Add powered subwoofer as second subwoofer to existing PC / Logitech Z906 setup?

[King Mustard]

My setup:

• ASRock B550M Pro4 motherboard (manual)
• Logitech Surround Sound Speakers Z906 (manual)
• Wharfedale Diamond SW-150 powered subwoofer (manual)

The SW-150 is sitting in storage doing nothing, so I was hoping I could add it as a second subwoofer to my PC.

The Logitech system takes up all three of the audio jacks on the motherboard, so I don't think I'll be able to add the SW-150 without getting a soundcard with more jacks but assuming I did do that, do you think it's possible to have the Z906 and SW-150 working simultaneously?

Totally different subwoofer character, you'll need to time align and EQ the subwoofer so one isn't cancelling the other out, boosting the frequencies you want flattened out etc.

You need something like dual subwoofer EQ like SVS EQ1 or Minidsp, to time align them both and EQ the summed signal.

No, it would do more harm than good even if you were able to do it. The Z906 are designed in a way which its satellites sound good and balance with it's own sub; if you throw the SW-150 into the mix it would actually make it worse.

If you really want to make use of the SW-150, just getting a pair of (even the cheap 9.0 or the slightly more expensive 9.1) Wharfedale Diamond and hook it up with the SW150 and use it as that and it would sound infinitely better than the Z906.

I don't know what's the audio setup is like for your home, but if it was me I'd use the Z906 in my bedroom PC, and the 2.1 Wharfedale with the TV for the lounge with the game console/PC for example.

Granted onboard sound has improve quite a bit compare to the past, but if you just want to improve how your Z906 sound, it's still worth invest on a good discrete DAC/Soundcard and it will sound noticeably better than the motherboard onboard DAC.
