Not that it would help.

Is the white noise present in the absence of an input connection, free-floating?

The amps in both of them sound like they

My CHT-8 powers on but doesn't have sound.


Check your receiver's speaker set up menu and make sure suboofer output is set to ON.

Clicking noise from sub when in standby mode


Disconnect the input. Does it stop? If yes...

It sounds like it's sensing a signal at its turn-on threshold. Figure out why there's signal present when it shouldn't be there.

Exactly how is it connected to the source? LFE-only or full-range signal?

Sub has started humming with amp turned off. just turned on at wall switch.nothing running


If the hum is from the back of the unit around the amplifier, it may be the transformer. It could be that the mounting is loose.
It could also be that the transformer is going out.

Disconnect all the inputs to the unit, Still hum?

If the hum stops you have something causing noise to the input.

If you have it on a switched circuit, try moving the power plug to a different outlet that is not on a switch. If hum stops, then you have something on that circuit causing the problem

if all inputs are disconnected and it still humms good chance it is the transformer.

I hear some noise coming out from the woofer of CHT-12R


It very well could be the spaker leads hitting the speaker cone.

You could check this by removing the amp section from the back.
Remove the screws at the very edge of the amp panel.
