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.

they are likely (hopefully) referring to “total Q”

Total Q of a driver (only) is two parameters- mechanical and electromagnetic …

Dont mistake this for “total system Q” which incorporates an enclosure (and it’s volume/ port size length  (or sealed).
