I've been putting off upgrading my subwoofer practically forever. Considering what you can get for your $ I'm thinking I might be OK with just a single AV123 MFW15 shipped for a little over 700$. The only regret that I would have would be if I missed out on "the sub of the year" if I ordered now vs. June. I guess what I'm asking is should I hold out a couple of months and see if Hsu or SVS [or some other ID bang-for-your-buck-sub-company] come out with something unbelievable or should I just get off the pot an make an order sooner rather than later.
