I think your best bet is to just get rid of these speakers and find some = different ones that don=E2=80=99t have any problems that need fixing. I had a similar problem with some B&W speakers. The plastic back plates = would buzz at a certain frequency. The funny thing is that I never = recall hearing them buzz with rock or jazz music, but when I played = synthesizer music - a particular Robert Rich CD - they would reliably = buzz. There were a couple of other CDs that would show the issue. I = ended up selling them used. In fact, I had inherited them basically new = from a girlfriend who didn=E2=80=99t like how =E2=80=9Cbright=E2=80=9D = (accurate) they sounded. They were about $300 each. This is when I learned that the easy part is making a driver that = produces all of the right sounds. The hard part is an enclosure that = doesn=E2=80=99t detract from the sound by buzzing, resonating, or = otherwise coloring the sound. I suspect that as a beginner you might = have a hard time perfecting those speakers if the original manufacturer = couldn=E2=80=99t do any better. I ended up with Linn Tukan speakers. Those were about $400 each, and = I=E2=80=99ve only ever heard good sounds come out of them. No resonances = or unwanted vibrations. That company really knows speakers. I have three = pair now (stereo plus surround). Another good option when I was on more of a budget was the Paradigm = Titan v5. I paid less than $200 a piece for those. Bigger, more bass, = maybe not as smooth as the Linn, though. I had four pair of these, but = three pair were stolen from a storage unit before I could build out my = next multichannel surround project.

The speakers are 380mm = tall. I believe that the resonant behavior is not determined by the = stand (the same thing is going on when I try them in a different room = with different stand). I believe that the resonance is related to a good = thing: these speakers don't have a scooped middle and have a healthy mid = range presence.
