Another F1/Turbo Style BPH, which I've been playing with. I'm going the low power, efficient woofer route. Thinking about budget. It should make some noise in ya average venue.

4 should get down to mid 40's
Have a look if ya want.

markk... i think you're slightly misinterpreting the plan.. if i'm not misinterpreting you that is... the line with 550 written through it is just indicating the length of the brace that goes sort of vertically / diagonally from the center of the base, to the back panel... if you get me?

Double the center brace (550) and move each one off to the side a bit - would make it easier to load 'tall' drivers into the box.... back of the magnet would sit between the braces
What 18" are you thinking of using ?

I'd also love to know how the C18-650EL respond inside this horn.........( the best available off the shelf driver I could acquire)..

....that, if it fits in.......
