Re Beyma 21" Woofer 21PW1400/Fe PW Series.
As a matter in interest only, how far up the range could this woofer be taken?
Usually such a transducer would not be taken much above 2-300Hz but it seems quite smooth further up.
Quotes range is up to 1.8Khz, frequency response is quite smooth up to that range. However no impulse response plots are available so there is no way of knowing how it would perform, distortion looks quite reasonable however.

Cone brake-up is starting at 1000Hz, so max usable frequency is bellow 600-700Hz. Further, if you factor in dispersion, max frequency is below 600Hz. Also, third harmonic distortion is rising above 350Hz.
So if we account all gremlins - max usable frequency is 300Hz.
