The description makes it sound like they fit. I was going to heatshrink the whole speaker holder with the battery housing and sound board. Not sure if the protection circuit would fit in there too or not. I figured I may have to move that further up the hilt. It is hard to imagine all this without parts in front you and no experience. That is for sure.
