Regarding crossover mods, I'm also curious if people are modding them inside the cabinets, or if you're able to remove them from cabs. I've opened mine up a couple times and don't see how the crossovers are attached internally, assuming some kind of glue, and not wanting to start trying to force anything in there. Is there a trick to it, or do you just have to be really agile inside there with your soldering iron?
