I just purchased a new pair of rear-ported monitors (Usher X-19) and am very pleased with them with one footnote. In my room, I am only able to put them approximately 12" off of the back wall. For most music, this isn't an issue but for some bass heavy music, I feel that I am getting a mid-bass hump. Is there anything that can be done (sound dampening the back wall etc.) or am I just out of luck with this type of music (most often bass heavy jazz). I have B&W subwoofer that I haven't used since I purchased these speakers if that needs to be put into play.
Thanks for your advice.
Jeff
