Not sure, I've found brand new computer/Server cases, a computer with an athlon 64 and 200gb hd working... list goes on.... but i think your right in this case, i found the receiver as well which did not work when plugged in. This set is 110 only and as we are in germany, i dont think they knew about the voltage and blew it. I really could use an amp for this sub, was going to use an old Sansui amp that i found but it really screwed up. Anyone know where i could get a good cheep 50w 8 ohm amp from?
