[QUOTE="John_E_Janowitz, post: 6113235, member: 550657"] Just a quick note on papermaker's woofer that came in about 5min ago. I'll have pictures posted up shortly once i can get them off the camera. The cone is ridiculously bent up. The surround is torn off the cone at one point. The spider is not "worn out", it is actually torn halfway around on one side of the coil from being driven much too far. The only way for all of the above to happen is simply abuse. The driver has 23mm Xmax and about 30mm travel before the suspension can't physically go any farther. It is not meant to move farther than this. This is more than enough to get high levels of clean output for any SQ type application this woofer was designed for. If you plan to try to repeatedly drive the woofer past the physical limits, it can and will break. A subsonic filter is necessary in a vented box to prevent over excursion. That is what they are for. Also I feel the need to stress this again, there are reasons the woofer is rated at 1000W and not 1600W and not specifically intended for SPL application. John [/QUOTE]
