I have to concur with Keis. I rolled my own speakers 3 or 4 times, the first 30 years ago and the last (subwoofers) about 10 years ago. I have a full woodworking/metal shop, and a complete electronics shop, plus even better at work. I still have a hard time matching even the lowest grade finish and sound: I just don't have the jigs, etc., plus no test chamber, no good mikes, no experienced listener for 2nd opinions. If you wnat to make your own, do it because it's fun, a lot of learning, but it's hard to get really good sound. Try Speakerbuilder (AudioAmateur) for plans or books. Look at Madisound for kits or drivers. BTW, all homemade speakers sound teriffic to the builder. Good luck, Rich.
