Dual 15-Inch Aluminum-Magnesium Woofers and 1300W ICEpower DSP Amplification for Cinema-Grade Low-Frequency Impact

The Aperion Audio Bravus III B215 is a monumental dual 15-inch active cinema subwoofer engineered to deliver extreme low-frequency extension and dynamic pressure in large home theatre spaces. Powered by a high-efficiency 1300W RMS ICEpower Class D amplifier with advanced onboard DSP, it combines twin custom aluminum-magnesium alloy woofers with a convertible ported/sealed HDF cabinet design. Capable of producing linear, distortion-free bass response down to 15 Hz with customizable EQ presets, the B215 supplies visceral, room-shaking energy with reference-level detail.

• Dual 15-Inch Aluminum-Magnesium Alloy Woofers: Features twin 15-inch long-throw drivers engineered with light yet exceptionally rigid aluminum-magnesium alloy cones to prevent deformation during deep, high-excursion strokes.
• 1300W RMS ICEpower Class D Amplification: Utilizes high-efficiency ICEpower module technology to deliver 1300 Watts of continuous RMS power (2600W Peak) with minimal distortion and thermal compression.
• Onboard DSP with 3 Selectable EQ Presets: Includes integrated digital signal processing featuring Extend, Normal, and Flat EQ modes to tailor room gain and low-frequency extension to your exact listening space.
• Convertible Ported / Sealed Enclosure Design: Outfitted with a tuned rectangular bottom vent that minimizes airflow turbulence, plus an included custom foam plug to quickly convert the cabinet into a sealed alignment.
• Resonance-Free High-Density HDF Cabinet: Built with multi-layered, curved-side High-Density Fiberboard (HDF) and heavy internal bracing to eliminate cabinet flex and standing waves.
• Pro-Grade Balanced XLR & Unbalanced RCA I/O: Features line-level RCA and balanced XLR inputs and outputs to support seamless multi-subwoofer daisy-chaining and high-end pre-amp integration.
