LSiFX Sound Test

kmartin971

During a sound test my left surround seems to create a hissing sound while the other surround gives the same response hear thru all other speakers. I chcked all wires. I then removed the jumper and tested each connection. the woofer does not appear to giving a mid range response.

Also, hooked each speaker up to a second receiver and same speaker does not seem to have any mid range?

Any have any idea what the problem is?
