  • Build Log, Definitions or Cherry Bombs

    Concept, Active/Passive Hybrid sorta PA style build. MiniDSP will be used between the woofer/sub and coaxial top end. Passive between mid and compression driver. Drivers (All Eminence) Definimax 4012ULF-8, Beta8CX, and N151M8. I will be using an Adcom GFA555 bridged to drive the 4012s so about 325w/ea and an old Kenwood M1 (?) to drive the tops. Woofers will get 2 cubes ported with an fb of about 36Hz. Beta8 sees .65 cubes sealed.

    Enclosures are 33"H, 18"D, 16.5W on the front, 12.5"w at the back. Material is all 3/4" 11ply birch. Pocket screws throughout. The top. bottom, and baffle will also get an additional 1/2" layer of mdf. Still debating on the finish. One option I am considering is Rustoleum Rock Solid garage floor 'Cherry Bomb" finish. It is pricey consider how much of it I will actually be using. And I am not sure yet how it will work on the ply. So I am still searching for possibilities. A few pics for now. Hope to have the enclosures in final glue up next week Click image for larger version

      Wish I could hear them!
      I'm a big fan of BB ply, although I usually cover it with paint or veneer.
      You might try a stain or semi-transparent "candy apple" look.

            Unfortunately, I have been down for a couple of days. Chest cold and pulled back muscles. Darn! Monday then the sides go on.

                Sanding, roundover, and primer/sealer next.

                  For someone ailing, you do a boat load of work.

                    I'm really interested to see what results you can get out of that Beta 8CX driver...

                      Thanks Kenny. Doing much better now. They are essentially complete save sanding, priming/sealer, and roundovers. Should be coming home on Mon next week. Then on to testing.
