The active M-Audio SBX10 subwoofer gives your monitoring system some serious low end. The SBX10 delivers tight, clean bass response down to 20Hz ”revealing the extreme low frequencies in your music so you can make accurate mixing decisions. With a 10" fiberglass/paper composite driver, a 240W all-discrete internal amplifier, and a variable 50-200Hz crossover, the SBX10 subwoofer delivers unbeatable performance in a compact chassis”great for studios where space is tight. An oversized magnet, high-temperature voice coil, high-density cabinet and a full complement of inputs are just some of the additional components that round out this high-quality M-Audio subwoofer. The SBX10 even includes a bypass footswitch, so you can easily judge how mixes will sound with and without a dedicated subwoofer. The M-Audio SBX10 makes a great addition to any studio monitor setup.

Engineered Especially for M-Audio Monitors
Designed for use with the M-Audio CX and BX Deluxe series”or most other studio monitors”the SBX10 active subwoofer delivers the kind of bass response necessary for music, film, and multimedia projects. Since today's personal audio systems are designed to reproduce very low bass frequencies, it is critical that your audio production environment allows you to monitor and adjust those frequencies while you are mixing. When paired with either the M-Audio CX or BX Deluxe studio monitors, the SBX10 becomes part of an integrated system that provides accurate monitoring for the entire 20Hz to 20kHz spectrum. Of course, it enhances most other direct-field monitors as well.

Don't Strain Your Speakers or Your Ears
Studio monitors like the CX5 and BX5a Deluxe are designed to work well as full-range monitors. Yet when they reproduce extremely bass-heavy material at high volumes, it can be both taxing on the speakers and fatiguing to the listener. When they're used in tandem with the SBX10, however, the system can comfortably reproduce full-range signals at higher levels without stressing the components.

Active Crossover for Two-Channel Setups
The SBX10 subwoofer accepts the two-channel stereo outputs from your mixer, audio interface, or sound card, and your main monitors connect to the subwoofer's outputs. The internal crossover network of the SBX10 splits the signal at a user-defined crossover frequency (50-200Hz), routing everything below it to the internal sub and everything above it to the main speakers. This significantly improves fidelity because the components aren't tripping over each other to reproduce the same frequency ” and each only has to deliver frequencies to which it is ideally suited. The variable crossover makes it possible to tailor the bass response in your monitoring environment in order to achieve the most accurate acoustic response ” both in studio and home-theater applications.

Rock-Solid Bass Performance
Bass you can feel takes some heavy-duty power and components. That's why the SBX10 carries a hefty 240-Watts of totally discrete Class A/B power for tons of headroom. The 10" driver features an oversized magnet 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 turbulence and improve low frequency efficiency. The fiberglass/paper composite driver provides exceptionally accurate bass response, resulting in a clean and refined low-frequency extension that minimizes listener fatigue.

No More Guesswork
A good monitoring system allows you to create material that translates well across a variety of playback environments. As such, it's important to know what your mixes will sound like both with and without the low-frequency extension a subwoofer provides. Fortunately, the SBX10 includes a subwoofer bypass function that completely removes the subwoofer amp, speaker, and crossover from the signal path. This sends the full-bandwidth program to your direct-field monitors. By plugging in the included footswitch, you can control this function dynamically as you're playing back your material ” even from across the room.

Optimizing Your Studio Monitor Setup and Placement

Why would anyone need directions for setting up reference monitors? Just put them on your desk, and you're done, right? Well, it turns out that reference monitors are actually one of the most important and influential elements of your studio, and can really make or break the performance of your whole setup.

Overkill (with the AV40's), which is fine.

By Rayne

from NC

Comments about M-Audio SBX10 Active Subwoofer:

I'm using this subwoofer currently with the M-Audio AV40's. I wrote "overkill" because it is made to go with more powerful powered monitors, but I keep it at a low volume to match them. I love having the headroom, since the amp is hardly having to work, so there is no chance of distortion or speaker anomalies. The build quality is amazing. The size and weight will probably surprise you. This sub is a fairly good size. I think it is a very accurate representation of the source, and so far has been a good combination with the AV40's. If you want good accuracy, you have it....if you want overpowering thump, room rattling rumble, (dance, dj) etc.., you can easily get that also. Having the footswitch is a great feature, so I can listen solely to the monitors without any crossover. You can also use the unbalanced rca inputs for your PC, and keep both audio interface and PC connected at the same time. I'll be able to use this subwoofer in the future when I can afford higher-end and/or more powerful monitors. Also, you can easily practice bass, or audition midi/sampled basses at high volumes with no distortion as needed. I did a lot of research on these, and there are a few competitors, (and hardly any solid reviews at the time on the SBX10 sub at the time), but the specs were much better than the competitors in this price range. I realize now after using them, that I made the best decision. Just set your crossover and volume properly, position your sub properly, position your monitors at the proper height, width, distance (very important!..I purchased 10 inch desktop stand), and you'll be ready to roll.


Sounds Good

Comments about M-Audio SBX10 Active Subwoofer:

Everything got shipped to me fine. Hooked up the sub and it sounds great! That being said, I don't have a ton of experience with different sub's to know which sounds best. If you want bass, it produces bass. All at a pretty good price compared to other options. One negative.. This sub comes with a pedal to turn the bass off and just hear the music through your monitors. Well, this pedal worked fine the first day and has not worked since. Been about two weeks.. I ordered this off of the internet, so this should be fun to deal with. At least the speaker works fine!
