I have de surround fps1000 4.1 (cambridge sound works), the subwoofer sound bad, the speaker its ok, but when i the volume up, the woofer sound distorsion. What can i do? Do you have or know how i can get the diagram circuit? Best regards
I had a problem closely with my FPS 1000 4.1 sound works four point surrond : my subwoofer sounds a metallic noise when the bass are loud. Maybe it is the same problem ? :
It were vibrations that go through the subwoofer and cause the noise.
Check the four screw well (the four hole on the back of the subwoofer). Put your finger on them to clog them and hear if your problem is solved. If yes, put scotch on them.
Secondly (i think you have disassemble your subwoofer), you can put silicon joincture on the box near the circuit, under the translucides cables. (the box where there are the plugs). >> if there are any hole between his box and the speaker, there will be some metallic noise (vibrations trough the box and the back plugs).

I have the same problem with my Cambridge Soundworks CSW250. Also one of the speakers doesn't work all the time. I'm sure it's a loose connection on the circuit board. When I tap the subwoofer near the connections, the popping noise changes (gets worse, better, other speaker works,etc.).I tried taking the subwoofer apart, but the area near the connections is sealed with glue, so I cannot access it. I hate it because when it works,it sounds so good. Anyone know how to get just the circuit board and back panel?
Most computer speakers are (SHIELDED) and this protects electronics from the magnets in the speakers! So you should be safe if your surround sound system is made for a computer system! ( if not two feet is a safe distance)
PLEASE rate my response to your question
The 'Subwoofer' output on your receiver is used to connect to a powered subwoofer with a built in amplifier. Your KLH speakers use what is called a 'passive' subwoofer, it gets its power from the receiver and then passes the higher frequencies to the left and right front speakers after taking out the low frequencies for the subwoofer. A speaker system with a passive subwoofer is good for casual listening, but a powered subwoofer is required for really hearing low frequencies and rumble in movies. The KLH speakers you have were highly rated in their time for their price. The four satellite speakers and center channel speaker have very good sound compared to the little 'midget' surround sound speakers most people buy today.
Here's how you hook them up:
- The left and right front channels from your receiver terminals should go to the terminals on the subwoofer marked 'From Amplifier'
- Your left and right front speakers are then connected to the subwoofer terminals marked 'To Speakers', they do not connect directly to your receiver.
- Your center speaker is connected to your receiver terminals marked 'Center'
- Your rear speakers are connected to your receiver terminals marked 'Surround'
That should get you up and running. If the bass isn't good enough with the passive subwoofer, you can get a decent powered subwoofer like the Velodyne VX-10 for about $150 and 'kick it up a notch'. Good luck and enjoy....
