## Overview

The Selenium ST400TRIO is a high-performance super tweeter designed for exceptional clarity and detail in high-frequency audio. With an 8-ohm nominal impedance and a frequency response range of 4,000 to 20,000 Hz, it is ideal for both low and high power audio systems. Its aluminum construction ensures effective heat dissipation, while the innovative bullet-shape horn design provides a wide sound dispersion of 40° x 40°. The phenolic diaphragm offers a natural sound profile, making it a reliable choice for audiophiles seeking quality and durability.

## Description

Super tweeter for outstanding detail & clarity in high-frequencies without harshness. The St400 TRIO may be used individually in lower power systems or arrayed for increased coverage & SPL in higher power systems. The base & diffuser are constructed of aluminum contributes to better heat dissipation of the coil moves, w/finish machining of diamond (diamond tool) & varnished. The bullet-shape horn design offers a longer throw 40 Degrees x 40 Degrees dispersion. The phenolic annular diaphragm is long-lasting, cost-effective & more natural-sounding than metallic diaphragms. The use of high-temperature materials & adhesives improves power handling & produces exceptionally high acoustic output. Together w/magnetic ring of aluminum ensuring a high-definition & efficiency across its fixed playback. Connectors w/quick couplings * Nominal impedance: 8 ohms * Minimum impedance at 9,400 Hz: 7.8 ohms * Frequency response at -10 dB: 4,000 to 20,000 Hz * 40 x 40 degrees sound dispersion * Recommended maximum program power while using crossover at 8000 Hz: 300 Watts * Recommended maximum program power while using crossover at 5000 Hz: 200 Watts * Diaphragm material: Phenolic * Voice coil diameter:.42 (1.6) mm (in)
