I just finished the baffles on my PE 69 cent mid and PT2 array. I went ahead and bought 16 of the PT2's - figured I'd take your advice:-) It's open baffle but it'll be so close to a wall, I don't expect much dipole effect.

Here's a pic:

I know the baffle looks a little odd but the array will be sitting right next to some very large bass boxes and the effective baffle will be another two feet to the side of the mids. Don't know how the extreme width of baffle will affect it but it won't hurt in getting the most outta the lows. I'll start wiring tomorrow and hopefully get to fire them up before the day's out. Thanks for all your help.
