Well, I'd really like to get a Schroeder 1012, but at close to $800, I was thinking about building one. The external size is 23"W x 16"H x 16"D, so I'm pretty good to go on the general size. Actually, a half sheet of quality plywood would be sufficient. The issues I'm having are the specifics on the internal bracing, and the angle or top-down triangle formed by the side fired speaker. Also, I can only assume there is a port, but I don't see one on any of the picutres. If anyone out there has ever opened a schoeder, or at least can measure the side fired speaker specs, I'd appreciate it.
