Sensitivity,power output, and associated dimensions

Hi AKP holders,

I'm interested in this tech, and have done a little research, but having trouble finding any real world specs on these speakers. I did find a 6 to 35000Hz freq response mentioned on an audio forum in 2010. Maybe this has been done many times before, but does anyone know:

1. Sensitivity of these speakers in SPL@ 1Watt at 1 metre in dB or any similar sensitivity measure.
2. Useful max power output specs for a given area of pixels
3. Minimum number or area of pixels to achieve down to 20Hz

Thanks in advance
