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

In other words you can say its meaningless when manufacturers post ratings with -6 db or -10 db, right?

They are not technically wrong. They are just exaggerating the performance of their speakers/subwoofers.

Hello BD I read a really good article about frequency response of speakers the other day that helped me understand them a bit. I was wondering if could share the link here so it could help others like me. What do you think?
