Now I've done it!!!!

Tonite I was having fun playing my Tyros 5. I was playing the concert organ in Organ World and got a little aggressive with the volume while playing Rule Britannia with the Tutti. I literally blew the back panel out of my KLH duel 15" speaker!! The actual speakers are undamaged..........only the back wood panel (which was only glued) came apart. These speakers are 12 years old so I'm not that disappointed. I will attempt to repair them but it might be time to replace them. I'm old school and know much more about conventional large speakers than the newer types. I know a lot of you gig with Bose systems but I am a home player. Any suggestions on which way to look?? I am used to large speakers staring me in the face!! Thanks. -charley
