[QUOTE="Art Welter, post: 122404, member: 52"] Re: matching amp with speakers Don, This is the second time you have mentioned that statistic in this thread. Back in the "olden days" of no HP filters or limiters, my experience was far more burnt coils than mechanical damage, even though the drivers were frequently driven hard below Fb. The rising impedance below Fb coupled with less magnetic force available when driven beyond Xmax with progressively stiffer suspensions at excursions above Xmax led to few mechanical failures. What drivers are you basing a 10 (or 50) to 1 mechanical vs. thermal failure rate on? Got photos? Art [/QUOTE]
