I have my 2 SVS SB12-NSD in opposite corners, left and right of my display. This is against an exterior wall. It's a single home with a good 20 feet between that exterior wall and the next door neighbor. The subs are directly on hardwood flooring. I've attached two pictures below of the subs on the hardwood (one is hidden in the corner behind the lounger). The volume knob on the subs is just over 1/4, less than 1/2 on both subs, my sub level in my receiver is set at -3.5dB, and my whole sound system, including the subs, is calibrated with Audyssey XT in my Onkyo AVR.
If I listen to music or movies with lots of bass, above -15/-12dB the next door neighbor says that his house is shaking
While buying a new sofa, while talking to the salesman about carpets etc... he said that he was an ex-electronic salesman and that I should install four vinyl bumpers (picture attached) in each corner underneath the sub. He said it would help eliminate the bass transfer to the floor and reduce (or eliminate) the vibration in my neighbor's house.
Will this work ?? If so, should I use the bigger 3/4" ones from the pic and put one in each four corners? Or the smaller 1/2" ones?
If this won't work, any other suggestions to help take away my anxiety whenever there's a loud LFE passage
