20 Most Recent KLH PSW8100-8 Subwoofer Questions & Answers


If it has a 3 prong plug, try a 3 prong adaptor - where only 2 prongs are plugged in. Sub's should not be grounded. If it still makes a hum noise, the amp circuitry may be compromised. Replace the amp with an equal at www.partsexpress.com

Last two questions first - YES, use an RCA splitter to share sub line level out between two subs and use one at the subwoofer end to share that line with both inputs on the sub.

Either attachment scheme you describe would work.

Not being a big fan of conversion/deconversion for no real purpose, I would avoid stepping the high-level input down to line level for use by the sub's internal amp, run RCA to the sub(s) and keep them physically and electrically independent of anything else unless cable routing is facilitated somehow by daisy-chaining other speakers from the sub(s).

Dirty CDs and / or dirty optics. Clean all the CDs, buy a CD Optic Disk Cleaner, which has little brushes on it. Available at Walmart.

An interesting test would be to rearrange the disks so the three that play are next to the three that don't.
