What does Q mean in speaker specifications?

I have never seen that listed before on any speaker. Can you explain what the Q means on these Falcon speakers? THX

 

 

Falcon Acoustics is pleased to announce the re-introduction of the Falcon Acoustics Q7 “Complete@Home” Loudspeaker system. Designed by Malcolm Jones and sold by Falcon for many years, the updated Q7 features the same Falcon B110 and T27 drive units as used in the Falcon LS3/5a in a specially extended LS3/5a-type cabinet to produce an optimum Q=0.7 system with extra bass compared to the LSA3/5a (+2dB @ 50 Hz). Factory built options supplied built by Falcon, fully checked and tested are available.

Here is simple/nutshell info on such from a speaker manufacturer.

Having used various vintage single driver speakers, mated with various tube/SS amps, for the past 20 years (as well as different enclosures - including open baffle) I do pay attention to the combined QTS measurements (and/or guessed values based upon listening/experimentation) of the drivers I've owned/used/consider'd.

Damping factor (low values) of the amps I've used/use is also a consideration.

Dyna:

Do you have documentation for the 1.2 "Q" measurement?

Having owned Rogers Ls3/5a's for 1979-1986 I find that spec hard to comprehend (considering the cabinet size).

Yes, they did had a mid-bass hump - making them difficult to properly mate with subs (including their non-sub AB1's which I also used).
