Hmm, works for me. Anyway, it's a side view drawing of this picture which I assume is BF's Tuba 30.

I'm looking for an efficient design (tapped/folded horn) that will get to 30HZ -/+ for pro audio use, and can be built on a budget..

Labhorn - complex & expensive
Jbells tapped horns (possibility) would ideally like to go lower though
BFM cabs, would like a flatter responce than what they offer
Scoops (Only suitable for certain genres)

Any suggestions much appreciated

The big cabinet would do it with a slight alteration. The bigger S1, the lower it plays. 800cm s1 / 2800cm s4 would do it, but as you go lower, you end up overall xmax limited at a lower voltage. (800cm s1 is safe xmax from 30hz on up at 250 watts/44volts.) In .5pi its also flat to 30hz.

Hi Jbell, what would be the 1w/1m average & Max spl be for that, and mutlple cabs?

Do you know of any other drivers that mite be better suited?

Thanks for the help.
