I just try it in a store ...
This is a good product: power, good bass, good treble and the whole super strong. It lacks a bit of personality: the sound is good, but we can not find a particular nuances with this speaker ... replace 2 of 4 by G12H * V30 would probably find that little extra.
I find it better than a Mesa 4 * 12 standard, but less good as a 4x12 NOS (NameOfSound) that really an exceptional grain, even in full v30!
