The AD-S8T features a high quality 8” weather-treated paper cone woofer on a 2” voice coil. A carefully selected 1” compression driver perfectly matches the sensitivity and performance of the woofer for outstanding full-range reproduction.

The even, accurate frequency response of the AD-S8T is aided by a 60-watt low-loss, low-saturation transformer with selectable taps, including an 8Ω bypass. To enhance weather resistance, the rotary tap selector is located on the back of the enclosure, protected by a weather grommet. With rugged ABS enclosures, sealed input panel covers, and powder-coated aluminum grilles for weather resistance, the AcousticDesign™ surface mounted series exceed IEC60529 IP-54 ratings for dust and splash resistance.

Installers will appreciate the award-winning X-Mount™ system included with each AD-S8T speaker. This ingenious mounting solution achieves unprecedented ease-of-installation in horizontal, vertical, wall, or ceiling deployments. Knurled surfaces at the pivot planes ensure the load will not drift or sag over time. Articulation marks allow preconfiguration of the X-Mount while on the ground with no special tools required. Once secure, the loudspeaker installs in seconds, allowing the installer to work safer, smarter, and faster with repeatable results.
