    Dimensions for Speakeasy Roadbox Convertable

    I would like to build a Speakeasy Roadbox Convertible replica and would like to know if someone has or could direct me to the cabinet dimensions for both upper and lower cabinets.
    Any help would be greatly appreciated.

    Since Speakeasy is defunct unless someone who has one can measure for you, you may get by with ballparking the measurements based on the rotor/speaker sizes you plan to use and work from there. Don't think there needs to be an exact dimension used as those parts are probably what Steve used to design the cab.

    If I were building this, I would use thinner ply to reduce the weight and allow the cabinet to resonate. You could get by with 3/4" for the floor, back panels, woofer and upper driver shelves and then use 1/2" for the walls and top. Or 18mm and 12mm ply.

      wow. Is that 3/4 or 4/4 ply? That picture makes it look thick!

    Having built several of these devices (not the Speakeasy, just generically), I can tell you this sentence is exactly true.

    There is nothing redeeming about the ubiquitous "3/4 plywood" that many companies tout. It's sometimes handy for hard road use for things that get stacked or tumbled around. But generally, 1/2" is structurally fine. And consider this: even if it takes a tragically catastrophic gouge that penetrates the wood, so what? You got slots in it ANYWAY.

    Resonance? I dunno. Sure. Stands to reason you'd pick up better resonance in a thinner cabinet, but as the whole purpose of a Leslie is sound modification, that might not be a top priority consideration. But it can't hurt.

    Anyway, I've made mine from both light and heavy materials and will never make another thick one. The sound is in the bakelite horn, almost entirely. The rest is whatever a guy wants do. It's a long way from rocket science.

        Sounds good.

        Problem that's always been with organ gear across continents is availability, dealer/parts representation, shipping and taxes.

        Amp is separate from the cabinet. More pieces to fiddle with, move and connect. Non-classic Leslie connectivity.

        EU market, why not.

        Conus? Don rules!
