it's an educated guess, but surely this would only be an improvement ? 

and it's only 75mm added to the original when cut in half.

now therin lies the rub, and is part of a subject i hope to raise in this section before too long. bifurcated horns... to what extent do dual driver horns "share" the horn path, would the single driver variant infact be significantly more than half of the dual version? fiddling in hornresp isn't getting me too far as i don't know if, once you have set it to dual drivers, if the doubling of vtc, atc, vrc etc will accurately represent the dual chambers and throats of something like a martin 215.

i have a sneaking suspicion that the single driver versions may disapoint slightly, multiple driver horns do seem to exhibit some rather cool properties.

1000mm - 50mm for the ply = 950�divide by 2�= 475

475�+ 75�= 550�+ 50 =�600 

bigger mouth, bigger driver chamber

could even do it 580 total.

and still stack them on there sides as the original, or upright�(bottom to�bottom) like the t18.

seems as good a way as any of going about it, on a purely guesswork front. thing is you could actually model it reasonably accurately for single drivers in hornresp (one would have thought, see discussions of neverwinter's 18" punisher and ceharden's 15 hornsub over in new projects forum for interpretation of vtc, atc and horn length for Vee wedge style throats). i'd definitely do that before comitting to building as they are clearly designed to be used in big piles and you'd never know if your mod had worked until it was too late!

edit. james! not even the 60ft wall of martin F2 sounded as good as the Selenium rig, and remember i dont do drugs so i wasnt influenced in anyway.

better than that brute? freeow! now i am seriously impressed... drugs make music sound cool by the way, perhaps you might concede a quick baloon of nitrous oxide? it's over awfully quick and gives a fantastic plate reverb...
