Key Features
-
High-Power Class-D Amplifier
Built-in efficient amplifier delivers clean, continuous power with minimal heat generation. Rated power from 100W to 500W RMS (depending on model) ensures headroom for dynamic bass peaks.

Precision Low-Frequency Driver
Custom-designed long-throw woofer (8", 10", 12", 15", or 18") with a high-excursion rubber surround and stiff woven cone. Die-cast aluminum frame guarantees stability under high output.

Wide Frequency Response
Typical response: 25Hz – 150Hz (±3dB). Deep extension down to 25Hz reproduces subsonic bass notes without roll-off.
