Yes, checked that - if I manually turn on the sub and have a signal going in, I get extremely soft volume when it is turned up. Turning it down reduces it to silence.

I've eliminated the receiver as a problem. I ran a headphone->rca cable from a laptop headphone jack to the sub line level inputs and the lfe input. Neither caused the sub to turn on, but when I manually flip the Auto/On switch on the sub to On, the power led goes green and I can hear very muffled music... but it still doesn't have the normal intensity. Not even "ok" intensity, just barely audible. The side dial volume/gain is all the way up/clockwise. Turning it down reduces volume. I haven't tried high level inputs, but I can tonight.

Within the last month or so I noticed the bass seemed light. I took time this weekend to investigate and found it acting as described. It had worked pretty well for the ~3 years up to this point.

I have an RW 12 that will not power on when given a signal. I have tried line in and LFE inputs. If I flip the switch to On, the red led will go to green and I can barely make out the beat of the music, bit it isn't amplifying it. On the electronics board I don't see anything smoked, burnt or bulged. The main power board (120v in) gives 8.75 V out whether the led is red or green. I don't know if this is normal voltage. Any tips on what to investigate or replaced? It is beyond the two year warranty. Does Klipsch do mail-in repairs? I haven't called them yet. The power board is iNDiGO Canada 600130 rev a, lfe/low/high-level-in board is indigo 630130 rev 2, the board powering the speaker is indigo BASH 00-X0103-01. Thanks for any info you might have...
