And the dimensions are

2. 2 x 12 speaker cabinets. O.D. 27" wide x 20 1/2 high x 12 deep. 1/2 re enforced BB baffell, 1/2 BB re enfored back.

I dont think it will matter if the speakers are 16 or 8 ohm but I do tend to get confused about these things.

I want to decide soon about the speakers so I can make the cut outs and glue up the boxes.

Will take some pics and post somewhere for show and tell:)
