Read up on room acoustics. You're on the right track to great sound. Your system will only perform as well as the acoustics in your room allow it to. Once you have a good acoustical environment you'll wonder what you were waiting for. Another thing that can be very helpful is a Behringer DEQ 2496 especially it bass traps and acoustic panels have to be at a minimum. At least try to damp all first reflection points and get some bass traps. Your ears will thank you. Excellent bang for the buck on sound improvement.
Advise on acoustic treatments to fix boomy bass.
Have speakers that I really like. Problem is they need to be out from back wall about 36". Closer and the bass gets boomy. They are a ported bass reflex design. Anyone have any experience with acoustic treatments that will remedy this situation and allow a placement closer to rear wall? If so, please provide specifics.
