THe problem is not in the speakers, the problem is in your amplifier.Most likely needs some sort of MUTE relay, or the mute relay it has is not working.
Also could be a faulty capacitor somewhere in the amplifier. The problem is definitely not your speakers.
If you have a separate amp and preamp, the preamp should be turned ON first, amp second. When turning off, amp off first, preamp off second.
