Member mikebake has a pair of member 4313B's custom-built Sub1500 subs set up with specific attention to time alignment spacing, cabinet volume, and other transitional/crossover considerations that according to Mike are pretty darn compelling. I've no doubt that one could take the basic design philosophy of the PS1400 and improve on it with a custom design. I contributed some minor cabinet dimensions and spacing to help in the build process. Even the designer says a little more enclosure volume could be a good thing for the stock LE14H-3 driver.
The question then becomes, "Can one improve upon it with stock, consumer designs," i.e., a 1500 Array in place of a PS1400? I think the answer is "maybe," and also that it's possible to mess up a good thing rather than improve it.
When I get a little more time and as the discussion continues, I'll add some comments about the plusses and minuses of such an endeavor.
