Not that I've done tons of speaker swapping over the years but I've never run into a situation where the holes didn't line up and quite frankly it never occurred to me that it might be a problem. Guess I've been a bit lucky but I still imagine that most manufacturers would see the benefit of sticking to some sort of standard. Would you buy a guitar from a company that only worked with their proprietary cable/connector? I'm not against real innovation and change but if your going to reinvent the wheel just to force consumers into the box you've built I'll pass.
