Question about Sony SA-WM200 Subwoofer

1 Answer

My sub has stopped working. It worked fine for the 3 years i've had it; then nothing. I have never touched the CUT OFF FREQ or PHASE and theVOL has always been at 50%. I connect it to my Yamaha RX-V730 receiver with the single conn to the recs SUB WOOFER jack. i tried all the usual "check connnections' stuff. nothing. ant ideas?

    I apologize for my lack of clarity. Stopped working means sound stopped comming out of it. That's it. The little green light for power still works, so electricity is getting at least that far. The receiver is a Yamaha RX-V730. I've never had a problem with it. The connection is the standard single RCA line that plugs int the rec's SUB WOOF OUT jack. I took the back off of the sub and found a small cylindrical fuse that appears to be fine. Thank you for responding to me. We don't know each other which means you are a considerate person. Kevin

    Stopped working? What's that mean? Does it light up? Make any sounds at all? It helps immensely to know what DOES work. "It's broke" isn't helpful. Do you know if it's dead or is not getting an input? Not knowing your receiver or attachment details its impossible to go further. This could simply be a case of a wrong setting or subwoofer output RCA cable bad. Need to know more.

We're talking Sony SA-WM200 Sub, right?

OK, now we go through the usual drill.

Does it work during speaker setup?

Yes? Not broken. Redefine the failure mode and start over.

No? Is it defined to the receiver?

Yes? Are you sure the RCA cable is ok? Try another.

Still unresolved?

Let's prove it's getting an input. Move the cable from the Sub Woofer Out to either channel of the Main Output (below the speaker connectors) and choose FM as the source. This would eliminate direct a Front Channel signal to the sub, bypassing the internal dependency of directing only LFE to the sub. Granted, there may not be much low bass in the program but a working sub will reproduce something in the presence of full-range signal. You may have to actually touch the driver to feel it moving.

Still nothing?

Then we're doing forensics.


Did it just stop working while you weren't looking or was there something traumatic that preceded it?

Disconnect the power to the sub. If you can access the actual terminals on the back of the speaker driver you could disconnect them and attach speaker leads from, say, your front right speaker, to see if the driver is alive. Or, if you have an ohmmeter, just measure across the terminals. You should have some kind of low single-digit reading but not a dead short. If the driver is ok that would point to an internal amp problem. Too bad. A pro needs to look at it.

I had a Klipsch sub amp die on me and the local guru couldn't do anything with it so I disconnected driver from the amp, ran some cables outside the enclosure from it and got a separate amp to push it. So it's not a total loss.

Do you have the subwoofer amp connected to the pioneer thru pre amp connections; pre amp output of pioneer to pre amp input of Kicker amp.

You can select the cutoff freq. that will pass to the subwoofer; The slopes don't match perfectly, but if you use the -12 slope , it should work fine.

Hi! I have purchased a JAMO S608 HCS 3 and a SUB 650 using an OKYO TX-SR508 Receiver. I can't set it up correctly. When I played music I've heard a lot of bass, I think there are some high...


The TX has speaker setup and test tones for setting the balance and distance with test tones and proving the hardware works. If that all works the difference is probably external or settings.

What is different between the music source(s) audio and the HD movie source(s) audio? Ask yourself, how would a sub make high frequencies go missing? It can't.


Your other speakers are responsible for conveying the high frequencies.

The manual is here...

http://www.pioneerprodj.eu/eur/products/42/99/S-21W/media.html

Flashing Blue is not defined in the manual.

Have you tried changing the Auto Standby switch to ON?

You can prove if the sub amp will respond to a known good input by TURNING ITS VOLUME DOWN tp start and just feeding it ANY RCA output from the receiver while playing, say, FM (to keep it simple). That way you would known in which direction the problem actually lies (internal or external).

try testing the amp without speakers plugged in. Run the sub preamp out to the amp that you will drive the subs with, but don't wire up the subs yet. Test for protect mode kicking in.
Yes - unplug the rca ins from the amp. retest.
No - Problem lies within the sub wiring. What is the load on the amp (measure with an ohm meter)? If it is below 4ohms, chances are the amp can't dip that low. Give it more resistance by wiring it differently (series vs. parallel)

How conect one subwofeer 12


The sub woofer can be connected by bridging one side of the right channel to the other side of the left channel. Usually this will be marked on the speaker connection terminal and use will not have any trouble to locate. If not use the + ve of the right and the - ve of the left to connect to the sub woofer. turn it on and check . If you find the phase different- with less bass- reverse the connection and try. this will work fine. Good day
