The Empire doesn't really transmit vibrations to the floor, so I think that will help. I do still have a Gramma laying around that I can use if needed. It is a pretty large space too. Placement of the mains me about 2 weeks at the last place, and I haven't even had a chance to fire the system up here. Neighbors probably aren't going to like me
The room seems to have decent acoustics so far too; just hooked up my little shelf sysetm to play some music and it wafts up into the vaulted ceiling area and doesn't echo. Will hopefully be actually getting things hooked up so I can fire things up. This system may actually be too much for the apartment and I've been pondering stepping down to a 3.1 or even a 2.1 setup and moving the rest of the gear up to the house.
The TV mount is a Bell-O piece, since they don't allow mounting on the wall, and since they don't allow wall mounting, I figured in front of the window would work out. The Salamander version is $600, the Bell-O was just $150 and basically attaches the same way. Gonna put curtains behind the TV and it will extend out a bit behind the speakers as well, and hopefully helping with acoustics a bit more.
