Hi all.  I am looking for a PDF copy of the KSW-200 subwoofer service manual with schematics.  Does any of you have it?  Thank you.

 

 

Do you have the schematics for Klipsch SPL120 subwoofer?

Have a 50-60Hz hum/buzz in your system ? Its likely a ground loop issue and luckily there are ways to combat the issue.

 

Feel free to make this a sticky as the issue is common and not just related to subwoofers.

My Klipsch SPL120 subwoofer generates hum too!  I bought an isolation transformer. It didn’t remove the hum.

Google is your friend is what I used to tell everyone. 
Goodluck!

Thank you.

I always search the internet (Google, You Tube, etc.) before turning to this forum for answers.  This forum is my last resort.

My home theatre in our basement has 7.1 speaker setup.  Sights and sounds are superb when watching movies.  I could hear sounds coming from all 8 speakers, including the subwoofer.

However, when I play music (phono, music CD, iPhone music via bluetooth, internet radio and FM radio) the sound system switches to stereo mode, and the subwoofer does not participate.

 

How can I make the SPL120 subwoofer participate with the stereo sound?

 

BTW, I have a Yamaha Stereo Network Receiver  R-N303 setup in our master bedroom.  The subwoofer works with the other two speakers.
