Expertise needed - Swan speakers + Polk subwoofer to sound card, how to set up?

post #1 of 2
Thread Starter 
Hi everyone,

I have the Swan M200MkII's and a Polk PSW505 subwoofer. My computer has a Creative X-Fi Titanium Fatal1ity, and a Realtek onboard audio system.

I'm not really sure the best way to connect them to my computer...I know both cards have a single jack for Center/Subwoofer, but what happens when I don't have a Center with the Subwoofer?

Here are a few tests and results:
Connected to Realtek Onboard:

I changed the Speaker Configuration to 5.1 Speaker with Subwoofer On and other things off. When I test play, all the sounds except for the Subwoofer play through the Swan's, and the Subwoofer plays through the Subwoofer just fine. So this is great, except when I play any sound or music, I get no Subwoofer. This was tested with Pandora, Youtube Videos, games, music collection, etc. I'm not sure why the Subwoofer gets no sound?


Connected to X-Fi Titanium:

I connected the Swans to Green for Front Left/Front Left, and the Polk to the Orange Front Center/Subwoofer. I then changed the Speaker Configuration to 5.1 since that's what it Auto Detected. When I tested the channels, I could only hear the Front Left, Front Right, and Subwoofer (as expected). But unlike in Realtek, I can't seem to combine the channels of all the speakers into the FL/FR and keep the Subwoofer as is.

What should I do?

Can I put a 3.5mm splitter into the FL/FR of the X-Fi, and run both the Swans and the Polk off the splitter?

Thanks all!

Great choice of speakers – I have the Swans’ too, and they’re awesome!

Assuming you have only one pair of Swans’, I don’t know why you would set the soundcard to 5.1? I’d suggest just setting the card to two-channel, if that’s an option, and split the front L/R output (with the splitters you mentioned) to feed both the Swans and the Polk.

This runs the Swans full range, but that isn’t a problem. Since they have their own amplification they can’t be overdriven and blown, as you might have using small speakers with a high-powered AVR.

For the Polk sub, adjust its crossover setting for a good blend, probably somewhere in the 90-100 Hz range.
