Logitech Z-5500 subwoofer + adapter

Greetings! My old 5.1 system is already 16 years old, and for the past ~5 years, I’ve been constantly repairing it at service centers.
Recently, the control panel (control pod?) broke again. And I guess it’s a time to let it go. But one thing I don't want letting go is the awesome Z-5500 subwoofer.

I recently purchased the Edifier MR4, and I’m really missing the bass that my 5.1 system (with a large subwoofer) provided. So, I want to pair my old but beloved subwoofer with my new budget monitors.

Question: If I purchase just this ☝️ adapter and connect my subwoofer directly to the motherboard (C-SUB) using it, will it work? Maybe someone already tested this adapter?
Edifier MR4, unfortunately, has NO subwoofer output.


Thanks!
