Specifications Bandwidth: 19 Hz - 25 kHz ...?

I've seen this specification used on some speakers. While I understand what it means, my question is - what practical good is this specification in terms of how the speaker might perform?

If it's -10db at 19hz, it's pretty useless and while 19hz may not matter, what is the response at 25-30hz where one might care?

Don't let the bench testers fool you, The broader the range the better. Even though human ears arn't supposed to hear beyond like 17Khz. Our hears can still tell something is going on in those upper freqs.

Phil..I don't disagree with you at all. '...broader is better...' I just don't understand the value of specifying bandwidth in an unqualified manner - i.e. bandwidth versus frequency response. How do you measure bandwidth? On axis at 1 meter and what is the response in db?

My premise is that the manufacturer is playing specsmanship and these speakers if spec'd +/- 1db or even +/- 3db would look something like 25Hz - 20kHz or even worse.

Agree with you both: Todd's opine that wider bandwidth is more desirable along with R's assertion that unqualified half-spec's don't mean a whole lot to anyone.
As always; caveat emptor
