Harbeth 30.2 XD with 2 REL T/9x
Running 1 sub in a stereo set up is pointless.
A lot of people advocate a minimum of 2 subs but some rooms (including mine) can’t accommodate more than 1 either due to the size or arrangement. Nevertheless, there are reports that one sub can work very well, and there are few who use a single high end sub in their systems to great effect.
Instead of creating a new thread on experiences with a single subwoofer, I’ll just post this here. Have a look at the photo below which is taken from another forum. This is the top of the the line REL No. 25. The sub looks small as the speakers are huge in real life, weighing in at more than 200 pounds each.
