The Professional Series three π uses a first-order crossover. So does the Studio Series one π, two π and two π tower speakers now that the tweeter is a DX25 instead of a KSN1038. So your 2π → 3π upgrade idea would be very easy to do. Make the woofer hole bigger, pull the coil, swap the driver and one capacitor and you're through.
