Key Features
I Advanced Composilite™ Carbon Fiber
Enclosure—reduces passive enclosure losses
(resulting in greater sonic accuracy), offers
reduced weight, and is highly weather resistant.
ACE 1250
I 12-inch, 2-Way System—in a lightweight, multi-
purpose enclosure; fully equipped with certified
rigging hardware for improved safety margins
plus reduced shipping and handling costs.
I Spherical Waveguide—mated with 1.5" exit
neodymium compression driver, delivers true
constant-directivity performance, 75° nominal
coverage pattern, and reduced throat distortion.
I Versatile Shape—works as a floor wedge,
side fill, or in small front-of-house clusters.
I High Power Handling—a 4-inch LF voice coil
and 4-inch HF voice coil handle 600W continuous
AES power. With 96 dB efficiency, peak SPL
can reach 130 dB.
I QSC DSP Downloads— for QSC-powered
systems using the DSP-3 programmable
processor, a growing selection of custom
tailored downloads offer virtually perfect
“dialed-in” performance right out of the box.
The QSC-ACE 1250 Composite Loudspeaker is a
full range speaker system that delivers exceptional
sound quality and high SPL in a lightweight, all-
weather carbon fiber enclosure. It makes an
excellent choice for front of house arrays, delay
or downfill clusters, high-level dance systems,
and low profile stage monitoring systems.

Configuration
Two way, ported enclosure
Two way, ported enclosure
The two-way, ported enclosure comprises a
1.5" exit neodymium compression driver coupled
with a high frequency spherical waveguide that
has true constant directivity performance. This
spherical waveguide minimizes throat loading and
distortion issues commonly associated with
conventional high frequency horns. A powerful 12"
LF transducer handles 600 watts of continuous
power and provides smooth response through the
crossover point. With a 75° nominal coverage
pattern, multiple units can be splayed together to
meet expanded coverage and SPL requirements.
The QSC-ACE 1250 WR employs a passive
crossover that can be bypassed for bi-amplified
use. The QSC-ACE 1250 AWR is designed for bi-
amplification only and requires an external crossover.
QSC-ACE enclosures incorporate Composilite™,
a patented core composite technology that yields
superior acoustic properties, lighter weight, and
outstanding weather resistance compared to
conventional enclosure materials. Multiple skins
of carbon fiber are layered over a phenolic honeycomb
core to form a rigid, seamless enclosure. The
extreme stiffness of composite construction prevents
flexing of the enclosure walls, significantly
reducing transmission loss due to wall vibration. The
result is reduced cabinet resonance, increased
low-frequency output, and greater sonic accuracy.
Furthermore, the enclosure’s light weight
translates to safer rigging and reduced handling
costs. Installation accessories and array kits are
readily available.
