I would like to use these motors in my new project for a center and rear channels to match my Selenium 7 Pi's. Any thoughs on which cabinet design to choose. I am a little constrained on size for the center channel as I have a screen hung above my fireplace for my projector. I have about 13" from the top of my screen to the ceiling. I can place it in front of the fireplace on the floor though. It would be centered between 2 2226h's in cabinets to get the lowest possible Hz.

I also would like to know if anyone is using false corners with the 7 Pi's. The way the room is laid out no longer give me 3 Ft. on either side of my horns.

That speaker looks really good in bass-reflex cabinets from 0.4ft3 to 1.6ft3 tuned to 40Hz. PiAlign suggests 0.5ft3 tuned to 38Hz with a 1" long port, 0.75" diameter or 0.5" x 0.875" rectangular.

Looks like it will make a great little speaker.
