Braidkid,

Yes the mains were off. I became suspicious when I was playing around with Scott's suggestion to implement the subwoofer's internal crossover as a fix to the full range analog signal. My irk was that I would have to flip the switch on the Sub everytime I changed input because the digital ones supposedly worked. As intended, the Sub's crossover limited the bass response on analog sources. But I still did not want to keep switching the sub so I consigned myself to running digital out on my pioneer and using that as my CD transport until the fix comes.

Lo and behold! Engaging the crossover on the Sub with the now digital signal produced the same results...dramatically cut (and now normal) bass response from the sub. That is when I unplugged the mains and broke out the RTA for confirmation.

If yours work, great. I don't think mine do.
