Question about Speakers & Subwoofers
Canton AS 105 SC subwoofer
age 18 mths
root cause unknown assume teenager use in playing ''loud'' music
Most AV receivers do not have a built in amplifier block to drive a subwoofer, and merely provide the subwoofer output channel at line voltage. Thus, a powered subwoofer is required. Does the subwoofer require mains power? From your description, I'm guessing it doesn't. If not, it does not have a buit in amplifier, you will need to purchase a monoblock amplifier, which is just a mono amplifier with a volume control, no tone controls or anything else. Make sure that the amplifier power rating is as close as possible to the subwoofer power rating, as it is quite possible to blow a speaker by using an amplifier whose power output is too low, by overdriving the amplifier , and putting DC through the voice coil when the amplifier clips. If it does require mains power, it will have an amplifier built in, but does not have line level inputs.

no jack =no sub audio signal so you would have to get some kind of summing filter. this would sum (mix) the two signals together and extract the sub audio from both channels in order to drive the powered sub woofer you have. could be expensive dont know.

Well, so far so good. I reinstalled the newly repaired amp and fired it up and so far, so good. Ran it through about an hour of fairly intense break-in tracks and then ran it through about 2 dozen power up and down cycles to try to get it to fail (better now than a month from now and have to fight them on backing it up).

Dont remember which cap it is , but its 47 uf 35v, on one corner of the board. You can use a slightly bigger value and slightly higher voltage if thats all you can find. Check the two caps next to the voltage regulators, these go as well problem sorted!!!!
