I want to build a speaker cabinet, it will be my first one. I want to build it using only hand tools. I have figured out most of the issues in my head, but the one I'm stuck on is how to do the cut out for the speaker in the baffle. For no good reason, just some kind of gut thing, I want to use a flexible baffle. It's only a single 10" cutout so not as bad as a twin design, etc. I remember learning to use something like this in Wood Shop (a long, long time ago) Is this the answer? I can't imagine that it takes a very aggressive blade. Ideas?
