Got it, so put an expensive 1" tweeter with a 8" woofer in a well made box with a flat baffle and the crossover will fix it.

Lol .. Talk about over generalization for effect.... I guess you never heard a Dennis Murphy mod..
Could've said the same about your comment
You could but you'd be hyperbolic.. I just stated sometimes a mod does wonders..sometimes it doesn't... Imo you kinda went 0-60 pretty quick...Could've said the same about your comment
Right there, the rising treble magically vanishes, all due to a crossover mod...i have a Dennis Murphy mod , i had a pair of the originals as well to a/ b.. The effect was easily audible...2EX original:

2EX V2:
Actually, the most critical change from S2EX to S2EX V2 is in the directivity. You can see this in the DI - which is now shockingly good, near textbook perfect. Overall effect is that V2 sounds more open and spacious. Optimizing this aspect was far more complex than simple high frequency padding, thus requiring different tweeter and woofer slopes, as well as crossover point. This is an entirely different crossover, so I personally wouldn't categorize this change as a crossover mod. It has an entirely different "brain"
Very cool , thanks for the clarification... You and Dennis do some very cool stuff, he and i talked a little bit about the original 2ex, he really likes it....Actually, the most critical change from S2EX to S2EX V2 is in the directivity.

Dave compares the new version of the 340 to the Revel M105: https://www.avsforum.com/threads/ascend-se-owners-thread.629769/page-216#post-62095018

It's funny that he compared those two speakers. I just stumbled onto these new CMT-340s and while studying the measurements I kept thinking it looked similar to the Revel bookshelves measured here. The on axis response of both have a similar dip-peak-dip in the treble region, probably due to a similar baffle width. Also the estimated in-room responses look very, if not extremely similar.
In the comparison graph from Pierre Aubert' website you can see the similarity. The CMT-340 directivity looks slightly narrower overall.
I was thinking about the slightly higher directivity index of the midrange (woofer) region with the CMT-340s. Of course they are using a larger woofer size than the M105 but even when you compare to the M106 the discrepancy remains. I wonder if this is a reflection of the MTM configuration causing narrower directivity in that region. It makes me ponder which I would prefer, the 'better' vertical directivity of the one woofer Revels or the roughly +5db efficiency of the two woofer Ascend. Bass reinforced by subwoofer for the comparison of course, to make things fair. In any case the CMT-340SE2s seem like an excellent value at the current sale price.

I'm wondering about the effect of the mtm set up as related to directivity as well.....
