Boston Acoustics ASW 250
A 250-watt peak powered subwoofer with a 10-inch down-firing driver and proprietary BassTrac technology
Overview
The Boston Acoustics ASW 250 is a powered subwoofer from the company's A Series. It is meant to work with compatible speakers in a home audio system. The 10-inch Deep Channel woofer is mounted down-firing, and a 100-watt RMS (250-watt peak) amplifier drives it. Boston went after clean, controlled bass with a mix of mechanical and electronic tricks, including resonance control and overload protection circuitry.

Design
The ASW 250 uses Boston Acoustics' proprietary BassTrac technology. It's a circuit that squeezes out as much bass as it can while keeping the amplifier and driver from overloading. The driver has Deep Channel Design (DCD) magnet structures. Laser Vibrometer Scanning and Finite Element Analysis (FEA) were used to find and eliminate unwanted resonances. The front baffle has no hardware on it, and the front edges are rounded. That gives a clean look and a stronger structure. Internal bracing runs both vertically and horizontally. The design follows the company's "Play Smart" approach to performance and reliability.
Context
The ASW 250 belongs to the A Series line. It is meant to be paired with other A Series speakers, which are sold separately.
