JR- Is the prediction with 1 box on the ground, or 2 or more?
Also, are you looking at 1 or 2 HL-10s per box? Sensitivity is one thing, but you also need to look at where you run out of excursion.
Not a bad concept though, and could be somewhat similar to what John Sheerin was talking about.

2 HL10's per box. 1 box 1/2 space
40hz = 8 mm @ 600Watts
40hz = 13 mm @ 1200Watts
35hz = 12 mm @ 600Watts (Xmax = 11.1mm)
35hz = 17 mm @ 1200Watts (Xmech = 36mm)
30hz = 15 mm @ 600watts (Xmax = 11.1mm)
30hz = 24 mm @ 1200watts (Xmech = 36mm)
At 40hz and 1000watts it should be within linear operation. If used in multiples, I imagine it would be linear down to 35hz, but I am not sure how to calculate that.
The only issue I see is that they would really have to use them in multiples of 4 or more to to get noticable extension below 40hz.(just like the labsub) Oh and where to put the handles...there will not be much room on any sides that won't have a brace or a part of the horn under it...lol.
Edit - At 600 watts (RMS) it predicts 136 db +/- 2db 40-200hz put 4 together and that could be "stupid loud" out of a 48"x48"x36" stack of speakers, but who knows. It is always a compromise, but finding what is the best compromize - physical size vs. response vs. efficiency.
