Wayne,

I have finished building a pair of 7pi and am delighted with the results. They replaced a pair of Sound Dynamics 300TI in a room which is 15' wide. They sound great and eliminated the effect which always reminded me from where the sound was originating. The 7pi just creates a large soundstage, bigger than the room where they are located.
Thank you very much for sharing your design.

I designed my own crossover PCB just as part of the enjoyment of building my own speaker system.

Also built a case for it.

Here is the crossover encased

To fit behind the mid-horn I added a base to keep it vertical

This is how the crossover sits on the bass unit
