The four π uses a larger midwoofer than the three π and has a much larger box. Both bass systems have relatively high Q drivers in a slightly overdamped alignment and both use the same tweeter. They're similar in many respects, but the three π needs a little more power than the four π, both because of sensitivity and electrical damping.
