Got them all together, and I'm pleased with the sound considering they cost about $100 to build. I also did some measurements, which are critical in designing a crossover. When you're talking "line array" you can forget about using a crossover design program, because woofers behave very differently when they are arranged in an array versus a point source.
Here's the in-room frequency response of one woofer measured at one meter. It's the one directly below the tweeter. No other drivers are connected. Notice the peak between 5 and 6khz. Any crossover you designed for this woofer would have to attenuate that peak.
