Environment-resistant EN54-24 certified SM Series loudspeaker systems offer quality sound reproduction and contemporary styling in a compact enclosure. System components consist of a highly efficient woofer section and ferrofluid cooled, polymer reinforced linen composite dome high frequency device. This design provides smooth, even sound coverage (120° conical). The high frequency section is symmetrical, for equal coverage in both vertical and horizontal cabinet mounting positions. High frequency component protection is provided by the AtlasIED PolyGuard™ protection circuit. The SM63TEN includes an internally mounted 32-Watt 70.7V/100V line matching transformer with screwdriver adjustable tap selection for use in distributed sound applications. The tap selection switch also includes a transformer bypass setting for direct coupled 8Ω operation.
