I had a similar problem that was solved perfectly by Rives' PARC. Well worth the investment, but make sure it's set up by someone competent, optimally using Rives' BARE system.
Smoother bass by running woofer out of phase?
In my dedicated room that is furnish with bass traps, I still get to much bass energy on bass heavy music. I discover recently that in bi wiring my speakers (ML Vantage)I wire the woofers out of phase;the bass bloat goes away and I have greater detail from top to bottom. What is the explanation of this and is this a recommended "fix" in dealing with excessive bass? Thanks, Sam
