Hi, My 10 year old REL Stadium sub has packed-up and I want to get another "musical" subwoofer for both movies and music (mainly music!). I like REL and I'm interested in their new "remote controlled" sub, the Storm 5. But I'm also hearing good things about the B&W PV1 bass ball. Which one is the best for a musical and tight bass reproduction in a corner of a 12 by 14 room. Any other suggestions? I have £1000 max. Thanks, M.J.
