom end. The reason I have always used a powered subwoofer is to obtain a full range system since I listen to organ music. Also, I feel that supplementing the bottom end with a powered subwoofer allows the amp to work a little easier and more transparent. Picking up from about 7hz in room to 30hz gives me the "slam" I desire, also including loudness control.
I believe the DI's would add to my enjoyment with there additional mid and treble drivers, but may overload my room in the bass region without the ability to adjust for bass volume.
