Don't really know why it turned out to be a rear loaded design. A part of me loves the what scoops do to some kinds of music and I just wanted to see how far you could take it.
 
Here's the plot for one horn, which is 4 scoops or 8 sections.
 
 
The average sensitivity is 109.5dB and the f3 is 25Hz. Because of the steep rolloff its's flat from 27Hz. Overall response is 25Hz to 121Hz +/- 3dB.
 
I'm getting 4.7dB gain with 4 horns over a single horn, which is good. 6dB is the theoretical gain when jumping from 1 to 4 cabinets, but as djk rightly points out, cabs made from wood will never exhibit a true 6dB gain. 4.7dB is around as good as it gets and it's a sign that the constrution and bracing are working well.
 
In band max continuous output is 145dB with peaks of 151dB at 1 meter. Output readings measured with 6000 watts input, which is 1500 watts to each driver.

"Look" American, are you serious?  What do them looking American have to do with me calling you a douche bag?  +5 for attacking a countries people with ignorant views, and not the actual person who insulted you.

You had to source Cracked for something....

"You had to source Cracked for something...."
 
Hey, you been somkin that acid again mate.
 
Anyway,
 
Back to the world where we can all put coherent sentences together............
 
Just took a reading from the center on the Rubic horn. Test mic distance was 1 meter.
Weighting is linear (4Hz to 50KHz) and response was peak, 50ms rise time constant. Playing some Irration style tunes with some Infinite amps driving the stack.
 
 
Its ok standing within 3 meters untill a frequency above 60Hz comes in, then it hurts. It feels like when you accidentally hit your head on something really hard and it kind of phases you out for about 3 seconds. But its like that happening all the time so you just have to move away, or should I say stagger away as its like being in a fight with Tyson when those upper bass notes start playing. Other than being attacked above 60Hz, below 60 is very comfortable. Tracks with 25 to 30Hz just move you back and fourth in time with the oscillations.
 
Quick sketches of the inside can only happen in another life. Ha ha.

Are these really practical, at all.  Considering the 1850 isn't far from one of them, according to the specs on the plans.
 
You're right, there's not really much point in the Rubic horn when you can get a sensitivity of 109dB at 25Hz from 4 x 1850 horns.
