This ADS tree-way speaker system, model L630, features a very high quality dome midrange that provides unusual clarity and openness in the human voice, according to the company. An acoustic suspension soft-dome 1-inch tweeter with a single-layer, hightemperature metal voice coil, has a magnetic flux density of 1,65 teslas (16,500 gauss), and an operating frequency range from 4,000 Hz to 25,000 Hz. The acoustic suspension soft-dome mid-range 1-1/2 inch driver with high temperature metal voice coil has a magnetic flux density of 1,5 teslas (15,000 gauss), the same magnetic flux as the tweeter, and an operating frequency range from 650 to 4,000 Hz. The long-excursion woofer is 10 inches in diameter, with a 1-1/2 inch high-temperature voice coil and shallow Stifllite cone. The magnetic flux density is 0,90 Teslas (9,000 gauss0, the magnetic flux is 850,000 nW, he free air resonant frequency is 20 Hz, and the operating frequency range is 20 to 650 Hz. The overall speaker system has a frequency response of 33 to 20,000 Hz (±3 dB) or 22 to 22,000 Hz (±5 dB).
