I'm working on a monkey coffin with the following drivers: Transducer Lab Ceramic tweeters, Satori MR16PNW midrange, and DIYSG Magnum 12 woofers. The goal is 90-91db efficiency with an F3 between 40 and 45. I will be doing roundovers on the edges and a separate housing for the mid and tweeter sections. Cabinets will be mirrored. I even considered doing different designs on each one--sort of a Soviet versus US space propaganda.
(1) Before I start drawing up blueprints, I would like feedback on the very rough mock up below. The design idea is a tribute to the stereo era, as well as to the golden age of space exploration. Admittedly, there are preferable [acoustic] ways to design a cabinet today, but I'm trying to do the best within the confines of this general aesthetic.
(2) How recommended is a waveguide on that tweeter on such a wide baffle? It should naturally cross around 2k to the Satori, but I'm wondering about diffraction on such a large baffle, or anything else tweeter-wise I should be considering.
(3) Any other thoughts or foreseen design challenges before I get into it are most welcome!
