Wayne, I have Theater 4's with Eminence Delta 15 woofers. Can these be used in the 7-Pi? What midrange drivers should I use?

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.

Can you please send me the 7-Pi plans I need for this enclosure, including the midhorn plans?

Thanks!

It seems that the bass bin for the Delta 15 is larger than the cabinet with other drivers. What are the differences in dimensions? Which drivers can be used in the smaller bass cabinet? (I probably cannot afford JBL drivers at this time.)

Also, what is the height and width of the midhorn?

I could not find the dimensions on your website.

The seven π loudspeaker is designed to use the Eminence Omega 15 or JBL 2226. It can also use the JBL 2225 or 2205 woofers. The midhorn mouth is 24" x 12". You'll see that and all the answers to all your other questions in the plans.
