Klh subwoofer asw80-80

Lite switch turn on causing speaker pop. is there a muting circuit problem?
can it be fixed?

  • perky1 Mar 08, 2008

    renosean: It is a light switch, replaced all ground wires with no help. The oil burner in the kitchen is by far the worst at causing the woofers to pop and it turns them on. Added monster subwoofer unit to protect surges on elec. and cables, nothing seems to help stop this.

    When you say light switch are you refering to a wall switch or a lighting control switch?

Unfortunatly it is due to the wiring within the house. Short of buying an apc back up which will regulate the power there is not a powerstrip that will stop this. I used to have the same problem

Klh powered subwoofer model ASW10-120B... when you plug in to power... it makes a loud buzzing/humming noise

I would check the caps on the power supply. They are rather large electrolytic capacitors that will look like they burst and/or leaking. When these die, the caps ground and the sub will make a loud buzzing sound. If you are handy with a soldering iron you can replace them yourself. Replace them with the same voltage or a little bigger and same with the size.

If the cap. says 16v 4700pF on it, for example, a 20v 5300pF or a 16v 6200mF cap. will work for this application.

KLH ASW8 Powered subwoofer keeps blowing 3A-250V fuses

The transistors at the output stage of the sub amplifier circuit might be shorted so each time you power on, the circuit draws a very high amount of current which causes the fuse to blow. It's definitely a problem with the circuit so using a higher current rated fuse would probably just result in damaging the amp even more. You should ask a qualified electronics technician to take a look at it. I hope you can fix it.

I have a KLH ASW10-125C Subwoofer and a Harman Kardon AVR 3600 receiver. What should the setting be for volume, phase and crossover frequency?

Home Theater

volume - personal taste - usually just high enough that you notice the bass - try turning down until you don't notice it then turn up one notch in the switch

phase - depends on distance from other speakers - try initially setting to 0 degrees

cross-over frequency - depends on your other speakers - try setting at 60-100Hz

KLH ASW10-120B subwoofer

I realize that this is an old problem, but folks are still finding it on searches, so here goes.

Here are the two pages of schematics from KLH. I wrote to their tech department and explicitly asked for permission to share them here.

Here's the lower board, which has the power supply:

Here's the upper board:

Thumping Subwoofer

Ive seen this problem in alot of audio setups in vehicles but most peeps dont know this is not a good thing and will cause damage to your woofers or amp. 99% of the time it turns out to be as you said that bad boy muting circuit. alot of these curcuits do use separate transitors or diodes as mute switches but most of them are directly from the Microproccessor. Only way to trouble shoot this is with a schematic and a good car stereo tech. Good luck
