.707 is said to be the correct "Q" with respect to damping. A higher Q indicates a woofer that is underdamped (loose) while a number lower than .707 indicates an overly damped woofer. I don't have the scientific background to tell you what the number means but .707, 1.41, 2.82, etc. are numbers
commonly seen in physics along with 3.14 (pi). My guess is
that with a Q of .707, the woofer cone moves when it should and stops when it should.
