@soix: By the way, the woofer towers of the GT Audio system are made using the Rythmik Audio/GR Research OB/Dipole Subwoofer kit. The kit includes a pair of 12" servo-feedback woofers and the Rythmik A370 plate amp, which includes a dipole cancellation compensation network. Best sub in the world! GT uses multiple kits per side, stacking several OB/Dipole H-frames into tall columns.

@bdp24 Thanks for that. I’ve always held Rhythmik subs in the highest regard but didn’t know they were being used by GT Audio. Interesting. |
@soix The X series use AMT tweeters, not ribbon tweeters. They do look very similar though. The X4s were used at the NYC audio show. The fully passive X4s produce really good bass! |
@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. |
