all of these velocities are at 140db.

why on earth do you want to do 140db in your shed? you won't listen that load for long, or, if you do, you won't hear anything for long.

Seriously, the velocities go up with SPL so of course you are seeing high velocities. Chances are you won't hear the air noise at those sound levels. Turn down the level and the air noise will go away.

If you could be satisfied with just 6 db less SPL, you could cut back from 4 woofers to 2 and save a bunch of money as well as reduce velocities

I'd just use the same dimensions that Danley uses:

Midrange taps are 3/4" in diam, 3.5" from throat

Woofer taps are 2.5" in diam, 10.5" from throat

Woofer ports are 2.5" in diam, 14.5" from throat

Works quite well, I just feel kinda bad ordering anything less than a hundred, since they're hand-assembling them.
You can order 16 pieces at one time at Misco. They are very friendly.

This is the original used in the unity horn project from Lambda.

Thanks PB. And if you look at 2.5" ports for the woofers that is quite high for velocity also.

This wont be for just my shed. I am planning on using these speakers for an outdoor cinema. When they are in the shed they will be used at much lower volumes. I am just planning on keeping velocities down at its max potential. Plan for maximum and use 75%. Thats the idea anyways.
