Selenium St400trio Super High Frequency Tweeter

This item is brand-new, factory sealed.

Super tweeter for outstanding detail and clarity in high-frequencies without harshness. The st400 trio may be used individually in lower power systems or arrayed for increased coverage and spl in higher power systems.
the base and diffuser are constructed of aluminum contributes to better heat dissipation of the coil moves, with finish machining of diamond (diamond tool) and varnished.
the bullet-shape horn design offers a longer throw 40 x 40 dispersion.
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.
together with magnetic ring of aluminum ensuring a high-definition and efficiency across its fixed playback.
