I never even considered the concept of 2-channel bass... That's actually quite interesting. I will have to remember that if I ever upgrade to a proper A/V receiver instead of a home-theater in-a-box solution.
I'm guessing most video games just have the 1 channel though, so I should be ok...
Well, I did a couple things here...
Thank you to boosted1g for the Hz range, and the crossover information that does help with the practical usage end.
So what I did is connected the receiver's L/R speaker wire inputs directly to the sub, and the sub directly to the L/R speakers...
Honestly, I would give the Y-Splitter a shot. It might degrade the signal, but then again it might not.
Either way they run about 3-4 $ at a radioshack, and they have about a billion and a half other uses if it doesn't work out.
While I can't provide you with specific instructions, I know that I have had situations with my dual TV/monitor setup where I wanted to accomplish this.
I know that by right clicking the volume control in your notification bar (by the computer's clock) That you can click on playback devices...
I have a Sony 5.1 audio receiver (I don't have the model# handy)
This receiver has ONLY Speaker wire outs for the Left/Right, Center, Rear Left/Right AND Speaker wire outs for the Sub-woofer. (NO RCA)
As you can surely imagine, the sub-woofer than came with this system is pretty much garbage...
