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?

This thread from another forum from 2014 implies it can be done:

adding a second subwoofer

i have a logitech z906 , and i want more bass . so can i split the subwoofer channel on my soundcard and then connect a 2nd sub to it with a 3.5 mm jack to red and white cable converter ?

but it wouldn’t be as a stereo subwoofer arrangement, it would be 2 subs connected to the 1 output

I'm ignorant about this, just curious about the objective—louder sound, broader coverage, what?

Just more bass 👍🏻

Perhaps investing in a discrete sound card would help. If your subwoofer isn't placed at the corner of a room whereby two walls intersect, that might be what's causing to a lack of bass. How large is your room?
