Audiobahn AWT12X subwoofers. Bought these dirt cheap on ebay with burned voicecoils. Reconed both. Work as good as new. These babies have 4inch voicecoils. A guy on www.termpro.com forums plugged one into a 120VAC wall socket to kill it.... it lived! That's over 1800wrms before the 15A breaker blew. Hahaha. A single one of these takes all my 1000wrms amp has to offer. 40lbs each.... all motor. :-)
After reconing them I tested each one on my Technics home receiver (200wrms+) free-air!!! Didn't even hit excursion max.
