I doubt my a/d/s 312RS's will be goin anywhere any time soon, at $300 a piece I plan on getting a lot of use out of them... more then the 7 yrs I've had so far.
But whats this about being careful with aluminum cones? Are they fragile?
the 312rs' have "spun aluminum cones" if i remember right. Welded to the aluminum formers.
