A7 vs 9845A

[ClassicComics]

farthest seating away from the speakers is about 20' - closest - where people will actually be sitting is about 14'

That's too close for the A7 to 'gell' to a point source even behind a screen, though horn on top is better close range than positioned in the port, but baffle mounted woofers would definitely be better.

If you don't want to give up any of the A7's mid's 'punch' and/or usable efficiency, then use dual 15" as I do except mounted side by side since it better blends to the 511 when using a 500 Hz XO as well as controlling directivity to 'in the ballpark' of the A7. Obviously, you'll have to DIY or have someone build the cabs.
