I need Replacement Satellite Speakers for Logitech Z523 2.1 System

[N7eons]

i have Logitech SPEAKER SYSTEM Z523 http/ with faulty power switch/speakers volume potentiometer. When I turn power/volume, power light just blinks for moment and then turns off having no sound. When I return volume control back to the point of powering off, minimum volume, it start blinking again. I opened speaker and plan to spray a little with wd40 tomorow when I get it, but i think potentiometer died, so i will replace speakers and keep subwoofer. My Logitech speakers have volume and bass control but my subwoofer has no controls at all, I control it via speakers. All desktop speakers only have volume control or they are too expensive (they have built in bass). How to control my subwoofer with regular desktop speakers? I need buying advice. I could buy from here http/ for 20$ but I need something universal.

Do not use WD40!
Get the correct cleaner for volume potentiometers. As you say it may not help.
Since the sub is self powered you could connect it to the subwoofer out of the PC directly of it will turn on without being connected through the satellite speakers.
You might be able to bypass the control and use the PC to control overall volume.
