Anyway, I'm going to try a heavy duty isolation pad for my sub, that costs $125 from a website http://www.acousticalsolutions.com/p...ation/pads.asp that hopefully will decrease the sound below at least slightly. The people I spoke to there basically said there's no way that this will work 100% but it will help. Here's what I'm getting:

Alpha Isolation Pad
Isolation PadIsolation Pads are high grade neoprene isolation mediums which can efficiently and economically reduce structure-born noise and resonant vibration. The most common uses for the product is to decouple (?float?) floors within studios and home theaters. Other applications have them placed under machinery, grinders, compressors, metal panel enclosures or other common sources of high intensity noise levels. Acoustical Solutions offers two types of Isolation Pads. The standard isolation pad comes in a 2?x 2?x ?? thick pad with a 40 PSI (Pound Per Square Inch) rating. The Heavy Duty Isolation Pad is 18?x 18?x ?? thick with a 45 PSI rating.
Good choice. It will not totally eliminate the boom, but with the combination of turning the sub down, and the islolation pad, it will help tremendously. One of the best ways to reduce the sound of your sub bleeding into other rooms is to de-couple it from the structure. The Isolation pad with do that nicely. It will also tighten up the response of the sub in-room by slightly raising the sub out of the floor to ceiling mode or node.
