Two small RELs or One Larger Sub

I added a REL Q108II as I needed something I could put in a window out to my deck from time to time to add bass to a separate amp/speaker rig (signal from the same preamp however)...when not in the window the deck amp is off, and the 108 remains in the main rig getting its signal from the main power amp. In any case, that's how I wound up with 2 subs and somehow 2 really does seriously add a lot to the overall musical fun.

I use 2 RELs from an earlier era and they're amazing...a Q150e (10") and a Q108II (8")...bought them used for 200 bucks each few years ago. I also have a "pro-studio" monster sub (in my studio) that's flat to 19hz and I've dragged its 92lb high powered mass into the hifi room to see what's what...it worked fine but...meh...the 2 RELs are enough lowness...I don't like DSP as it seems to be somebody else's "electronic opinion in a box" (I'm a pro sound tech so I could simply be a Luddite) but they may be a useful shortcut for some. I think you can adjust REL's enough to make them easy to use and enjoy...2 are good...
