The speaker plays, but is heating up the channel it is on. This occurs till the amp (Bryston 4BST) shuts off. After it happened once, I carefully monitored the amp. That channel showing the clipping light; I thought the amp was bad. I took it off and hooked up a Adcom 555. The speaker played at for a few minutes, then blew a fuse in the 555. The other amp hooked up to the Hales R2s since, has been rocking along great. Speaker problem, all drivers seem to play, so I suppect a x-over short.
Update on service question: QSC refers you to Madisound.com which the guy there is very helpful. They have the speakers and componets. It appears that I can have the speaker fixed.
Alittle time on the soapbox: I am very disappointed in Hales, I came down to my purchasing decision and bought Hales over PSB. I did think about buying American and believe in Paul Hales and Hales as a company. Oh well, nice speakers, but the company pulled the carpet out from under me. I hope they got fat, off that deal.
Anyway, Madisound seems to be the answer to Hales problems. Good luck.LR
