Yes, think: Klipsch Belle.
They sound fantastic with a simple crossover.

This kind of reminds me of a folded version of the "bass" horn used in the late Le'Cleach's inspired (or designed?) Le Grande Castine. Granted they didn't flip one of the drivers and they aren't perfectly parallel, but still slightly reminiscent.http://www.6moons.com/industryfeatures/grandecastine/1.html
Hmmm....the more I think of it, I don't think they are very similar at all. The LGC's woofers are OB with a horn on one side, whereas your is sealed(?) PPSL with a horn expansion. I'd like to model this some.

They did have it that way they they changed it."We also had poor integration between lower and upper horn caused by the proximity of side and front walls with our open-rear bass horn. That never was the case in larger rooms. Now we are working on experiments to partially or totally enclose the 2 x 15" woofers without losing the openness of the sound—one of the strengths of this design—and facilitate integration with smaller rooms............. At this juncture, silence set it and a few months passed. The men were busy with their redesign............ After many trials, we found that the best way to limit these room interactions was to have a slightly deeper bass horn with a single driver instead of the two earlier sidefiring woofers."

That is cool. Did you model what effect the folded short horn section has? I imagine you can do this in hornresp or akabak. Does the result have more bass than the original lascala, or about the same rolloff?I see now the rightmost picture in middle row shows the rear expansion, I didn't comprehend what I was looking at at first.
