LSiC Problem

All right folks, I am trying to figure out what happened to me LSiC...
Last night during the Toy Story 3 BR, listening at moderate to low volumes, there was VERY noticeable distortion during some very specific scenes. It was only there for those scenes.
The full background is that this was the original LSiC that I sent to the Skiing Ninja for cross-over mod work. It has an external cross-over. It is powered by an Outlaw 7700. I have not had any problems with it up to now. (Well, the last problem was due to the new inductor, which is now external, so that doesn't count
)
I am thinking it is either the low-end driver, or the portion of the cross-over dealing with said driver. THe reason I say this is I would think the mid-range and tweeter would be used almost 100% of the time on a center, but the low guy would only come in every so often. I think have it cross-over at 100 hz in the preamp.
So, how do I track down what is wrong, I am kind of new to the debugging a speaker problem scene...

Hello, Ted. Switch speakers only and see if it follows. Do not switch x-overs.~ In search of accurate reproduction of music. Real sound is my reference and while perfection may not be attainable? If I chase it, I might just catch excellence. ~

How? The wires from the cross-over to the speaker are soldered in. Are you saying inside the speakers, put the mid-driver wires on the low and vice-versa?
Or, move an LSi9 to LSiC duty...HT: Ninja Master LSi9s, Ninja Master LSiC, Slightly Modded LSiFXs, Modded LSi7s, Outlaw LFM-1 EX and Polk PSW125

Basically, it can't handle the 7.1 DTS-MA track yet. Oppo is working a firmware fix for it...HT: Ninja Master LSi9s, Ninja Master LSiC, Slightly Modded LSiFXs, Modded LSi7s, Outlaw LFM-1 EX and Polk PSW125
