Default 150 HZ Tractrix contour

I have been tosing around the idea of a Tractrix contour for a midbass like the one in this website http://www.volvotreter.de/pics_plans.htm
has anyone out there tried this set up ? would it be possible to have it cover the entire volical range say 150 to 3500 HZ. then cross over to a small saliad bowl horn? what would be a clean driver for the 140 hz horn? or is the EV EVM 12L driver the best to use ?
please give your in put thankx

this is really a guitar speaker, gets very peaky above 1K
Fs is 55Hz, so is usable lower than 150Hz
