Hi Wayne.
I wanted to thank you once again for all the effort on developing of pi speakers!
Here are some results of measurements that I took recently.
Microphone is WM61A and I used integrated sound card on my laptop.

The measured response looks excellent and similar to the measurements that I've done with the 3Pi (AE TD12S, B&C DE250 and Eminence H290). Try doing some in-room analysis and experiment with the speaker and listening positions. Even small changes can make for significant improvement.

Thanks
BTW, measuring was performed from 1m on axis with loudspeaker`s mid-center, with mid-center between drivers approximately on 1/2 room`s height.
Measuring equipment is as much poor man`s as possible
Mic stand and holder are the things that I am most proud of.
I will try to play more with room position and measure response.
I think my next step will be building flanking sub`s. What do you think of using some car audio subwoofers for this purpose?

Here are results of offset measurement.
on 15deg, which is normally listening position, response almost looks unreal.
Overal sensitivity of loudspeaker is around 91db.
Is there a thread regarding subwoofer drivers selections and how to connect and integrate them into system?
