[QUOTE="Boyd Williamson, post: 206790, member: 10607"] I had an idea for this box that I thought might be of interest... seeing as this is a symmetrical design, it occurred to me that both ends of the cab could have 'top-hat' speaker pole mounts, one of which could be a custom job with a say, 7 deg downward tilt, and be mounted further forward to maintain the C.o.G. I've encountered the down tilting capability on a few commercial speakers now, and in certain rooms & situations I quite like it. Having the flexibility to do so by flipping the box seems kind of neat to me. I considered if they could both be on the bottom of the cab, but figured it might obstruct the braces too much. Sadly it seems a 'spec' pair of these cabs might be a while off for me yet. So, in the spirit of D.I.Y. I'm considering having a crack at a test box with a pair of Eminence 3012HO's I have on hand, and a Radian 745NEOPB (which will 'supposedly' handle a 500Hz xover @ -24db/oct, or 900Hz @ -12db/oct) Hopefully this will work ok at ~700Hz -24db/oct in practice. Any idea on how well the 3012HO might work in the midbass horn section? It might seem like sacrilege, but at the moment I don't 'need' the ultimate in performance for what I'm doing, so any improvement over my current D.I.Y. cabs, and I'm winning :)~:-)~:smile: [/QUOTE]
