edster00 Posted February 25, 2002 Share Posted February 25, 2002 I'd try to isolate the ground...use one of those 3 prong to 2 prong adapters. It worked for a sub I have that has a 60Hz hummmmmmm. Quote Link to comment Share on other sites More sharing options...
TheEAR Posted February 25, 2002 Share Posted February 25, 2002 edster00, You are funny... HOW DO YOU WANT TO ELIMINATE THE KSW12's BUZZ BY USING A THREE TO TWO PRONG ADAPTOR? THE KSW12 does not have any ground.Its a two prong plug Now with my Sunfire and other big subs I have this is a great idea.And I use it,its A OK randog, Use a inexpensive power conditioner,better shielded sub cable.I fixed my KSW12 and 15 buzz by using an APC PC surge protector with a filter,and good quality UltraLink sub interconects.My buzz is gone. Hope it helps TheEAR(s) Now theears Quote Link to comment Share on other sites More sharing options...

MagnumMan Posted March 3, 2002 Share Posted March 3, 2002 randog, a friend of mine recently ahd his sub start humming. Even without the inputs connected,it started as soon as it was plugged in. He called Tech Support, and was told that it was probably due to a screw that might have came loose inside. He gave my friend directions on how to take it apart and fix. He did so and it fixed the hum,but then discovered that the amp was fried. So best bet would be call Tech and explain problem and maybe they can help. ------------------ Jerry CP RULZ ------------ Mains: KG 5.5 Rears: KG 3.5 Center: KLF-C7 Subs: (2) Antique wooden coffins with (3) 12" Advents in each Receiver: HK AVR-80 DD Processor: HK ADP-303 DTS Processor: Rotel RDA 985 AudioControl Phase Coupled Activator Series Three DVD: Toshiba 4109X Laserdisc: Yamaha CDV-W901 5 CH Amp(for subs): Rotel RB-985 Single Cass Deck: HK TD-420 Dual Cass Deck: HK DC-520 Quote Link to comment Share on other sites More sharing options...

Goon Posted March 4, 2002 Share Posted March 4, 2002 I had a humm when I connected my new Sunfire recently. Mine was due to a ground problem in my cable line coming in from the outside. I was told this is a fairly common cause of subwoofer hum because the cable lines coming in from outside are often not grounded correctly. The fix was a $2.00 ground loop isolator from radio shack, and about 20 minutes of my time. Worked great and completely eliminated my hum. Might want to give that a try.
