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.
