Design
The ASW 250 incorporates Boston Acoustics' proprietary BassTrac technology, a circuit designed to maximize bass output while preventing amplifier and driver overload. It uses Deep Channel Design (DCD) magnet structures and was engineered using Laser Vibrometer Scanning and Finite Element Analysis (FEA) to detect and eliminate unwanted resonances. The cabinet eliminates hardware on the front baffle and features rounded front edges, contributing to a clean aesthetic and improved structural integrity. Internal bracing is applied both vertically and horizontally, and the design follows the company's "Play Smart" approach to optimize performance and reliability.
Context
The ASW 250 is part of the A Series product line and is intended to be paired with other A Series speakers, which are sold separately.
