Your Imperial's look great, very clean. Is that a JBL waveguide setting on top the Imperial cabinets? Would you give me your impression of this horn with your compression driver that you are using? Also, would you include any impressions that you may have using the JBL waveguide with other compression drivers, if you have used it with others that is?

I am curious of which cone woofer that you will be using with the Pi mid-horn?
I have seen a post regarding this little 5" Faital midrange on another forum, the Faital Pro M5N12-80. The guy used it with a tractrix horn with an open backed chamber. It may work well up high above 400Hz or so, don't know. But, it has me curious as well.

I was thinking maybe it could take the place of a 2" compression mid from about 700Hz or so, and up to around the 2k to 4k range, where another 1" compression driver / horn would take over.
Just thinking out loud.

But, this little 5" midrange may not have the radiatiing area to keep up with your 15" Jensen, again, thinking out loud.

Keep us posted of your progress with the Pi mid-horn and tweeter?
It sounds like it could make for a very interesting speaker.
