Supertweeter for outstanding detail and clarity in highfrequencies without harshness. The ST324 is best suited for individual use in wide dispersion enclosures. The slot-shape horn design offers a wider throw 120 x 40 dispersion. The plastic injected housing is stable and durable. The phenolic annular diaphragm is long-lasting costeffective and more natural-sounding than metallic diaphragms. The use of high-temperature materials and adhesives improves power handling and produces exceptionally high acoustic output. A precisely engineered diaphragm structure and alignment mechanism for easy reliable cost effective repair in case of diaphragm failure. * Nominal impedance. . .8 ohms * Minimum impedance @ 6 700 Hz . . . 6 ohms * Power handling * Musical Program (w/ xover 5 000 Hz 12 dB/oct)1 . . . . 40 W * Musical Program (w/ xover 8 000 Hz 12 dB/oct)1 . . . . 80 W * Sensitivity (2.83V@1m) averaged from 3 to 10 kHz. . . . . . 103 dB SPL * Frequency response @ -10 dB. . . . . . . . . . . . . 3 500 to 18 000 Hz * Sound dispersion (H x V) . . . . . . . . . . . . . . . . . . . . . . . 120 x 40 degrees * Diaphragm material . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
