In the example that I used, the frequency response of the speaker can be reported as:

56.5Hz 12,500Hz, +/-3dB

or

40.0Hz 16,500Hz, +/-6dB

Obviously, the +/-6dB frequency response looks more impressive, but that is misleading.

There are some manufacturers that go to the extreme and state in their literature that the frequency response of their speaker/subwoofer is 25Hz @ -10dB.
I see. Thanks
