Glad to see this wasn't another post about the Royal Device concrete horn subwoofer.

The one you posted sounds like a brute; I wish they would have included some pictures.

its probably just 4 tumult -clones

for 20,000$ i expect that sort of quality.

looks like a bandpass

Diameter 390 mm Resonant frequency 40 Hz
Thermal power 300 (continuous RMS) Qt 0.18
Maximum displacement 30 mm BL product (Tm) 25

strange. a 16hz subwoofer using an fs=40hz .

the low qts is not suprising

read the tech part of PAM

I loved this line from the tech paper :

"Further, as the designs utilised the propagating medium (air) the result scaled with changes in ambient conditions also. It was as if nature had intended this approach to be followed."

Has anyone been able to find the patent for this? I tried looking it up but I don't really know what I'm doing in that area. I'd like to learn more about the PAM technology.

I think you're in luck. There isn't a patent yet on using air as the propagating medium. Just don't mention that to Amar
