Yamaha SW118V Subwoofer

My SW118V Subwoofer is cutting off and on. I am using 2 Yamaha tops which has no problem. I switched the channels to make sure it wasn't my amp and the two tops plays with no problem. I also switched the cables on the speakers, but the subwoofer continued to cut in and out.

NICE SUB! I have found that when this happens, there is a good possiblity that there is a loose connection on the speaker, or on the crossover network inside the sub. The real only way to test this sub to see if it is indeed the sub, would be to test it in real time under controlled conditions. That would involve hooking the sub up to a power amp that has a tone generator attached to the input and driving the sub to its rated capacity. Other then that, you could probe around to see if you have or can see any loose connections inside the sub BUT I would not recommend you doing this while the amp is on as you could short out the output stage in the amp. My best advice would be to take or send this sub into an authorized Yamaha repair station. Good Luck

I have a yamaha nx sw150 subwoofer that i want to connect to a pioneer receiver vsx 1020 that has no system connector that the original yamaha receiver had,is it possible to connect the subwwofer to this...

Parts from all-in-one packages like this aren't inended to be pieced out to other applications. Proprietary connections are a huge clue and disincentive.

A look at other Fixya queries gives this answer:

"I have this sub. The system connector jack needs a 12V DC signal to turn on. If you don't have a suitable Yamaha receiver with this connection, use any 12 V DC adapter with a 1/8 in mono plug (the tip should be positive)."

I imagine the subwoofer could be opened up and whatever circuitry is enabled by the Control signal could simply be jumpered "true" so it is always ON. That would mean the amp would be drawing power at all times, though.

Hello ! I'm not sure how to connect my kef psw 2500 sub to my yamaha amp. I've got a subwoofer out on my amp but there's 4 inputs on the sub and I don't no which one to use ! Please help as getting...

Just for clarity, I need to explain what the four inputs are on the KEF subwoofer. There is a left and right RCA input which is the input signal to the subwoofer and there is a left and right RCA output which is the High Pass output from the subwoofer.

On the back of the Yamaha receiver, you said you have a subwoofer output. This output is most likely the mono subwoofer part of the home theater system and can be used if you like. The left right signal input into the KEF is summed into mono so if you only connect one channel you will basically reduce the signal level by 1/2 (-3dB) but it will work fine.

Alternatively, if your Yamaha receiver has monitor out and monitor in, you can run the monitor output signals to the subwoofer and you can then run the high pass outputs from the subwoofer back to the monitor in. This will give you the subwoofer and provide a smoother signal matching with your audio system.

It is not always easy to connect the subwoofer up to an integrated receiver/home cinema system using the high pass channels of the subwoofer as you don't always have access to the analog output and input of the front channels. In this case, just use the Subwoofer output or just the monitor out only.

I hope this solution is helpful.

My Yamaha SW118 keeps cutting out (volume reduces to v low level) even when driven by 500W amp. Doesn't seem to be the amp but not sure if the speaker has it's own internal protection. Can anyone advise?

Poly Switch
All full-range loudspeakers are fitted with a self-resetting
poly switch that protects the high-frequency driver from
damage caused by excessive power.
If a loudspeaker cabinet loses high-frequency output, immediately
remove power from the unit and wait for two to three
minutes. They should allow the poly switch to reset. Reapply
power and check the performance of the high-frequency
driver before continuing with the power reduced to a
level that does not cause the poly switch to interrupt the signal.
On the SW115V/SW118V/SW218V sub woofer, the Poly
Switch protects the woofer and a similar routine should be
followed if its output is lost.

Yamaha YST-SW320 subwoofer won't play sound

I too have amplifier and speakers thatI rent for parties, and sometimes when I connect them they don't work and I battle with them for hours before I find the out that its just a little thing that happened, like speaker wire might have cut inside, or the wire conneted for the CD to Amplifier is bad and son on.

But I will advice that you test your amplifier and woofer, with another equipment independently to be sure if they still working well or not. As this will help you to know what to do next.

May somthing happened to one of them the last time you used it and you did not notice, and it might just need some servicing.

Best wishes

Cerwin vega ht-10d subwoofer won't work in yamaha reciever

Well, as I know, your Cerwin Vega subwoofer is designed for use with stereo systems. Therefore, it has only 2 channels for input, and 2 channels for output as well. However, you can try this out; the first thing I suggest is that you hook up your main front channels through the subwoofer. All you have to do is to connect the subwoofer input to the front channel output on the amp, then hook up your front speakers to the satellite output on the subwoofer. As long as you make sure that system is working on 8 ohms, I believe this can activate the subwoofer.
