JL Audio 10w3v2's Trouble

GuysI purchased a JL Audio ProWedge enclosure with two 10wv2's.  I have a JL 500/1 monoblock powering them.  I am very pissed!  The left sub stopped firing some time ago.  So being I purchased the equipment from an authorized JL Audio dealer, it was under warranty.  The dealer was very helpful and had given me a new out of the box loaner until JL sent me a new one.  Well guess what happened.  The loaner speaker quit!  Everything was hooked up by the dealer and appears to be ok.  The amp's settings were tweaked by myself and a JL rep via email.  So I do not believe those subs blown from abuse.  When the dealer checked the first one he stated that it was just a fluke and said he'd waive shipping costs because he also thought that it wasn't blown from abuse.  It's very ironic that the speaker that keeps quitting is the left one.  Why?!  I had invested hard earned money!  I didn't contact the dealer yet being that it is Sunday.  But I'll be willing to bet he will either replace this one, again, or say it's all my fault.  If he replaces it,  I'll be left in the same position, subs working, but for how long?  Is there anyway I can get a different sub(s) in place without forking out more money?  HELP!!!!!!!!!!!!Tony
