I have been absent from this forum for quite a long time. I developed a problem with my AVS Titan subwoofer and found on the internet that this was discussed here a few years back. I am hoping to be able to contact one of the members that responded in that forum because he stated that Titan Speaker Co. provided him with a schematic. I contacted Titan and they were not able to help.
I another post I will let you know the old gear I am still using.
Thanks,
