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.

I thought the Pi midhorn was made to use the 10" Alfa driver. Wouldn't a 5" driver be too small for the horn throat? Cheers.

"I thought the Pi midhorn was made to use the 10" Alfa driver. Wouldn't a 5" driver be too small for the horn throat?"

I am not sure if the Pi mid-horn is specific to the Alpha 10".
I belive that Wayne has used a JBL 10" driver with this horn as well.
Possibly he will chime in here and fill us in on other driver options?

About the 5" Faital driver, the guy who posted using it in the tractrix horn used it with a throat area that was round and close to the diameter of the driver. I honestly don't have a clue about the physical requirements to use such a driver. I just thought I would throw it out there as a possible alternative.
For what it is worth, the guy who used the 5" Faital driver replaced an 8" B&C, claiming that it was as dynamic and could keep up with his system.

Good luck with your project, and have fun.

My favorite combination is a JBL woofer in the bass bin, Eminence driver in the midhorn and B&C driver on the tweeter horn.

The crossover for the B&C DE250 works perfectly with the TAD 2001. Their impedance, voltage sensitivity and response are very similar. The TAD has a smidge greater extension.
