The FH1566 is a 2way, high sensitivity, coaxial horn loudspeaker that provides a precise 60°x60° pattern with control to below 400 Hz, low frequency extension to 54Hz, and extremely high output using a single amplifier channel. Its 3.5inch voice coil, 15inch woofer combines interactively with a 4inch diaphragm high frequency compression driver to produce precise pattern control through the crossover range. The FH1566’s 35° vertically trapezoidal enclosure shape allows it to be mounted very close to ceilings with minimal effect on sight lines.
