I would be most interested to know with the Trinnov setup whether your obviously very expert installers had to do much manual adjustment (using the Trinnov's Bass Management functions) to get the sound right, as against just leaving it to the Trinnov auto optimiser alone. I found I had to tweak the bass manually, but these things are often a matter of taste, shape of room, absorbent panels etc.
