The S8T surface-mount loudspeaker, part of QSC's AcousticDesign™ series, (AD-S) is a professional-quality, 70/100 V, 8", 2-way, full-range speaker designed for a wide range of foreground and background sound reinforcement applications. Ease-of-installation is the driving principle behind this next generation of QSC small format, surface-mount loudspeaker. Innovations found on AD-S loudspeakers allow designers and integrators to quickly and easily specify and install a system. AD-S loudspeakers are also an excellent solution to fill ancillary loudspeaker needs as part of a larger installed sound system.

Housed in rugged and durable ABS enclosures for long-term durability, these units incorporate DMT™ (Directivity Matched Transition) technology which matches the low-frequency (LF) and high-frequency (HF) coverage at the crossover point. This ensures even coverage across the listening plane for smooth, coherent audio reproduction. The 1.4" diaphragm, 1-in exit compression driver delivers crisp, detailed high-frequency reproduction and when combined with the matched woofers, provides full bandwidth reproduction. To further enhance performance, tunings using QSC Intrinsic Correction techniques are available for Q-Sys and future QSC amplifiers. Moreover, the low saturation transformers offer premium performance on 70/100 V distributed audio lines.

The flexible mounting options will be appreciated by installers. Euroblock connectors allow pre-wiring of the system and the included X-Mount™ hardware enables the installer to mount the bracket and then simply lift the loudspeaker onto the mount and lock it into place. Moreover, the loudspeaker can attach to its mount on any plane to facilitate multiple deployment configurations.

AD-S loudspeakers can be easily mounted to any weight-bearing, flat surface. Knurled surfaces on the mount's pivot points ensure that the loudspeaker deployment angle stays fixed and will not slip over time. No special tools are required to install or adjust the loudspeaker angle. These models also feature M10 installation points for suspending the loudspeaker via eye bolts as well as mounting points for an optional yoke bracket.

These loudspeakers meet IEC60529 IP-54 for dust and splash resistance, and feature sealed input panels and powder-coated aluminum grilles for added weather resistance. Presenting a clean look, AD-S grilles are unadorned eliminating the need to cover obtrusive logo treatments. AD-S loudspeakers are available in either black (RAL 9011) or white (RAL 9010) and may be painted to match any décor.

To minimize impact and disposal fees at the job site, all AD-S loudspeakers are packaged in environmentally friendly, recyclable cartons.
