Product Description

Supertweeter for outstanding detail & clarity in high frequencies without harshness. The ST300-SLF* may be used individually in lower power systems or arrayed for increased coverage & SPL in higher power systems. The bullet-shape horn design offers a longer throw 40 x 40 dispersion. The cast aluminum housing is stable & durable. The phenolic annular diaphragm is long-lasting, costeffective and more natural-sounding than metallic diaphragms. The use of high-temperature materials & adhesives improves power handling & produces exceptionally high acoustic output. A precisely engineered diaphragm structure and alignment mechanism for easy, reliable, cost effective repair in case of diaphragm failure. *ST300-SLF: Product without Selenium / Professional logo on the face plate. * Nominal impedance. . 8 OHMS * Minimum impedance @ 8,500 Hz . 6.9 OHMS Power handling * Musical Program (w/ xover 5,000 Hz 12 dB/oct)1 . 50 W * Musical Program (w/ xover 8,000 Hz 12 dB/oct)1 . 100 W * Sensitivity (2.83V@1m) averaged from 5 to 15 kHz. 108 dB SPL * Frequency response @ -6 dB. 3,500 to 20,000 Hz * Sound dispersion (H x V) . 40 x 40 degrees * Diaphragm material . .
