Or if you want to keep considering horns, you should be able to use the B&C 21SW152 in a GJALLARHORN or LOWARHORN and get output that's pretty impressive.
I will have to check out the Ghorns. and the lowahorns. The thing that attracted me to the othorns are their size. I am pretty sure those have a larger footprint. I am planning on using the sealed 18's nearfield to give that low rumble so I don't think I will need 8. For that I might even be fine with um18's. I'm in a huge room on a concrete slab so I'm not going to be able to fill this room with sub 20hz no matter how hard I try.
I know what you are saying though that the sealed won't be able to keep up with the 21 horns. I may just go with cheaper sealed and just keep adding them until l' m tired of building them or run out of space who knows. I just know for sure I want those 21's
