INTRODUCING THE UPQ-1P LOUDSPEAKER
The self-powered UPQ-1P wide coverage loudspeaker is a
member of the popular UltraSeries
®
family of loudspeakers.
The UPQ-1P loudspeaker’s extended low-frequency head-
room gives it a smooth sound over a wide operating fre-
quency range of 55 Hz to 18 kHz. With its easy-to-use and
versatile QuickFly
®
rigging, the UPQ-1P loudspeaker is
equally suited to touring, rental, and fixed installation appli-
cations. High power-to-size ratio and ease of use make it an
outstanding performer in concerts and corporate AV appli-
cations, and ideal for venues such as theatres, houses of
worship, ballrooms, and clubs. The UPQ-1P loudspeaker
produces a peak output of 136 dB SPL with low distortion
as well as exceptionally flat phase and frequency response
in a compact, vented two-way, trapezoid enclosure.
The UPQ-1P loudspeaker offers an extremely consistent
polar response, and is distinguished by its constant-Q horn
that provides 80-degree horizontal by 50-degree vertical
coverage (-6 dB points) and a gentle coverage rolloff that
extends uniformly out to its -10 dB points of 100 by 60
degrees.
The smooth and consistent performance of the horn is the
result of meticulous research in Meyer Sound’s anechoic
chamber, and it exhibits a remarkably consistent beamwidth
in both the horizontal and vertical planes across a wide fre-
quency range of 1 kHz to 18 kHz. In addition, the UPQ horns
deliver uniform attenuation for all frequencies outside the
specified beamwidth.
