My design has a 7.5' x 23 inch x 8 inch array, with a vertical band of about 23 inches of tweeter, and the full 7.5 feet of 3 inch Sammi Midranges. I also have a smaller separate woofer array about 32 inches high consisting of 5 Audax 6.69 inch AP170MO's(they may be cut off at 80, or let to roll off naturally in their sealed enclosures---more likely).
This array is doubled of course, a set of two on each side. Should the tweeters go on the outside of the large array? And should the woofer array go outside of the large array, or inside of the large array.
The double 12 inch subwoofer that takes over at 80hz in a ported isobaric enclosure, goes anywhere its IKEA endtable look fits in the room and in the measured acoustics(RTA with Apex 220 microphone).
