M-Audio BX4 BT Active Studio Monitor 2 pcs

M-Audio BX4 BT — Compact Bluetooth Studio Monitors with 120 W of Reference Sound

The M-Audio BX4 BT is a pair of 4.5-inch multimedia reference monitors that bring 120 W of clean, room-filling sound to small studios and home offices. A two-way design pairs a Black Kevlar low-frequency driver with a computer-optimized natural silk dome tweeter, reproducing the full audible spectrum with the imaging detail needed for mix decisions.

What Sets the BX4 BT Apart in the Compact Monitor Category

Black Kevlar cones and a computer-optimized tweeter waveguide deliver precise stereo imaging from a cabinet small enough to sit on any desk. Enhanced rear ports extend bass response down to 69 Hz, while a Left/right Active Speaker Position switch lets users place the volume knob on whichever side feels natural.

Driver Configuration and Amplification — Punch Beyond the Size

Each cabinet houses a 4.5" Black Kevlar woofer and a 1" silk dome tweeter, driven by a built-in amplifier delivering 120 W total peak power (2 x 25 W RMS). The Kevlar cone stays rigid under high excursion, keeping low-frequency transients articulate rather than muddy.

• LF Driver: 4.5" / 114 mm Black Kevlar cone — rigid material keeps bass tight
• HF Driver: 1" / 25 mm natural silk dome — smooth highs without harshness
• Output power reaches 120 W peak (2 x 25 W RMS) — headroom for near-field monitoring

Inputs, Bluetooth, and EQ — Plug In Anything, Tune the Room

Bluetooth wireless streaming, balanced 1/4" TRS, unbalanced RCA, and a front-panel 1/8" AUX input mean the BX4 BT accepts audio from interfaces, controllers, mixers, phones, and laptops. Rear-panel High-EQ and Low-EQ controls compensate for placement against walls or in corners.

• Wired Inputs: RCA stereo, 1/4" (6.35 mm) TRS, 1/8" (3.5 mm) AUX
• Bluetooth Range: up to 30.5 m (100 ft)
• Rear-panel High-EQ and Low-EQ controls tune response to match room acoustics

Cabinet Design and Physical Specs — Built for the Desktop

An acoustically-inert MDF cabinet with bass-reflex porting keeps resonance out of the mix, while the compact 156 x 175 x 225 mm footprint fits beside a laptop. At 4.46 kg per speaker, the BX4 BT stays planted on the desk.

• Cabinet: MDF with bass-reflex and enhanced rear ports — extends low-frequency response to 69 Hz
• Dimensions (per speaker): 156 x 175 x 225 mm
• Each speaker weighs 4.46 kg — stable platform that resists vibration

Who Should Choose the M-Audio BX4 BT

Built for bedroom producers, podcasters, and content creators, the M-Audio BX4 BT is the right choice for anyone needing accurate near-field monitoring plus Bluetooth convenience. Home users will appreciate the front-panel headphone output that mutes the speakers for late-night sessions. DJs benefit from RCA inputs that accept controller and mixer outputs directly.
