Speakers designed without a sweet spot?

All is true so far, however if you use Distributed Mode Panel (DML), the driver excites panel resonance as opposed to ordinary pistonic motion, DML panels have a wide dispersion pattern and wider sweetspot, they are are dipoles but in almost all commercial implementations the backwave energy is damped, so that energy above 250Hz does not overpower the traditional woofer driver.

Von Schweikert use a unique home-made crossover for this very reason,speakers with na narrow sweet spot are a waste of time in my opnion hence why i use their VR-1s

Do we have actual measurements to verify the wide dispersion of NXT speakers?

I do not have the dispersion pattern measurements for my specific implementation, but this AES paper gives peer-verified measurements for a typical DML panel alias NXT speaker implementation.

Some measurements for the Cyrus Icon
