Supertweeter for outstanding detail and clarity in highfrequencies without harshness. The ST302 may be used individually in lower power systems or arrayed for increased coverage and SPL in higher power systems. The bullet-shape horn design offers a longer throw 40° 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.
