I'm kicking around the idea of building one of these since less than 100 were built, and the look and design seems way cool. It's an SVT 610 sized 4x12 with two drivers on the top, a wedge-shaped port/horn in the middle, and two more 12's on the bottom. I'm talking with a guy in the UK who owns two of them and is being gracious enough to give me dimensions. As I understand it, special Fane speakers were used in this cab. I'm attaching a side-view drawing of it. Is this a folded-horn or more like a conventional ported cab? Any recommendations on speakers? Initial thoughts?
