Each loudspeaker (except AD-S12 and AD-S112sw) is housed in a durable ABS enclosure and features a 70/100V transformer for use in distributed audio lines. The unique X-Mount™ brackets and Euro plugs included with every AcousticDesign loudspeaker are designed for maximum flexibility and quick installation. Featuring a knurled ball-mount and discreet angle deployment marks allow installers to quickly and safely adjust the speaker's deployment angles quickly and securly. The Euro-style connector allow for pre-wiring of the system, which, combined with quick snap-on deployment of the speakers into the mounts, allows installation to be completed in a fraction of the time of competing models.
