Professional Performance and Design

M-Audio’s BX4BT monitors produce 120 watts of professional sound inside a futuristic design that delivers pro-grade sound. The two-way design features an acoustically inert MDF cabinet with bass reflex that pushes low frequencies through modern black Kevlar drivers. Plus, enhanced rear ports and computer-optimized natural silk-dome tweeters deliver the full spectrum of frequencies needed for any type of media.

Front & Rear Panel I/O

The BX4BT monitors offer all the connections you need to playback audio from all your devices. The rear panel features 1/4", 1/8" and RCA inputs, while the front panel features 1/8" AUX input and a headphone connection that turns the speakers off for private listening. This feature is great for those late nights in the home office or mixing sessions where you don’t want to disturb anyone.

Speaker Placement Controls and EQ

The M-Audio BX4BT features a Left/Right Active Speaker Position switch, letting you choose which speaker is sounding from the left or right side. This is useful if you are left-handed and want the speaker with the front panel volume control on your left side, or vice versa. Also on the rear panel are High-EQ and Low-EQ controls to boost or cut the low end or add some shimmer to the highs.

MPC Beats DAW With Effects and Instruments

The M-Audio BX4BT comes bundled with MPC Beats, the powerful music-making and recording desktop software DAW for Mac and PC based on iconic MPC hardware. Featuring a full array of musical instrument plug-ins, effect plug-ins, and audio and drum samples, MPC Beats is the best way to start making great-sounding music quickly.
