For those interested, here are the AR.com Kit Cabinet specs:

¾ inch MDF material

Outside dimensions are
13 inches high x 8 ¾ inches wide x 9 ¼ inches deep

Inside dimensions are
11 ½ inches high x 7 ¼ inches wide x 7 ¾ deep

Port size is 2 inches in diameter (ID) x 6 inches deep from rear surface.
Rear Port hole is centered (widthwise) and 3 inches from top to center of port.

Speaker input terminal hole is 1 15/16 inches in diameter. It is countersunk for the flange 1/8 inch deep x 3 inches in diameter. This can be changed if you desire another type or size speaker terminal. Rear Speaker terminal hole is centered (widthwise) and 3 inches from bottom to center of hole.

Front Tweeter hole is 3 5/16 in diameter. Front tweeter hole is also centered widthwise and also 3 inches from top of cabinet to center of hole. If you opt to countersink the tweeter, cut 1/8 inch deep x 4 1/8 inches in diameter.

Front woofer hole is 5 5/8 inches in diameter. If you opt to countersink, use 3/16 inches deep x 6 15/16 inches in diameter. This will now change with the new Seas driver.

Front woofer is centered 4 ¼ inches from bottom of cabinet to center of hole.

If you choose to increase the cabinet thickness to 1 inch, increase all the outer dimensions (WxHxD) by 1/2 inch and compensate for centering all holes!

Although the discontinued Peerless and the new Seas driver used in the kit allow for a larger cabinet, I designed the DIY specifically to produce a very tight, clean upper bass and lower midrange and felt most builders would use a separate subwoofer for the deeper bass frequencies. This also is the reason why the speaker is able to play extremely loud and clean without distortion, figuring a good high current amp is used.

Success!

Ed, Now you got me very tempted to build the cabinets myself... Thanks for the detailed info on the cabinets.
