I have a Yamaha RX-V361 hooked to my HP computer with Klipsch Pro Media speakers,front ,center and rear channels, with a Polk Audio sub woofer. The problem I have is no bass response. I also have an RCA Pro sub that I hooked to it and still have no bass. The RCA Pro sub will rattle the house hooked up in my den on that system, but has very little bass response on my computer set up. Any suggestions on what I can do, or what I have done wrong? Any help would be greatly appreciated. Thanks..
 
I would say check the crossover settings on the woofers if they are powered but since you said you tried a second woofer and its the same problem, i'm going to lean towards maybe a setting on the receiver itself. I know on my denon, buried way deep in the menu layout there are settings for the subwoofer crossover freq, and sub-level.

We could probably help diagnose the problem a little better if we knew what type of sub woofer the Polk is.
 
how is it hooked up, via analog cables or hdmi/spdif?

If analog, look for LFE crossover settings in your sound card driver. If digital, then look for LFE crossover settings in the receiver.

Also, that will only apply to audio without an LFE channel. Play a movie with 5.1 audio, and the subwoofer should work even without the crossover being set up.
 
is the sub putting out anything at all?it could be crossover,or level settings.if nothing is coming out the sub out on the receiver may be disabled.
 
Start at the source, make sure any software EQ or effects are disabled in your sound device's control panel. Set the reciever for "straight" on the input for your PC. Use your remote and enter the Speaker setup menu (setup button), your sub out crossover setting is there. Adjust it up or down with some music playing (or whatever sound source you prefer). Mine was set to 80hz factory default. You can also increase the signal level to the sub in the "level" menu part of teh setup menu.

You can try reversing phase also, though I doubt that would account for lack of response.

Some subs require a better cable as well, I use a digital grade RCA cable, the same you would use for digital coax to the reciever.

I have a RX-V371 connected with Toslink and have plenty of bass response.
 
one more thing.its also possible your mains are just overpowering the sub.if so the only real fix for that is a more powerful sub.
 
Hey I'm trying some of all these suggestions, will let you know what happens, Thanks.
 
Well, I tried and still no thumping bass from sub woofer. When I go into the menu on the Yamaha remote and check each speaker, the sub does have sound and it rumbles. when playing a music video or watching a movie, I don't get the bass response that I should. I've changed the crossover point, set the front center and rear speakers to a lower level, and nothing seems to help. The Polk Audio sub is PSW 110, the RCA Pro sub has a 200 watt amp, and it does kick ass on my Sony receiver I have in the den, but if I put it in my computer room on the Yamaha hooked to the computer it has no bass, What is my problem here, if anyone knows, please help.
 
most likley you need to have the bass of the speaker channels sound fold into the subwoofer on your reciever side. your reciever is probably set to only send the .1 channel to the sub. have you tried the speaker tester in windows?
 
What is your sound device on the PC? Have you updated the drivers? How is it connected to the reciever? If the sub works right with the internal self test on the receiver, it's the signal coming from the PC that's the problem.
 
on your reciever, make sure your speakers type is set to "small" and not large. Large setting on most receivers means that all sound is sent to them and the sub doesnt get used. This might be your problem.

This. Sounds like the problem is coming from the PC. What speaker settings do you have in Windows? Are you using a soundcard or onboard?

your both subs suck. You're going to need to get a bigger sub. How big is the room?

That may be true, but is pretty much irrelevant if he isn't getting any sound at all out of them when they work fine on other systems or on self-tests.
