Possible Problem with SUB-12

[HAMP]

Hey Guys, I figured out the problem. You were right there is a malfunction issue here.
I’ll explain how I figured it out. I went to anther forum (Klipsch) and they really shoved it down my throat my set-up was in correct.

Someone made a statement of:
“ if the receiver is set to pass only 80 Hz (or lower) to the sub-12 then it should sound the same if the sub-12 is set to ANYTHING 80Hz or higher.“


I know that’s what you guys have been saying, but it had me thinking. I decided to turn the knob the other way. It sounded nearly the same or just a tad bit better, I know maybe more testing to really catch what’s been missing.

If you look at the dial, even if the number are reversed 80Hz would be 80Hz. 40Hz would be 120Hz and of course the 120Hz would really be 40Hz.

The dial does turn clockwise from left to right with the number starting from 40 – 120.

I’m thinking polarity might be reversed.

I decided to call Klipsch support and explain everything to them from all the forum info and testing. The Rep ask the S/N and found out that the subs were built around the same time from the same batch. They are in process of sending me two amps to replace inside my subs.

The Rep hasn’t decided if they want these two back for testing to find the problem or not.
