Designed to add high output, high frequency response, and dispersion to any audio system, the Earthquake Sound BT90S Titanium Super Bullet Tweeter provides precise imaging of audio program material over a wide range of frequencies and dynamic ranges. It may be used separately in lower power systems or arrayed for expanded coverage and SPL in higher power systems. Additionally, the BT90S provides a controlled conical dispersion for reduced reflections thanks to its bullet-shaped structure. High-temperature materials enhance power handling, allowing the BT90S to produce an incredibly high acoustic output. Its durable die-cast aluminum housing, ferrofluid cooled voice coil with Kaptop former, in-line crossover capacitor, and horn-loaded structure provide dynamic and detailed sound reproduction to give any audio system concert-level output capability.
