I'm planning on building a 1 18 4 10 cabinet, but i've never built any cabinet before. I've done my research but from a carpentry angle it seems to simple to me. I'm not worried about the wiring (paying for that) but the plain construction. The exact plans i'm going to follow are as such. I'm going to make it out of plywood. The face will be as tall as the 2 10s and as wide as 2 10s and the 18. For the actuall construction i plan on making a box out of plywood, with wood strips on each inside edge, and glue on each edge of the wood strips so there will be no leaks. I bought some spray (can't remember the name offhand) to seal the speakers and keep the wood from vibrating, once i install the speakers i plan on filling it with insulation. Will this work? If not, why not and what do I need to do to fix it? Any tips apreciated thank you very much.
