Hey all,

I have a 2150 that I used mostly for music and I'd like to add a subs to fill in the frequencies from 60hz on down. My mains speakers are Kef 104/2's that really only go down to 55-60hz, but the mids and highs are really nice, so I'm reluctant to just buy another pair of floorstanders with greater bass capabilities.

The thing is, I know I can connect one sub to the 2150 easily enough, but how about 2 in STEREO? The only way I can think is to use the speaker level connections, but how about line level? What connection is better anyway for this kind of application? Thanks!
