You're so right. Most people who would like to build a speaker kit are turned off by the challenge of cutting all the panels to the right width so they'll fit together reasonably well. Bob Brines told me about the mdf boards, which he tells me are also available in 16" width from some sources. Even if you have a good table saw like the Delta Commercial model I use it's still so much easier to trim a 12" or 16" pre cut board to the right width than to lift a heavy 4'X 8' mdf sheet onto the roller table and run it thru the saw. I like the idea of the laminated pine - that would look really nice with just a coat of varnish.
