Need driver suggestions for PA Cabinets

[joeyknapp]

I am going to be building cabinets for PA speakers for our church. The cabinets will be used when we have concerts. We open the church up to local bands to come and play, and Im in the process of building up a better PA system.

The area is 30ft x 65ft with a 9ft ceiling.

I plan on using a 120x40 mouth and need suggestions for a HF driver
I also plan on the cabinet having either 1 or 2 15" or 12" drivers. I am thinking of having the two woofers on about a 135 deg angle, with one woofer perpendicular to the side walls, and the other woofer angled in toward the center of the room. My hope would be there would be a little better coverage near the front of the stage for the kids that are at the very front.

So, to recap
HF suggestions and Mid/woofer suggestions are appreciated.

Oh, I would plan to have about 300 to 600 watts per side on these cabinets.

I will also have some subwoofer cabinets that I will build (suggestions for subs appreciated too!)

thanks,
JOey

You are using subs so my advice is definitely don't use 15's, but 12's or 10's. And don't build 2, build 4 trapezoid cabinets with 60 deg horns so they can be splayed to cover a wider area.
Kappa Pro 10 or Delta Pro 12 with the Selenium DH200E or D210 comp driver. B&C 12PE32 is another good option. Also look no further than the PV Lowriders for subs, unless you want horn loaded cabs.

That leads to comb filtering and does nothing to control vertical dispersion. A line array will control vertical dispersion and doesn't comb filter, look at the TLAH pro at <A HREF="http://www.billfitzmaurice.com">www.billfitzmaurice.com</A>.

Beg to differ... A line array is nothing but comb filtering in the nearfield. Doing one right is not a trivial undertaking and can easily lead to much worse results than a few trapezoid boxes appropraitely splayed to minimize overlap.
