Thanks for the info. Im pretty excited about building these since this is about the only speaker design Ive not had any experience with. I tested the tweeters and they seem to sound reasonable down to about 4k. As far as clipping off the phase shields of 64 tweeters, I think I'll pass. Im going to do a fairly quick build just to get a feel for the sound and then look at a high performance design. I picked the tweeters simply because they were cheap, easy to mount, and have pre-soldered wires on the terminals.If the Pioneers do a good job then maybe I will invest in some Dayton Pt2s as others have.

BTW, I looked at the Selah Audio site and couldnt find any reference to the Linus2 kits. Are they still available there?
