    I'd like to build a pair of 112 cabs in my shop since I have all the equipment and materials handy, as well as hopefully a pair of nice 12" speakers. I don't know anything about cabinet design yet, but I can draw, cut and assemble whatever I need to very close tolerances. I'm thinking I may be able to get away with no horn on these since I usually shut off the horn on my Avatar 115 anyway, and I think these 12's have a higher frequency response. If I need to add in a tweeter that's cool too and I would be up for doing some research into crossovers if I end up needing a tweeter after all.
    So how do I determine cabinet volume, shape, port configuration etc? The speakers are Genz Benz GBE 1241B's

    Check out Genz-Benz's website for more information.

    They don't use the 1241B's anymore in any of their enclosures. However, their LS112T has a single 1241C in it. It sounds like the C is the newer, "better," model. As it's a rare and uncommon speaker, you won't find much on it on the internet. I think your best bet it to mimic one of the Genz-Benz LS112T, and you'll get close to what's best for the speaker.

    I would recommend e-mailing Genz-Benz, or waiting for Roger (aka hasbeen) to reply. He's the Product Manager (correct me if I'm wrong Roger) of Genz-Benz and has always been helpful with me.
     
  3. Check out this page it will give you a some ideas of what is involved. I am building my cab tomorrow best of luck. Hopefully the speaker arrives :)

    Also be sure to download programs such as winSID, they can be quiet handy in determining speaker responce, and cab size as well as tuning.

    I will try to take a few pictures for you during construction of my own cab also- Internals and stuff like that :) Which you may or may not find helpful.
