AcousticDesignTM Loudspeaker Features · 5.25", 2-way design--in a lightweight, contemporary styled multipurpose enclosure · agnetically shielded LF transducer--ideal for use near M video monitors ·Flexible ball mount assembly included--for convenient installation · 0/100 volt transformer versions available--for use with 7 distributed audio systems ·Optional yoke mount bracket available AD-S52 The QSC AcousticDesign AD-S52 is a full range, surface mount loudspeaker with sleek, contemporary styling that fits perfectly into multiple environments and applications including hotels, restaurants, convention facilities, and multimedia environments. The loudspeaker's low-frequency driver is magnetically shielded, making the AD-S52 perfect for use near video monitors. Available in black or white, these great sounding, weather resistant enclosures can be painted to match any specific decor. The AD-S52 is a high output, 2-way design incorporating a 5.25" weatherproof, LF transducer and a 1" neodymium tweeter. This exceptional loudspeaker carries the added benefit of built-in dynamic power protection--thus ensuring system reliability in the event of overload conditions. The AD-S52T models are equipped with a 70/100 volt matching transformer for distributed audio systems. There is a transformer tap switch on the rear panel for setting the power level of the loudspeaker. This switch may also be set for 8 ohm operation, bypassing the transformer completely--providing greater system flexibility compared to most competing products. The AD-S52 system package includes a ball mount assembly for convenient installation of the enclosure in a wide variety of orientations. If desired, the ball mount adapter's back plate can be removed, reducing the overall depth of the assembly and the footprint of the mount on the wall. Further, the assembly includes a weather resistant input connection cover to protect the 5-way binding post input terminals.
