My center speaker is LCR 6 B&W ,and one of the speakers in it blew.It was covered under warranty, but they said that I needed to get my receiver check out.It is Yamaha 2400 that it might be DC voltage leaking.I have all my speakers set to small,and no extra amps.Do you think this is anything to worry with or wait to see if the other one blows.How can you tell.THX
