This has always seemed interesting. Bill Fitzmaurice has made a career of developing horn-loaded systems, which are tricky to design. https://billfitzmaurice.info/David.html https://billfitzmaurice.info/David.html There's a series of PA cab designs called fEarFul, that incorporate the newer 12" and 15" woofers from Eminence. You might have to dig around to locate the actual design data, but I do know that the designs were carefully tweaked and are stoopid loud. In my own case, I worked out what SPL I actually need for my listening tastes, and chose a suitable woofer by keeping an eye on the close-outs at Parts Express. The drawback is that my designs are irreproducible because the parts are sold out. But they're also not worth publishing. The benefit is that the prices are often pretty compelling. Lower specs also reduce the requirements for the tweeter and any other components such as crossover.
