I ran your combo looks like a good power taper for impedance but for the sound, don't know. Your impedance is going to be at 8 ohms with that wiring. The only difference is I'd wire them a little different.Parallel groups - 6/4/4/3
Series connections - 1,2,3,4,5,6/7,8,9,10/11,12,13,14/15,16,17
Speaker 1 at base - 17 at top
I'd try this for starters, like on my line arrays this is about the way there wired, you just have to build and test, listen, make changes test again, etc.etc. until you get the tapering the way you want it.
