I recently bought a new set of towers (above) and I'm having troubles. I'm not sure if its the speakers, receiver, or wiring. Some songs play and sound flawless and others sound crackly and distorted. I sat on the remote once and the receiver volume shot up with a quickness, however, I don't believe I damaged the speakers. It played for roughly 3-5 seconds and was nearly ear bleeding! Anyways, I have a Yamaha V367 and I'm not sure where to set the crossover and worried about the new speakers. Any ideas what would cause the crackling and distorting sound? I have (I believe) heard them in the rears which are klipsch bookshelfs as well
