[QUOTE="audioholic, post: 7254750, member: 549629"] 'Single spider subs' are fine, its all about getting the compliance the speaker designer wants. If the guy who designed your armageddon would have used multiple softer spiders, to achieve the same over all compliance, sag would have had the same potential to occur. Spiders have 'memory', they are designed to deform during excursion, and still return to their former shape. It would take a long time for just the weight of the cone/coil to permanently deteriorate that memory and cause sag. In other words, for all we know, your armageddon started sagging because you were over-driving the sub past its mechanical limits regularly. [/QUOTE]
