New Spatial Audio M4 Ultra

@dbt  Thanks for the info. Steve Guttenberg had a little summary on speakers at the NYC Audio Show and he mentioned a bunch of the open baffle speakers including the Spatial Audio Labs which were part of a presentation by LTA.

Guttenberg didn't mention which speaker it was but I thought it was either the X4 or X5 based upon the AMT and the woofers seeming to be the same size. Guttenberg says he may review another Spatial Audio Lab speaker but didn't say which one and he also said he might review a "new LTA big integrated" which I would guess would be either the Z40+ or the Ultralinear +. 

The X4 is about 3" taller than the X5s and has different speakers along with the passive woofer. 

I still would be interested in hearing from anyone who has heard the M4 Ultra's tweeter and can compare it to the M3's tweeter or even the AMT tweeter on the X line. 

@dz13 No problem concerning the info.  I own the X5s with the active subwoofer, but I prefer the X4s after hearing them.  Also, I saw Steve Guttenberg’s YouTube video that you mentioned.

Hi dbt, I also have the X5's and they are very good sounding as many have said.  Just curious what you preferred about the X4s?  Obviously the electronics, DAC and room will be much different that what you have so that would influence the sound a lot.  Clayton uses top notch equipment at his shows that he feels synergizes well with his speakers.  

I'm not looking to change my X5s to get the X4s as that would most likely be more of a lateral type move and I use lower powered amplification so the X5 is a better fit for me.

Just curious what you felt sounded better as I'm sure he tweaked the crossover and the sound may be a little better.  On a recent call I had with him he said both models sound virtually the same and it would be hard to really pick between them but I'm sure the X4 is a little better as those are the speakers he currently uses at shows.
