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.

Hi epa, what driver is that for? cheers

i moddeld it wit a bms 18 850 v2.
but there are more drivers that wil do good in this model

defimax 4018 lf
b&c 18nw 100
beyma 18SW1600Nd

but i like the bms best for the huge x-max lin.13mm math.16 mm

with 3 you can play sine waves @ 138 db whitout exceeding x-max , offcourse music louder
