SELENIUM ST302

Bullet-shape Horn Supertweeter
SKU: ST302
Availability: Out of stock

Supertweeter for outstanding detail & clarity in highfrequencies without harshness.
The ST302 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 Degrees x 40 Degrees dispersion.
The plastic injected housing is stable & durable.
The phenolic annular diaphragm is long-lasting, costeffective & 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 & alignment mechanism for easy, reliable, cost effective repair in case of diaphragm failure.
