KLH ASW12-120 Subwoofer - Answered Questions & Fixed issues

Find the "Sub Out" connector on your TV. Likely an RCA jack. Run a cable from the TV to the Sub's Input and you're done. If your TV doesn't have a Sub Out then you might be out of luck.

hi,
If possible check the crossover circuit board. There will be two or more ICs ( integrated circuits). fast of all just replace all the ics in that board. That ics will be very cheep in price. after replacing those ics make a test. if then also the cracking sound hears then you have to check the components amplifier board.
ok

Or you could just write of the built-in amp, disconnect the sub from it and run the driver's leads outside the box, buy any decent amp, connect it to the LFE feed for inout and the bass driver for output and carry on.

That's what I did when a second copy of a powered sub died the same way the first one did.

Suspect an overload in either the power supply or main amp section. Chances are some kind of semi-conductor has gone gone short circuit. You might be able to spot it with either a crack or damage or signs of burning. If it is a transistor an Ohm Meter will show it up, as it will be just like you had touched the probes together, when touching two terminals with them.

Start by replacing ZD3 & ZD4, then see what happens!

There's an amp inside the unit, most likely the semicondutor that does all the work has failed in it.

the audio amplifier IC damaged replace him

I just found your question answering another.

disconnect offending unit. then play see if same response occurs on the alleged normal unit using the offending cable interchange cables see if you get same result. Means it's bench repair ,internal electronics require specialist equipment to locate the offending item.

You could check it by having the unit switched on a touching each of the pins of the device with an insulated tool. Making certain you don't short any of the pins together. You should hear a buzz on each channel. If you get nothing on the right then it could well have gone. However that is a lot of messing about, as the device can be purchased for around £12, it could be easier just to replace it and see if that cures it. After all it is the device that does most of the work, so the chances are it's gone!

If you can post a picture of the fuse it might help in tracking one down. However I should point out that fuses rarely blow on their own. And one blown is a sign of a serious overload, probably in the main amp or power supply section.

This is what is called a 'passive radiator'. It helps the bass response of the system. It is an adaptation of a bass reflex speaker enclosure. Try this link at wiki: Passive radiator speaker

That is sometimes called a "radiator". It's a speaker cone that moves opposite the main woofer and produces sound waves out of sync with the powered woofer. Very sophisticated piece of audio engineering intended to enhance bass response.

It could be an internal short in the amplifier board. What is the model number?
