Two points:
1) Doppler distortion:
Re ribbon: Doppler distortion, which results in intermodulation distortion, doesn't really go into effect until around 180Hz. We crossover at 200Hz for that reason among others, so it is not a factor for the ribbon.
Re woofers: Yes, doppler distortion is a consideration, but there is minimal doppler distortion from our planar hybrid woofers because of the actual technology employed. This is linked to how the planar membrane itself is constructed and excited -- I can't say anything else because to do so would reveal proprietary intellectual property. Also, remember, any distortion is shared among 4 woofers -- overall distortion will be perceived as less for that reason vs a single driver topology. Finally, the fact that the woofer's excursion is 2 inches maximum doesn't mean that it is out there flapping around at the limit all the time, if ever. Most of the time, even at very impressive spl's with very demaning source material, the 4 woofers are cruising along at levels way below maximum performance levels, thanks to their synergistic design. At very high spl's, there is of course increased distortion, but the signal to noise ratio saves the day -- when the distortion is relatively high overall, it is still not relatively high compared to the signal. The Gilmore speakers, especially the model 2's, can play bass louder and cleaner than any other dipole or planar for sure and any home audio dynamic speakers we know of.
Concerning a forum participant's concerns that these speakers should not be called planars -- I think that the silliness of this perspective has already been pointed out by other forum participants. Let me add three other considerations. There is no box,the panel is flat and the radiating elements are all on the same plane -- thus the term planar.
Thanks again.
