I'm moving into a new condo, and tomorrow the movers arrive. While both the sub and the piano can be moved after the fact with effort, I'd really like to get the positioning it right the first time, or at least as close to right as possible (especially the piano)!
With that in mind, what could go wrong if I place the sub and the piano near one another in my living room? (When I say "near", I'm talking 1 to 4 feet of separation.) The one thing that occurred to me is that the sub might induce some resonance in the piano and cause strings to vibrate, which I don't think would cause damage but which might not sound great while watching movies or listening to the stereo. Anyone know if this (or anything else bad) is likely to happen to the piano?
While I'm interested in theoretical answers, I'm especially interested in the experiences of people who've actually placed a sub near a piano and whether or not anything bad happened. Note that the sub will be placed on an Auralex GRAMMA isolation pad, which, when I used to live in an apartment with a fireplace, solved the problem of rattling fireplace chains due to sound waves traveling through the floor. Also, the floor in the living room is hardwood on top of a cement subfloor (in case that makes a difference)
Thanks in advance!
