Selenium Loudspeakers Usa ST304 Super tweeter for outstanding detail & clarity

Super tweeter for outstanding detail and clarity in high frequencies without harshness. The ST304 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 400 x 400 dispersion. The plastic injected housing is stable and durable. The phenolic annular diaphragm is long-lasting cost- effective 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.
