Question

Need help with a subwoofer and receiver.

Sep 3, 2014 12:47PM PDT

I found a Panasonic subwoofer (sb-wa830) with power cable ONLY that someone threw out. There was no receiver with it either.

It appears to be in great condition. It does not have the cable that connects it to its compatible Panasonic receiver.

How can I connect it to my Sony receiver (STR-DH130)?

What gets connected to what? Do I need that missing subwoofer cable? Or can I rig something up?

and maybe there is a good reason...

for threw it out. This looks like part of a home theater sound system. My suggestion is either try to get a schematic diagram of the HT system or open the thing up to see what's in there. Good luck.

Oh...your Sony is only a stereo and if you want a sub. this sub will need to be special, I don't think they build them anymore.

I may give it a try one of these day. I do own one of those old speaker system for stereo receiver where it has its special designed filtering system.

Subwoofer Hooked to Sony Speaker Connections

Pepe7,

Thanks - I'll get some connections and give it a try. May take a few days to get to the store, but I'll let you know how it worked. Seems rather easy to do, too.

Thanks,

You misread what is posted here

Pull up a chair, slow down and start over.

Your subwoofer is NOT a real sub (=separate component with more universal compatibility with receivers). It is (was) part of an all-in-one proprietary system, hence it's not to be used here.

The above link I added refers to the added compatibility in some cases of a *traditional* sub, not the one you found.

Not gonna work

Understand, what you acquired is part of an all in one system and not intended on being used like a standard sub you purchase on its own. What you do *not* want to do is use something that could possibly (not necessarily though) damage your Sony receiver.

You can find a sub for $100 or less if you look around. Used audio shops can be really amazing(!)

Workaround

I'm going to necro this thread in case the OP still has the little sub.

I found one of these in a free pile approximately 3 months ago. I'm finally getting around to taking a look at it. Here's my solution for using this subwoofer without it's intended proprietary system:

First I removed the panel on the back of the unit. This exposes the electronics and you can clearly see the speaker cables plugged into the board then going up into a sealed part of the enclosure where the speakers are installed.

I'm going to wire up the speakers directly to the "B" channel of my amp. If it doesn't sound desireable, I'll purchase an inexpensive passive crossover to filter out the frequencies I don't want going to the sub. Done. Nearly free subwoofer.

Extra credit:

If you want to make the unit lighter in weight, pull the electronics out and reinstall the plastic plate. Send the electronics off to an e-cycler so they can make use of components and keep them out of the landfill.

If you want to get fancy you can install speaker terminals somewhere on the plastic panel at the back of the box, making it easier to connect/disconnect your cables.

Have fun hacking!
