they are Arum Cantus speakers, Adcom amp and pre amp....a small not so
powerful system but ideally suited for my listening environment.....

no way should the displacement be that great on those woofers......even 3/4
inch would scare me on my Klipschs, and they have 12 in woofers....At any
rate, the Adcom should have some sort of a bass filter to moderate very low
bass, but it is odd that only the one CD copy gives you an issue. Good luck
on your quest, John.
