Thanks! After the carpet and chairs are in I'll have a great deal of fun fine tuning everything. So far I've just been tracking down any rattles and silencing them. I was worried that the sub may move a bit but with the isolation pucks I added to the bottom I haven't seen a shift in the platform at all (it's on wheels). Originally I had some foam isolation pads wedged between the sides of the platform and the enclosure wall but that actually transmitted more vibrations than not having them at all.
