Well, a couple of months ago I listened to a pair of Monitor Audio Gold GR-10 bookshelves at my friend's brother's place. When we sat down to do our "critical" listening (heh), he placed a pair of weights ontop of the speakers.

I'm wondering what everyone thinks about doing this. Is there much of a benefit in reducing cabinet resonance or something (???) when you add 10 or 20lbs of weight ontop of a CBM-170? Can it hurt anything? I remember seeing something about doing this with a SVS PB10-ISD to improve spectral decay or something, but that was awhile ago and only one review.

Any thoughts?
