I have a Rel Storm III and run it off my mono blocks with fantastic results. I had to build a harness to connect to the amps which sit on the floor next to each speaker. That harness links to the speakon connector at a junction strip. It integrates perfectly with my speakers which run full-range.
How to connect a subwoofer into a mono block system
I'm interested in adding a subwoofer into my audio system. I have a new Audible Illusions M3B driving Welborne Labs Laurel Iix ultimate mono block amps and ProAc 50 Signature speakers. I've been confused by material on the web as to how to do this so as to insure that the subwoofer is seeing exactly the same signal that the ProAcs receive. Any recommendations, both as to how to best do this, but also on subwoofer choices?
