Sorry, that one isn't available anymore. I may be able to dig up the plans on an older hard drive, but it isn't really necessary. If you want to build a seven π for use with a JBL 2241, 2242 or 2245, scale the bass bin cabinet up to being two feet wide and tune it to 30Hz. Scale all the dimensions that way, so it will be four feet tall, etc. The midhorn, tweeter and crossover are all the same. A more complete description can be found in the post called "seven Pi-18 cabinet dimensions."
