I have a full Paradigm HT setup; Mini Monitors and a cc-370 center and matching surrounds. All are the Monitor series and all were purchased at the same time. During a recent Avia calibration I noticed the center speaker was clearly high pitched than the fronts or surrounds. Is my center speaker bad (shouldn't it sound at least close to the fronts when playing white noise in a calibration?) The speaker has always seemed a bit high pitched and during some DVD's I'll hear a really high pitch hiss; I've always dealt with it because the hiss was only present in a few scenes of a few movies. Since I have moved to a new house and re-arranged my HT into a smaller room the pitch is more pronounced. Any thoughts? Is this normal? I suspect I'll be heading back to the dealer to compare my center w/ a 'known good'.
