Key Features

■

Advanced Composilite™ Carbon Fiber

Enclosure

— reduces passive enclosure losses

(resulting in greater sonic accuracy), offers

reduced weight, and is highly weather resistant. 

■

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.

■

Spherical Waveguide

—mated with 1.5" exit

neodymium compression driver, delivers true

constant-directivity performance, 75° nominal

coverage pattern, and reduced throat distortion.

■

Versatile Shape

—works as a floor wedge,

side fill, or in small front-of-house clusters.

■

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. 

■

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.

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.
