difference between +3 -6db spec.

[jbl]

Hi all;

While going through my 4343 catalogue, I noticed that the frequency response was listed as "+3 -6 db" instead of the usual +/- xdb. Anyone out there know why?

This just means that the response in the measured frequency range varies within +3dB and -6dB.
Maybe it looked better this way?
