Thanks for the information and the plans. The "J" models are used and from a thread on AVS. The guy bought 21 JBL 4648 cabinets, and lots of other JBL stuff. Seems someone was upgrading a multiplex theater. I thought it might be a way to save a few bucks on a 4 pi build. Actually he posted a pic of one and it was a J but hasn't confirmed that they all are. I have to see how this pans out and may still go for it if he has any 2226H's. Again, thanks.
