What exactly does the frequency response in a speakers specs. mean? And what should you be looking for in a speaker? I'm asking because I noticed the response in my surrounds are 80 Hz to 20 kHz, not sure what it means or if I'm missing something in sound quality.

Thanks Rick....

When trying to decide where to set the crossover, which range should I use for the Axiom speakers as they list two results, +-3db and +3-9db, one showing a much lower frequencies...?

I would select the +/-3dB rating. When I was searching around for what crossover point to use for my M80s I read that going 10Hz up from the +/-3dB rating is a good place to start.

A change of 3 dB is barely perceivable, and 10 dB change is twice or half as loud. A +/- 3 dB spec is best to go off of, as it is a smaller tolerance to ruler flat linear frequency response.

A speaker frequency spec of +3/-9 dB gives you an idea of the roll off at the bottom end. The lower range at -9 dB is just a little over half as loud as the rest of the upper frequencies.
