Speco Technologies’ Multi-Application Series was designed to make the contractor’s work as easy and time-efficient as possible. Our all-in-one unit comes pre-assembled with back can and mounted transformer. It features a quick-flip 70 or 25 Volt selector switch and an easy-select transformer wattage dial. The choice of 8 or 9 individual wattage tap settings covers a complete range of uses. This flame-retardant ABS unit also comes with insulated wires, has an attached metal seismic safety loop and built-in easy mount tabs for securing the unit. The MA Series is the ideal, all-purpose value speaker covering a wide range of commercial applications. The furnished 8 Ohm tap selector also means the speakers can be kept on-hand for unexpected residential installation needs.
