While SVS is heading my list, these are under consideration as a sub choice (SVS's size and look may result in wife issues). I was wondering if anybody has had a chance to compare / listen to them. Based upon reviews here, the Rava is also a candidate. They will paired with bookshelf speakers and cross over between 60 - 80 hz. Roomsize is probably greater than 3000'^3. Intended use will be movies first and music second.
