I have 2 of these economy 10" subs, 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?
