One sub or two?

I owned a single REL Storm III, then added another and hooked up as true stereo. I like this setup. And I have owned several other REL subs - they are all awesome, but I definitely prefer the "ST" series over many of the newer models... I LIKE DOWNFIRE!!!

Agree with Loydc comments. I used a single REL for few years & then upgraded to two RELs. The improvements were very evident. Imaging improved the most. Although they say deep bass is non-directional this is something you will immediately disagree with once you hear 2 subs.

Crossing over at 40hz the bass wave is so large it is impossible to distinguish its location...however one has to have true full range output to do this...and a speaker either images well.or it doesn't...regardless of a sub

Phasecorrect...

Two subs in almost ANY room will sound better.

what do you connect the subs to? to the L/R speaker? or to preamp?
