I figured I'd start a new thread because some of the others are starting to get a little "long in the tooth"
Since the mid and high drivers are in flux I'm starting on the bass units and then will add the "head" unit in the future.
I've modeled a vented cabinet for the two Aura 12's in UniBox. The cabinet size is 145 liters (5 cubic feet) with a 10.15 cm (4 inch) port that is 43.7 cm (17.2 inches) long.
Outside dimensions are roughly 44 inches tall, 17 inches wide, and 27 inches deep. These dimensions allow one to get four side panels of the actual cabinet for glue up out of a standard 4 x 8 foot sheet of MDF or plywood. I've been doing layout of the side panels on a 2 x 4 foot sheet of MFD so that I could be sure my calculations were correct. The front baffle will be 6 inches thick and faceted in "Avalon" style. The whole cabinet is slanted back at a 10 degree angle and is internally braced with four shelf braces horizontally as well as vertical braces between each shelf. All braces are one inch thick and all walls are two inches thick. I will try to be more detailed in construction description and pictures as I progress.
I'm sorry I'm not a CAD person - I normally go from a sketch to a full sized detailed diagram when I work because I like to have a full size representation to check my progress. I will post a picture of the cabinet/brace layout (excluding the front baffle) later today or tomorrow.
I've already purchased a stash of Santos Rosewood veneer for this project so these will match my prior "Avalon" effort!!
I should have the cabinets finished and ready for testing in two weeks.......... just kidding!! I'm hoping that I'll have something ready for listening by the end of August. I'll most likely start glue-up this weekend.
