I'm not an expert by any means, but I have done a lot of reading research, I know the basics, and hopefully I'm not wildly off base here. Experts, please chime in and tell me how wrong I am. Goals - Small size: I'm going on tour and the smaller I can make my gear loadout, the better. - Lightweight. This should come with the small size and neo drivers. - Widest dispersion of mid and hi range frequencies as possible. This cab will essentially only serve as a bass monitor for the drummer and I. I will be going through a sufficient PA at all venues on tour. I use a VERY mid heavy tone. - Minimize problems like comb filtering and beaming. Things that are not goals - ALL THE BASS MUD - ALL THE SPL So. Here's what I'm thinking. (Please note, I haven't drawn anything to scale yet.) The cab will be a prism, with this shape as the base. It will be 36 inches tall, bringing the internal volume to 3752.6 in cubed. It will be loaded with twelve of THESE in a 2x6 line array. Modeling those drivers in WinISD with that volume gives me this: Which looks like bass response I can live with. I use a HPF set somewhere around 50Hz. They'll be crossfiring, 50 degrees off-axis. Assuming a 1/8in protrusion (I don't have the drivers in hand yet), if I've calculated everything correctly, I can mount them .06in away from the corner. This number seems ridiculously small but if I've made an error, I can't find it. Now, I'm not entirely sure which point on the speaker I need to calculate point source spacing from when the drivers are not on the same plane. I used the plane of the baffle at the center of the driver for these calculations, leaving me with a horizontal spacing of 4.66in. There will be 3 inches at the bottom for ports. I've been unable to find really helpful information for figuring out how to do them. WinISD tells me I could do four 2in diameter ports .69in long for that tuning. Those would end up being cross fired as well, of course. ANY advice on this particular subject would be much appreciate. The cab will be wired to 5.33 ohm and will be able to handle 300W RMS, which is just about what my amp is going to throw at it. So again, please, tell me all the ways this is a terrible idea. I'm too worried that I'm actually totally clueless to drop the money on the drivers.
