Introduction AcousticDesign series is a line of premium surface-mount loudspeakers intended for permanent installation applications. Housed in rugged ABS molded enclosures, each loudspeaker (except the S12) features a 70/100V transformer for use with distributed-audio lines. The unique X-Mount™ Bracket and Euro-style connector, supplied with each AcousticDesign loudspeaker, are designed for maximum flexibility and a quick install. Featuring a knurled ball-mount and discrete angle deployment marks, installers can set loudspeaker deployment angles quickly and securely. The Euro-style connector allows pre-wiring of the system and when combined with the quick “snap-on” deployment of the loudspeaker to the mount, installation is completed in a fraction of the time required versus competitive models.
