[QUOTE="Timber_MG, post: 18354, member: 18"] @ Ampdog. The force exerted on a cone is the vc/cone glue joint is B/L x the current in the voice coil (which is complex, but higher frequencies don't exert higher force than lower frequencies unless you investigate an axial resonant mode). The problem is if the glue softens (I assume an aluminium former is more prone to this) to the point that even these low forces work it free. @ Shonover: when properly designed (thinking of some old 8" Seas drivers here) it needn't be a problem. Target XO is 1k7-2k2. [/QUOTE]
