Looking for feedback from anyone who has tried or uses Danny's past audio show set-ups using sealed servo subs in the rear room corners running out of phase.
I plan to use two open baffle subs I have along with a Dayton SA1000 amplifier, which contains controls similar to the Rythmik A370 amplifier. My main speakers are Super-7s.
I am trying to reduce low bass frequency resonances I have in the front two corners of the room. I have tried broad band bass traps but they do not work - stacked four 17" x 17" GIK Soffit Traps in one corner with no impact on the resonances.
Using the Stereophile Test CD bass tones the most significant ringing I hear from my listening position is from 40 hz thru 100 hz; listening at the rear corner of the room at the floor 40 hz and 50 hz are producing the resonance.
My room is 15' x 24' x10.5' with quite a bit of GIK Soffit, Monster, and 244 Bass Traps in the front half of the room. Speakers set up on the short wall. I have some treatment in the room's rear corners and wall but I don't hear much improvement from them.
Why am I trying open baffle subs instead of sealed servo subs? I can try my open baffle subs purchasing a Dayton SA1000 amp for $515 with a 60 day return option. Two F12 Rythmik Sealed Servo Subs would be $2,520 with no return option.
Anyone have some words of wisdom for me?
