Don't modify the four π speaker, but you may want to high-pass the signal going to it. For subs, I'd suggest a JBL 2245 in a 10.0ft3 box tuned to 30Hz or a LAB12 in a 3.5ft3 box tuned to 22Hz. I can send plans if you like. I realize you said you didn't have time to build, but you could probably find a good cabinetmaker in your area to build speakers for you.
