The M-Audio BX Subwoofer is a crucial part of any top-flight studio and is engineered especially for M-Audio Monitors.

The BX Subwoofer delivers deep, accurate bass response down to the lowest audible frequencies, picking up where your left/right studio monitors leave off. Recording professionals know that hearing the extreme low frequencies in music is essential for making accurate mixing adjustments and producing the best recordings. The BX Subwoofer easily fulfills this requirement in a powerful and compact package that won’t take up too much of your valuable studio space.

At A Glance:
  • 240-watt Class AB all-discrete internal amplifier
  • Variable 50-200 Hz crossover
  • 10” fiberglass/paper composite driver w/oversized magnet
  • High-temperature 2” voice coil
  • Constructed of resonant-free ¾” Medium Density Fiberboard (MDF)
  • 1” front and rear baffles
  • Subwoofer Bypass Footswitch
  • 180 phase reverse switch

The BX Subwoofer’s frequency response extends down to 20Hz (-3 dB), the lowest audible frequency. It uses the highest-quality components for no-compromise performance: a 10” fiberglass/paper composite driver with an oversized magnet and high-temperature 2” voice coil, powered by a 240-watt Class AB all-discrete internal amplifier with a variable 50-200 Hz crossover. The cabinet is constructed of resonant-free ¾” Medium Density Fiberboard (MDF) with 1” front and rear baffles, and is heavily braced to eliminate the extraneous cabinet vibrations that can rob a subwoofer of its impact and articulation.

Engineered Especially for M-Audio Monitors
Designed for use with the M-Audio M3, BX Carbon and BX D2 series, the BX Subwoofer delivers the deep bass response necessary to optimize your music, film and multimedia projects. Most of today’s personal audio systems can easily reproduce very low bass frequencies, so it’s critical that your audio production environment allows you to monitor and adjust those frequencies while you’re mixing. The included Subwoofer Bypass Footswitch is particularly useful when you want an instantaneous comparison of how your mix sounds with and without a dedicated subwoofer.

Rock-Solid Bass Performance
That’s why the BX Subwoofer carries a hefty 240 watts average continuous of totally discrete Class AB power for tons of headroom. “Headroom” is the amount of undistorted instantaneous power an amplifier can deliver in excess of its “continuous” or “average” RMS long-term power output rating. It’s what makes one amplifier sound “louder” than another, even when both have the same power rating. Class AB amplifiers have far more headroom than Class D digital amplifiers and an AB amp can usually play much louder and cleaner than a D of the same continuous power rating.

Active Crossover
The BX Subwoofer accepts two-channel stereo outputs from your mixer, audio interface or sound card. Your main L/R monitors connect to the subwoofer’s outputs. As stated above, the internal crossover network of the BX Subwoofer splits the signal at a user-chosen crossover frequency (between 50-200Hz), routing everything below to the sub and everything above the crossover point to the main L/R monitor speakers.
