Have you checked the cabinet with a sine wave generator to make sure you don't have a rubbing voice coil (which can be caused by tightening the speaker down on a warped baffle), or loose panel?

How high are you running the bass horn? Indoors or outside? Are you time aligning it to the speaker used on top? With the near 180 degree reversals I would think anything much over 125 HZ would probably sound "funny" if not like outright crap.

A little more description of the "awful" sound would be helpful.

For the same volume, a "C" shape horn, like the Cerwin Vega, SDL, Lab Sub, Tuba, etc., allows the bends to be only around 90 degrees, which makes for better transitions. Not much you can do about that now, sorry.

One thing that would possibly improve the sound, and allow you to re-use the cabinet would be to replace the slotted horn throat with a "V" entry baffle the speaker on the left side of the "V", the "V" being the throat end of the first portion of the horn.

That change would probably make the horn sound slightly better, but might not get it out of the "crap" range.
