Having very slowly learned a little bit about a variety of subjects on this forum I wish to embark on a new sea of ignorance. I want to build a speaker cabinet and thought I would start with a simple one, the ubiquitous TL-606. I have been unable to find any plans other than the original EV one nor anyone who has tried to build a lighter version. So let me know if you are aware of a successful lighter version and what you think of my idea for a lighter version: Given that the original plan uses 3/4" plywood, I propose cutting the five sides (sixth is the baffle) out of 1/4" and 1/2" plywood, cutting a grid of 3" holes in the 1/2" with a hole saw, then gluing each perforated 1/2" panel to the respective 1/4" panel. The very attractive circular pattern will be on the outside and I do plan on using Duratex. Aside from the aesthetic considerations do those of you with cabinetry expertise think this is a sound plan?
