Have never used a separate sub before, but am considering adding an EP175 sub to my 2-channel system. I am currently bi-amping a pair of M60's with a Cambridge Audio integrated (A500) and power (P500) amp.

I believe that I can run the sub out of one of my amp's pre-outs. Will this still allow the M-60's to run full-range when the sub is powered-up, or will the sub take over and limit the low-end response of the 60's? Are there options or better ways to hook up the sub, other than going through the pre-out on the amp? With a sub added to my system, will the low-end still sound balanced, as opposed to coming from a focal point based on the subs location (i.e., corner of the room)?

Appreciate any input/advice/comments.

Cheers.

Joe
