[QUOTE="Djltoronto, post: 7135981, member: 628222"] I have 2 of [URL="http://www.kenwood.ca/Car_Entertainment/Subwoofers/10"]these economy 10" subs[/URL], and one of them makes a distinct "sound" when being played near it's limits. The 2 subs are in dedicated sealed chambers, 0.78 cu.ft each, running parallel of a mono amplifier, and when near it's mechanical limit, very clearly, one of them makes a difficult to describe sound, almost sounds like an amplifier clipping or like a mild bottoming out of the VC against the magnet - but that's not the case. I pulled the sub out of the box and noticed that the spider is essentially defective and has a "soft spot" near the VC.. (if a picture is worth a 1000 words, hopefully this video will explain what I am trying to describe). As I press on the cone lightly with gradually increasing force, there is a point where the suspension just falls a few MM's (as the spider essentially folds - see vid). I am virtually positive this is causing the abnormal sound when played at high levels. Is this fixable? or simply not worth it cause it's a cheapy sub? Click for video: See second Roll/fold on spider from the voice coil.
