I've sent plans to your email address.
Kits include the binding post terminal, but crossovers by themselves do not. The one we ship in the kits need a 2-1/8" x 2-7/8" hole cutout.
The four π speaker and its crossover are specifically designed for the JBL 2226H. You'll want to buy our H290C waveguide, because the crossover was designed for that as well.
For a center channel, you can simply omit the port, if you wish. I would leave the left and right mains vented, as designed. Also use flanking subs to smooth room modes and the self-interference anomalies from floor bounce and the reflection off the wall behind the speakers.
