Again, the real problem wasn't that the big speakers were overpowering the room, in the sense that there was just too much sound pressure or the bass was boomy and obscuring the sound. Quite the opposite. Although the hotel rooms weren't all that much smaller than some dedicated listening rooms, they were constructed differently, with reinforced concrete floors and heavy wall-to-wall carpeting. That's great for sound isolation between floors (and keeping the hotel upright), but bass and general impact suffers. I'm afraid Jeff's handiwork with the passive driver tuning didn't get a fair chance to shine. I actually had to walk up and check which speaker was playing during one cut with lots of deep bass content. It turned out to the Song Towers. They sounded almost as good as the HT4's in the bass department. But they sure don't sound that way in my home, which has very well constructed hardwood floors throughout. And, to be fair, more room for the speakers to breathe.
