To tell truth I don't really remember, you go to so many rooms in 3 days they kind of blur together. I just remember being bummed out because it was such a mega system and was hoping for much better.
The Quad room, sucked also and I am a big fan of planer speakers. They sounded dull and the imaging just was not happening at all. Several of the rooms had some kind black curtain thing going around the whole or part of the room. So who knows what kind of acoustic treatments they had, if any. As you could not see them, on the other that could be a lot heavy room treatment to ship to a show.
At these shows unless you just get lucky with room acoustics, or have someone who really knows how to set up a system. Using room treatment (some just prop a mattress up against a wall) and maybe some EQ, not to mention the time time factor, sometimes they only have a few hours before the show opens. This does not inspire a high rate of success. They couldn't even get the stereo Magico speakers in that room to work right.
I am sure that subwoofer would be awesome set up in a proper room, with some time and skill to work with it. This is the luck of the draw with hotel demo rooms, even decent sized one's, that can be L shaped, or have funky alcoves, HVAC's that rattle, etc...
A trip to a brick and mortar dealer, should in theory be better. At least they don't have the time factor to work against, but I have still heard boomy bass in not properly treated listening rooms.
