Auto set up on my onkyo sr602 will not read the klipsch ksw12 subwoofer, please help?

Question

front and rear speakers are polk rm2350. center is klipsch sc1 and surround speakers are klipsch ss1. sub cable is from preout sub and have tried cable to lfe R and with splitter to L & R on sub. Switched cable and made sure directional flow correct. Unplugged system and tried auto set up again. reset reciever to factory spec. no good. read the manual 10 times. Am a novice and not very tech inclined. Hooked a polk 10" sub and it worked, took the cable off and set the klipsch in its place and it worked. Cut it all off and went to bed and no bass when I got up the next morning. Hooked up a klh 12" will not read that. I'm about to the point of dropping it all and buying a $200 boxed system (not really) I have a mitsubishi 52725 52"Hd with only a coaxial digital to the reciever and a Dish HD DVR hoked with HDMI to the tv and Optical to the reciever. My email is [e-mail] and I really need some guidance on what it could be besides my lack of functioning brain tissue. THANKS

Answer 1

In some cases ( I can't understand why) you have to switch things on manually instead of using an automatic set up. I would try turning on the subwoofer output manually and see if it comes on, because the auto set up systems don't always work perfectly. BTW, some subwoofers require a higher signal level to turn on than others. This could also be the reason why the ONKYO didn't "notice" the Klipsch subwoofer. Good luck

Maybe the problem is not with your equipment or sub but with program material. You don't say what it works with and what don't work. Maybe the material you are playing lacks any bass therefore you sub is not playing.
Make sure your receiver and your sub are on, and try playing Cd's with a good amount of bass in the material, and see if the sub is playing, you may want to also play with the subs volume control just to make sure you can hear the sub playing. If it will play the Cd's fine then the problem is in your material or lack of bass material not the sub.
