I used the MCM driver and pine plywood from lowes/home depot (I'll be going to a lumberyard next time...).
This is my second project ever building a speaker cabinet out of wood, I built a small 2 way bookshelf using drivers I had lying around as a warm up for this one. I'm very pleased with the build results, considering I made it in my 10x12ish dining room using tools that would make a carpenter cringe
The finish looks a lot more even in person than in the photos. I did a few coats of primer after sanding and using wood filler for the more offensive cracks/screwholes. Then I used some textured spray paint to cover up some of the woods imperfections...I really didn't realize how bad the plywood was until I tried to get an even coat of primer on it...
As for the sound, its well beyond what I thought I could be achieved with a sheet of plywood and a $30 8" driver.
The bass is very clean, and the output is shocking. I've ran it some at home, and at the office and its had quite a few dropped jaws. My building at work is about 60ft wide and probably about 150 ft long. I had people from the other side of the building (through at least 4 walls) asking me if I had heard the car out in the parking lot that was making their lights rattle....and that was maybe 30-40% on the volume knob. I'm powering it with one of the Foster WF-100k plate amps, TY very much to whoever it was that suggested that amp, your username escapes me at the moment. I'll try to post some detail/build photos throughout the day.
It sounds amazing, even in the minivan where it's getting fed a full range signal from one the four speakers from the stock stereo...
