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.

PS - There are other Q’s in speaker design and measurements so don't get them confused but I'm pretty sure this is what is meant here.

In designing the alignment of the lowest frequency driver a great deal of artistic license must be allowed given the tradeoffs of speaker size, maximum bass output and expected placement.

A speaker designed for near-wall or desktop placement in general wants a lower Q.

Yeah, it's pretty unusual.  They may be talking to the professionals who use these as near field studio monitors.  They want to let them know these are less punchy and more suitable for certain types of use.

when seeing Q of a loudspeaker mentioned as a generalization like that,

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