THE UPQ-D SERIES LOUDSPEAKER
Meyer Sound’s UPQ-D Series loudspeakers evolved from
the UPQ-1P and UPQ-2P product line, optimized using the
advanced amplifier and processing technology that made
the LEO
® family an award-wining product line. The series
includes the following loudspeakers:
•
UPQ-D1, which has a Constant-Q horn with
-6 dB points at 80° horizontal x 50° vertical
(-10 dB points at 100° horizontal x 60° vertical)
•
UPQ-D2, which has a narrow symmetrical coverage and
a Constant-Q horn with -6 dB points at 50° x 50°
(-10 dB points at 60° x 60°)
•
UPQ-D3, which has a wide symmetrical coverage and a
Constant-Q horn with -6 dB points at
80° horizontal x 80° vertical
(-10 dB points at 100° horizontal x 100° vertical)
All of the UPQ-D series feature:
•
An innovative, highly efficient Class D amplifier with
reduced current draw that reproduces any sound with
linearity over a wide dynamic range
•
Optimized frequency and phase response
characteristics
•
Lightened cabinet weight
•
A redesigned cabinet that retains the original size, grille
frame, and rigging options of previous UPQ products
Each UPQ-D Series loudspeaker offers extremely consistent
polar response and gentle coverage rolloffs that extend
uniformly out to their 10 dB points. The smooth and
consistent performance of all the horns is the result of
advanced computer modeling combined with meticulous
research in Meyer Sound’s anechoic chamber. They also
exhibit remarkably consistent beamwidth in both the
horizontal and vertical planes. The UPQ-D Series horns
deliver uniform attenuation for all frequencies outside the
specified beamwidths.
In addition to the Constant-Q horn, the loudspeakers each
feature one low frequency 15-inch neodymium magnet cone
driver and one 4-inch diaphragm compression driver, both
designed and manufactured at Meyer Sound’s Berkeley,
California headquarters. The UPQ-D1 and UPQ-D3 are
suitable for a range of sound reinforcement applications
including as front-of-house main loudspeakers in small- to
mid-sized venues, or as fill loudspeakers in larger systems.
