Very cool! I have a set of SP12B with the whizzer cone, awaiting attention. I pulled them from some raggity DIY boxes that were loaded with assorted crossover parts and unknown brand oval plastic horns. I'm not too familiar with that tweeter - where did you find them? I'd like to try something like your setup at some point.

You may start this week-end end project that i did 2-3 years ago.
Very easy to implement and it sounds great! Enjoy
Cool! What is that project comprised of?
It is a EV SP12B with a Peerless textile dome tweeter crossover at 2,5Khz.
Simple plywood 3/4'' thick and cut at 24'' x 48'' with a base holding the OB's plywood panels slightly at an angle 5 to 7 degres that's all.
EV SP12B is low-pass filter at 6dB/oct. around 2KHz.
Peerless tweeter high pass at 6dB/oct. 3KHz, i did spread the responses as both units comes close in gain near 2,5KHz.
Sounded great because i had 2 pairs of EV SP12B's, the buyer came for raw drivers only, but he heard this , he took them.
The EV SP15 project is more complex and difficult to voice, but once properly dialed, it sounds better than the EV SP12B's OB project, better bass, and more midrange defition and precision of tones.
Here's a pic of theEV SP12B's OB back quite simple week-end project.
Enjoy!
Really Cool! Thanks for the pix and info!
Hi, the tweeters are sold by:

They are mostly used in car audio, but frankly they are great performers.
Theses are aluminium domes, they also have textile domes too.
