The PHL 1120 is the highest sound quality high efficiency midrange available. The parameters have been optimized for the flattest response in direct radiation applications. It has a flat latex foam surround for smooth frequency response and the lightest weight. Crossover above 300 Hz at 12 dB per octave and use up to 4000 Hz. For pro sound use a 6 liter sealed box for -3dB at 176 Hz. For HiFi use a 10 liter sealed box for 150 Hz resonance frequency. 200 watt amplifier = 118 dB.
