Do I need a sub woofer to match my ATC SCM11s

If you want really professional sub I can recommend the ATC :

Regarding power cables I am using Atlas cables but they are quite expensive .Wireworld and Audioquest have very good power cables in reasonable price.

Thanks! I was hoping to spend a little less than ATC's entry sub. I'm going to a Rel dealer after work to have a listen. Anyone have any experience with them? Seems like their emphasis is on music and not home theater.

REL used to have separate models for music or home theater, not sure if they still do...I had one for music and it was excellent, and neither large nor expensive

Can you separate the amp and preamp section on the Hegel? If you can’t do that you will be wasting your money on any sub with a high pass filter option including the JL E110. You can save some cash getting the JL D110 or D108. Since you will be running your speakers full range with any sub you decide to get!

jeres8860,

     Do you have a budget for your sub?
