UP-4XP ULTRACOMPACT LOUDSPEAKER
The UP-4XP ultracompact loudspeaker is ideally suited for
applications requiring a small, inconspicuous cabinet that
also delivers high sound pressure levels, low distortion, and
uniform directional control. The self-powered UP-4XP offers
exceptional audio performance in a compact package with
the advantages of a remote power supply. As a standalone
loudspeaker, the UP-4XP can be used for vocal reinforce-
ment, frontfill coverage, and delay coverage for under-bal-
cony applications. The UP-4XP can also be paired with an
optional subwoofer to create a full-range system.
The UP-4XP boasts a wide operating frequency range of
66 Hz to 18 kHz and a maximum peak SPL of 121 dB, with
very low distortion. The unit's high-frequency section
includes a 1-inch metal dome tweeter on a constant-direc-
tivity, high-frequency horn with a 100-degree beamwidth.
The low/mid-frequency section includes two 4-inch cone
transducers that work in parallel at low frequencies — deliv-
ering a combined acoustic output — with one of the drivers
rolling off at higher frequencies to prevent interference (due
to comb filtering effects) in the crossover region. The propri-
etary UP-4XP drivers, which are manufactured at Meyer
Sound's factory in Berkeley, California, are powered by three
channels of onboard power amplification that include an
active crossover, driver protection, and frequency and phase
correction circuitry.
