Product Details
These speakers are shipped complete with a ‘DC Blocking Capacitor’ to permit electrical supervision of the audio distribution circuit. Use the 964 series for 25 Vrms circuits; the 965 series for 70 Vrms circuits. The large eight-inch speaker cone offers a wide frequency response to improve audibility and intelligibility. Wattage taps from 1/2 to 4 watts provide on-site flexibility where higher or lower dB output is desired. Wattage tap selection is easy; just move the slide-on spade connector on the speaker’s terminal block.
