Active Subwoofer by M-Audio

The M-Audio BX Subwoofer delivers deep, accurate bass response down to the lowest audible frequencies (20Hz or -3 dB), in a powerful and compact package. Here at The Disc we’d recommend it as an indispensable part of a high-performance monitoring system to provide great sound over the entire audible spectrum. 

The active crossover splits the signal at your chosen frequency (between 50-200Hz), routing everything below that point to the sub, and everything above to the main L/R monitor speakers, allowing the entire system to play with less strain and distortion, so you’ll get cleaner sound and make better mixing decisions. The HP/LP filters (24 dB/oct) significantly improve your system’s precision, limiting the amount of “overlap” between the subwoofer and the satellites. With regard to speaker location, the crossover also makes it possible to tailor the bass response in your monitoring environment in order to achieve the most accurate acoustic response, in both studio and home theatre applications. As such, you can choose a higher crossover frequency if the subwoofer is placed reasonably close to the L/R monitors, or a very low crossover frequency if the sub is located far away from the L/R monitors, which means sound becomes more “localisable” as frequency increases, while very low bass is non-directional. 

The BX Subwoofer features two XLR balanced/unbalanced inputs, two TRS balanced/unbalanced inputs, and two unbalanced RCA inputs. There are also two XLR balanced/unbalanced outputs and two TRS balanced/unbalanced outputs. It features volume/gain controls, a phase inverse switch for a seamless frequency response, variable 50-200 Hz crossover control to blend perfectly with L/R monitors of all sizes, and a subwoofer bypass footswitch that provides a comparison of how your mix sounds with and without a subwoofer. By plugging in the footswitch, you can control this function as you’re playing back your material—even from across the room.

The BX Subwoofer features a 10” fiberglass/paper composite driver with an oversized magnet and high-temperature 2” voice coil, powered by a 240-watt Class AB internal amplifier with a variable 50-200 Hz crossover. The cabinet is constructed of resonant-free ¾” MDF with 1” front and rear baffles, and is heavily braced to eliminate the cabinet vibrations that can rob a subwoofer of its impact and articulation. The BX Subwoofer produces a clean acoustic output and deep, articulate low-frequencies that add body to your sound.
