The Subway is an active subwoofer from AER, a German loudspeaker maker producing in Germany since 1985. Its compact construction lets it fit into ordinary living spaces, and it is intended as a companion to the brand's Jazz and Custom loudspeakers.
Key specs that matter
The Subway uses an internal amplifier to drive a 38 cm bass driver with up to 210 W. The cabinet is a 40 x 40 x 40 cm cube.
Engineering and use context
The amplifier offers volume control, a variable frequency control adjustable from 40 Hz to 200 Hz and a switchable phase setting, which lets the Subway be matched to different main speakers. Finishes include white, black or transparent acrylic glass as well as wood veneer, so the cabinet can follow the look of AER's Jazz or Custom models.
