Distortion in the woofers

(1/2) > >>

oguinn:
Today in the right channel I started noticing some distortion in the woofers. At first I chalked it up to a scratched record but I noticed it happened on all inputs.

Here's what I've done so far:

* Removed the Kaiju, which would have normally driven the woofers, from the chain and drove with only the Stereomour II. The issue persisted.
* Tried multiple inputs. Issue persisted
Here's what I plan to try next:

* Once the BeePre tubes cool I plan to swap them. I anticipate this will not be the issue. (BeePre tube issue)
* Swap the crossover boards to see if the problem follows the board. (passive crossover issue)
* Swap the left and right cables to see if the issue follows the channel (BeePre construction issue/speaker issue)
Anything else I ought to try?

Updates as I get them. Here's what I've done so far:

* Removed the Kaiju, which would have normally driven the woofers, from the chain and drove with only the Stereomour II. The issue persisted.
* Tried multiple inputs. Issue persisted
* Swap the left and right cables to see if the issue follows the channel. It didn't. That, in my mind, eliminates the BeePre, the cables, and the tubes.

Swapped the crossover boards. Initially no change: distortion and weak output from the right channel. However, after a few seconds the sound kicked in fully without distortion.

This to me sounds like a loose connection inside the cabinet, which sucks since that means I have a new project. I'll wait until it acts up again.

Paul Birkeland:
When I have run into this with my Jagers, it has always been a loose banana plug (a loose set screw, not the connector itself).

oguinn:
I'm satisfied by that explanation for now. Saves me from light surgery.

Thanks, Paul.
