All the parts are narrow and can be cut on a little bitty $99 table saw. Nearly all the parts are the same width. If you break the design down into 4 parts it really is easy.
1. the box
2. the driver baffle group
3. the inner labrynth
4. the exit mouth
You cut every part of the same width (including the front and back pieces very important)at the same time with the same saw fence setting. Then cross-cut the lengths.
Attach the front and back, top and bottom to one of the sides.
with the inside of teh side facing up measure, mark and draw the pattern of the sub-assemblies on it. Just position the sub-assemblies and trace them.
run a bead of urethane construction adhesive like PL 200 on the tracing and press the sub-assemblies into place. Wiggle them a bit to get a friction, or "rubbed joint" adhesion.
wait an hour
run a bead of glue on the exposed edges of the sub-assemblies
position the remaining side, wiggle a bit and weight it with 40 or 50 pounds of "stuff": books, sandbags, dead cats, whatever
wait overnight
install the driver (oh yeah, you should have installed the binding posts and run wires through the driver baffle labrynth before you glued the second side on)!
connect to a tube amp and a turntable and listen..........
