[QUOTE="Max Warasila, post: 211450, member: 3845"] To add on to what Peter said about the trap version - it's not impossible. I looked into building them, and somewhere deep in my archives there's a 3D cad version of the box that has 15 degree angles on either side of the box for 30 degree splay between them. There are several considerations in building it, however: [LIST=1] [*]The difficulty in cutting the baffles is extremely high. It requires either extensive table saw jig work or a large radial arm saw to do by hand, and custom ground (or changable) chamfer bits to CNC route. While this is clearly possible, as these kinds of baffles are used extensively in designs by companies such as d&b, Meyer, L'acoustics, JBL, and others, on a small scale it is pretty much unjustifiable to have the entire cabinet be a complete pain in the butt to build. [*]The front of the cabinet becomes significantly larger to preserve a minimum internal width of 12" at the rear of the cabinet for where the 12" drivers fire into the horn. [I](If I recall correctly, it would have been nearly 600mm at the front, as compared to the current... 450? I don't remember.)[/I] [*]The horn geometry for the bent horn would likely have to be changed, resulting in extensive prototyping issues. [*][B]Ain't nobody got time for that.[/B] [/LIST] If these were being made en-masse as a commercial product, this would be more of a possibility. For a DIY project, though, this is just too hard.
