Use the same midhorn, tweeter and crossover as the seven π cornerhorn but scale the bass bin larger, like the version for the JBL 2241, but tune it for 22Hz using a 4" long, 4" diameter port.
The link above describes the bass bin you should use, but remember to make the port longer, 4" diameter and 4" long.
