Stereo Subwoofer Pairing

Note that one should try listening with the subs and main speakers placed well out into the room while you wedge yourself into a corner to listen. This might seem ridiculous, but as an audiophile (and hey…aren't we all?) you should try everything possible to hear all sonic options, or, like myself, don't.

I use 2 differing REL models from the same era (Q150e, Q108 MKII) wired together getting their signal from the main tube amp. With bass I've found that the tone indicating where a bass is in the mix comes from whatever higher frequency overtones (or simply tones) are there so they're basically mono in their low range duties. 2 subs work better though to smooth out room nodes as perceived from the listening spot, with one sub (the larger Q150) right behind the left speaker, and the other against the right wall so I can stick it in a window for deck listening (with a couple of monitors also stuck in the windows powered by another amp). I agree that keeping the RELs lower (but properly matched to the mains) with higher gain works best.
