Allowing you to extend the frequency response of your M-Audio or other monitoring system down to 20 Hz, the BX 240W 10" Subwoofer from M-Audio features a 10" composite woofer and sweepable crossover frequency between 50 and 200 Hz, allowing you to customize the unit's performance to match your system and needs. It has both stereo XLR and TRS inputs and outputs for a variety of connectivity options, and is constructed of resonant-free materials and heavily braced to reduce vibrations.
For quickly comparing bass performance with and without the subwoofer engaged, the BX subwoofer can be turned on and off via the included footswitch. Its phase inverse switch allows for proper phase alignment regardless of where you place the unit.
The BX Subwoofer empowers you to do just that. When paired with any M-Audio studio monitor, the BX Subwoofer becomes part of a monitoring system that provides accurate sound over the entire 20 Hz to 20 kHz audible spectrum. Although designed to be used with M-Audio monitors in mind, the BX sub will enhance the low-frequency performance of any brand of high-quality near-field monitor
This is because the active HP/LP crossover in the BX Subwoofer acts as a "traffic cop," directing low frequencies to the subwoofer and only letting those frequencies above the user-chosen crossover point to go to the satellite monitors. When the satellites are relieved of the burden of trying to reproduce the deep bass with their modest 5" woofers, they can play at much louder levels with markedly lower strain and distortion. The entire system now plays cleaner, louder, and with greater detail, which means you'll get cleaner audio information and make better mixing decisions.
The steep 4th-order HP/LP filters (24 dB/oct) can improve your system's overall fidelity because they limit the amount of "overlap" between the subwoofer and the satellite, thus minimizing phase-related frequency response cancellations and other crossover-induced anomalies. This assures that each component only has to deliver frequencies to which it is ideally suited: deep bass for the BX Subwoofer, and mid-bass/midrange/treble for your near-field monitors.
The variable 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 theater applications. For example, to minimize "localizing" on the sub (detecting the origin of the sub's sound by ear, which destroys any semblance of a believable sonic image), you can choose a higher crossover frequency if the subwoofer is 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. Sound becomes more "localizable" as frequency increases, while very low bass is non-directional. Therefore, you can see how a widely-variable 50 to 200 Hz crossover-like in the BX Subwoofer-really opens up your system placement options
The 10" driver features an oversized magnet for higher sensitivity ("efficiency") and a high-temperature, long-throw voice coil, delivering maximum low frequency output and optimized power handling.
The cabinet is made of 3/4" vinyl-clad MDF with 1" front and back baffles, serious internal bracing and a flared rear bass-reflex port to minimize audible air turbulence and optimize low frequency output. The fiberglass/paper composite driver provides exceptionally accurate bass response, resulting in deep, articulate low-frequency output that adds stunningly lifelike body and weight to any program material
