RM7200 subwoofer quit

[jeanmarie 123]

Ive just had the system for a couple of weeks. I switched the system on last night, played a trance music with good bass at +5 volume, and in the middle of the tune the subwoofer quit.
I did a reset, I disconnected the system, reconnected after 20 minutes, subw still does not work. I can hear it play, however, if I put my ear against it, but very low. ANy idea what it is? Did the cone blow up? aren't there protection mechanisms built in?
Thanks

Hello Jean Marie
Thanks for contacting us. Here's a fool proof way to test to see if the sub-woofer is functioning, or not:
1). turn the volume all of the way down on the sub-woofer and remove all of the connecting cables/wires except the AC power cord.
2). find the right and left RCA cables that go from your DVD player to the receiver and remove them at the back of the receiver.
3). bring the DVD player over to the sub-woofer and provide AC power for the DVD player, then connect the right and left RCA cables from the DVD player to the corresponding right and left inputs on the sub-woofer.
4). begin playing any CD (not a DVD, but a CD) and turn the volume up slightly on the sub-woofer. There should be plenty of clean sounding bass with no bad noises. Let the CD play completely through and try stopping and starting the player.
Let me know the results.
Regards, Ken, Polk
