If there's one thing I'm really good at, it's waffling on the implementation of audio gear.
I'm meeting with a local cabinetmaker the first week of October, in hopes of coming to an agreement on building a pair of unfinished plywood cabinets.
Next up is where I wish I had some graphic design skills:
My plans right now are for towers that are 47" tall x 23" x wide x 16" deep. Cabinets would be slightly narrower than the Altec 620, with Duplexes mounted slightly closer to the top of the baffle - the hope being that the baffle width and driver placement aren't fudged to the point that the Markwart crossover wouldn't work well, if implemented.
Cabinet dimensions are somewhat beholden to the available sizing of 4' x 8' 3/4" marine-grade plywood sheets and 2' x 8' veneer rolls. Also, the height helps get the tweeter at ear level.
Drivers would be surface-mounted, and the front baffle recessed ~1". The grills would be also be made out of cloth-wrapped 3/4" ply, and would have cutouts for the drivers - almost like recess-mounting the drivers.
I want to commission two sets of front baffles, and two sets of horizontal upper bracing, so that I can configure the cabinets either with the 604 and Fostex FW-405 15" woofer on the baffle, with a solid interior divider, or just the 604 on the baffle, with a window brace instead of divider. Preliminary configuration would divide internal volume between a ~3.5 cu. ft. chamber for the 604-8G and a larger ~5.25 cu. ft. ported chamber for the Fostex FW-405. In this configuration, the helper woofer is always run via DSP crossover and separate amp, regardless of what I'm doing with the 604. In the alternate configuration, the 604 is by itself in the ~8.8 cu. ft. ported enclosure.
First off, is that description clear? Second, does it seem like a good idea, over building a plain-Jane 620 or MLTL?
