All that said, I could not pass up what looked like a possible solution, even if it meant doing a little “hacking” to make the subwoofer independent of the missing speakers and controls. Altec Lansing VS4121 Computer Speaker 2.1 Subwoofer Sound System Complete WORKS. I really, really wanted a powered subwoofer, but was not going to spend a ton of money on one.

I already had all the speakers I needed for it, but that model Pioneer receiver/amp does not provide direct power for a subwoofer - it only has a dedicated “line level” subwoofer signal via an RCA-type jack on the rear panel. I had been watching for an affordably priced (okay, “cheap”) powered subwoofer to use with a Pioneer surround-sound receiver with Dolby 5.1 Digital processing and digital fiber optic inputs and outputs which I had purchased at that same Goodwill store for only $15.91 (knowing it most likely needed some sort of repair, given the el-cheapo price, plus it was missing the very specialized remote control.) I repaired the Pioneer audio processor/surround sound receiver at a cost of about thirty cents (the cost of a voltage regulator IC) and had purchased a factory remote on eBay for about $20. I do love discovering the occasional project item at Goodwill or other thrift stores, etc.īecause the two external speakers (left and right) were missing therefore, there were no controls to turn the subwoofer and its internal amplifier on or off or make any level adjustments at the subwoofer because those are actually located one of the two external speakers.
