There's some explanations of the Walsh driver characteristics at Ohm's website - https://ohmspeaker.com/technology/

Unsound maybe you found this. With much info contained. I would be interested in seeing how the driver is terminated on the edges so some polarity of the signal does not return into the path of the next uncoming signal. Same thoughts on any of the Walsh drivers the inside and outside of the cone must react with some signal inversion. Tom. https://www.bendingwaveusa.com/technology/ |
@tomthiel, As I understand it, though the Walsh driver is conical, the bending wave travels faster than the speed of sound, thus being able to produce step and square wave response indicating time preservation. The omnidirectional dispersion, while perhaps tricky for small room placement, is capable of charging the room rather uniformly. The original Walsh drivers were a difficult balance in that they required quite a bit of power yet could be damaged if overdriven. Modern versions claim to alleviate these issues, though extreme SLP’s still seem to be the forte’ of other designs, distribution seems somewhat limited, and they are not inexpensive. I have not heard any of these type of drivers in decades. I would welcome the opportunity! |
