8" Two-Way Surface Mount Loudspeaker with 70/100V Transformer and 8Ω bypass
The AcousticDesign Series S8T Surface-Mount Weather-Resistant Professional 2-Way Loudspeaker from QSC is a full-range unit suitable for a wide variety of foreground and background sound reinforcement applications such as restaurants/retail outlets, audio-visual, educational, healthcare facilities, casinos, offices, worship facilities, and ancillary support in larger systems. The unit comes with a low saturation transformer that offers premium performance on 70/100V distributed audio lines.
Housed in a rugged yet sleek ABS enclosure for long-term durability, the S8T 2-way loudspeaker employs DMT (Directivity Matched Transition), which matches the LF and HF coverage at the crossover point. This ensures even coverage across the listening plane for smooth, coherent audio reproduction. The 1.4" diaphragm, 1" exit compression driver on the S8T delivers crisp, detailed, high-frequency reproduction and when combined with the matched woofers (sold separately), provides full bandwidth reproduction.
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.
The loudspeaker unit can easily be 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. The S8T unit features M10 installation points for suspending the loudspeaker via eye-bolts as well as mounting points for a yoke mount bracket (sold separately).
The speaker meets IEC60529 IP-54 rating for dust and splash resistance and features sealed input panels and powder coated aluminum grilles for added weather resistance.
