After adding a second SVS 20-39 PC+ to my setup I ended up placing the new sub in a corner within about 4 feet of my right rear QS8. I have noticed that certain frequencies from the sub will produce a ratttling of the QS8 wall bracket. I covered the screw on the back of the QS8 with duct tape as I thought maybe that was the culprit but it still is there. I think that the rattle is coming from the mating brackets instead. Anyne else have this problem? If so, what did you use where the bracket surfaces mate to eliminate this?
Thanks for any suggestions..
