Sub-Woofer?

I've become a 2 sub dude (subdude?) after touting the fact that one sub is fine, which it is. Now I think 2 is better, and I have to stop there as more would clog up my speaker posts (using REL high level connections only).

If you're patient you can score a great REL used. I bought a Q150e for 200 bucks (in great shape about 5 years ago maybe) then a little later found a minty Q108II also for 200 bucks. I doubt newer RELs sound any better than these things, but I have no idea. These prices might be a little bit of luck, but they show up often enough I've actually badgered friends into buying used RELs when I see a good deal. I make the the Neutrik "high level" cables myself as it's easy, and I use Canare Star Quad wire because it looks good and works great. The bass in my listening room is astonishingly musical, and easily adjustable.
