Work being done on the XPLS Series One with the revolutionary new PAD (Parallel Aligned Driver) cabinet design eliminates the problem of blending an electrostatic panel with a dynamic bass midrange driver and will combines the output from both drivers to emanate a seamless sound field.  The small footprint of the XPLS Series One is only 10 inches wide by 52 inches tall and 13 inches deep make it a great choose for audio and home theater listening. Easy setup along with it is hard to tip over cabinet. Also the bass cabinet non-parallel walls help control internal standing waves and reflection. 

Coming soon the all-new XPLS Series Two PAD (Parallel Aligned Drivers) cabinet design.

Measurement

I dislike measuring curved panel speaker. Why? Because the assumption is when you measure, a speaker on axes with a anechoic-gated measurement is you are receiving only the first signal arrival from the speaker to the microphone and only that. However, with a wide curved panel you are picking up some of the curved panel delay making the upper response look very rough. As a result, the interaction between the microphone and the speaker is much more complex then with most other speakers. In addition, the measured performance of the curved panel speaker is puzzling. Compared to a flat panel or a dynamic type speaker, the measurement can look worse, yet other and myself love their smooth midrange and beautiful high end along with the wide dispersion of the XPLS Series.
