QFlex 48
Technical Data Sheet
Product description
The acoustical principles and physics that govern beam-steering loudspeakers are well established
and documented, and therefore not subject to patents. However, the specics of design, engineering
and manufacturing are critical, since it’s the implementation of the principles that will determine
sound quality, beam control range, uniformity of dispersion, and product reliability. On all these
counts, Tannoy’s QFlex range denes the global standard for column array beam-steering technology.
We determined that full-range beam-steering would be a prerequisite from the outset, rather than
placing emphasis only on vocal regions as with competitive products
In the most difcult acoustical environments – whether in traditional cathedrals or vast ultra-modern
airport terminals – QFlex loudspeakers precisely control directivity in the vertical axis, resulting
in optimal venue coverage and the best possible direct-to-reverberant ratio. Acoustic output
is precisely aimed where it needs to be delivered, greatly reducing reections from hard
surfaces – even when the QFlex column must be mounted well above audience level. Whether
the audio program is music or critical voice announcements as part of a life safety or mass
notication system QFlex will provide exceptionally high voice intelligibility and full-bodied, natural
music reproduction. Also, compared to implementing acoustical treatments or even deploying
competitive beam-steering loudspeakers, a QFlex solution will result in cost savings coupled
with superior performance.
