Subwoofer from the dump

Conrad Hoffman · 13th November 2011, 04:24 PM

I sure do love the dump, but sometimes I bring back more than I take! This last trip I scored a Kenwood SW-301 powered subwoofer. Now, most of my stuff is DIY, so I know little of commercial stuff. There doesn't seem to be much info on this thing on-line, though I did get a service flyer from Elektrotanya. Can anybody tell me if these were any good? I think it's about 15 years old. It seems to be in OK condition, except the former owner probably also owned a cat- the cloth is a bit messed up.

It's a 10" speaker with a 100 watt (peak) amp, nothing special.
If it sounds good to you, it is good.

Well, now I know why it probably went to the dump. When the circuit board that carries the rear terminals was wave flowed, the big pads didn't get hot enough and the solder never flowed to the traces. The thing lost contact and probably drove somebody nuts for a while. A good hot iron took care of it. Unfortunately the remote control never made it to the dump, so I'll probably have to hard wire some switches to the outside world so I can control the filter mode and polarity.

I picked up a nice little multi component Sony at a dump in Alice Springs, Australia, it worked fine once I put in the missing speaker wires.
I liked it so much I shipped it back to the USA, been my shop amp since 1996.

I should volunteer at the local electronics recycling depot.

BTW if you ever buy anything on eBay without a power cord, it probaby came from a local electronics recycling depot. The cut the cords off immediately as they accept the goods. Pretty dumb when you consider that re-use is the best recycling.

and I should add that I have bought quite a bit of stuff without power cords, for really cheap.

Sorry I can't tell you my favorite source...can't take the competition.

I checked in the Logitech harmony database and this amp is supported. A cheap harmony remote for $20 should be able to control it.

Thanks! The $5 one I got at Big Lots didn't.
