About the BW3
The Lyngdorf Audio BW-3 is a compact active subwoofer designed for high-bandwidth, precision bass reproduction rather than only deep bass reinforcement. It uses an 8-inch long-throw aluminum-cone driver in a sealed MDF cabinet and a 400 W RMS Class-D amplifier, with a bypass mode that extends operation up to 800 Hz for Lyngdorf system integration. The BW-3 is intended for flexible placement and can be used upright or on its side; it was sold in black or white finishes with matching fabric covers.
