The easiest way on how to check? Well, first thing dyan is the suspension. Press down on it -- if it's too soft then the suspension's loose. If it's too hard -- the suspension is still like brand new. However, if you're a newbie you'd have no way to know what "soft" and "hard" is without experience (it changes on a per-sub basis too).

Kung ganyan, just go for it. Just be extra sure to check the subwoofer's surround (yun rubber around the cone) if it is showing any signs of wear and tear like cracks, etc. That's usually the first thing that'll be worn down.
