erik_squires is correct. The original LS3/5a had a Q of 1.2 which produced a bump in the mid bass. This was done to balance the bass to the rest of the sound spectrum since a flat speaker sounds lean if it's bass resonance is high like the LS3/5a. But the price of a high Q to balance the sound is increased overhang in the bass roll off and thus decreased definition in the bass.
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.
