Also, I play mostly indoor small or medium venues, so that throw thing could be a problem.
...
I would also pick a single long horn design with the speaker on top, since I read here that longer horns are needed for low bass response, and having a speaker high up would make it easier to hear.
There is a time and place for bass horns, and the above is not it.
I've been doing the bass horn thing since the 60's, have designed and built a good number of them and know how they work.
A bass horn is
not the right cab for the venues you play.
My bass horns are used for:
- Outdoor Gigs
- Slamming DJ Gigs
Bass horns are herd animals.
Unless you are constructing a built-in, the horn must be sized small enough to transport.
A transportable horn does not have sufficient mouth area to full produce low frequencies.
This means multiple bass horns summing to a larger mouth area.
I haul mine in a 5x10 trailer.
The horn discussed above will
not produce any deep bass because the path is too short.
The horn path must be a quarter-wave length, or longer, at the lowest desired frequency.
Below this frequency, it is just a direct radiator shouting into a tunnel.
The modern equivalent (and much better design) of a short path horn is the
BFM Jack Series
'Throw' is a misnomer when applied to bass.
Camp fires do not get hotter 20 feet away, and neither do bass horns get louder at 20 feet away.
Speaker cabs are pressure devices, and the highest pressure is always at the source.
All moving transducers generate motion distortion which introduces higher frequency components into the produced signal.
A folded bass horn attenuates higher frequencies within the folds of the horn where the wave length exceeds 1/12 the radius of the bend.
Long wave bass travels much farther than short wave highs.
Blue whales sing between 10 ~ 40 Hz because their sound travels so far.
What you hear far away is the bass left over after the highs are attenuated inside the horn, and after the highs have faded over distance.
Commercial direct radiator cabs produce little true LF energy, and do sound quite thin when heard at a distance.
My bass horns bring the Noise Police who get complaints from over a mile away.
OP, this is a long explanation of facts and expectations. It has nothing to do with G.A.S. or just wanting to tinker with the old W-horn designs.
In your situation, I would build a tall 'n skinny 2-way direct radiator.
Put the woofer on the bottom for floor coupling, and lower center of gravity.
Put the highs on top closer to your ear.
A 39" or taller box is easier to wheel about than a clunky 4x10 or other squat configuration.
so it's OK but it's the one with the, old alnico magnet drivers in.
