Is there a midbass model (without the whizzer cone)?

Guess the buildhouse is easy to tell:

On a 2" coil? Unless someone has defied the laws of physics, that doesnt stack up as being that impressive You'll smoke a 2" coil with a mere 3-400 Watts, easy. Regardless of cooling efficiency of the motor.

Its sensitivity is off too. 98dB is at 4ohms, 1W@1M. Works out to around ~90-92dB @2.83V

And to me, the Fs is to high, you wont be getting any midbass out of that one.

Plus I thought the Beyma buildhouse was in China?
