M-Audio BX4 BT 4.5" Studio Monitors w/ Bluetooth (Pair)
Compact 4.5-Inch Monitoring with Bluetooth and Room-Tuning Controls
The M-Audio BX4 BT is a compact pair of multimedia reference monitors for music production, streaming, podcasting and everyday listening. Each speaker combines a 4.5" Black Kevlar low-frequency driver with a 1" natural silk dome tweeter, while the computer-optimised waveguide helps maintain precise stereo imaging. The system delivers 120W total peak output with a frequency response of 69 Hz–22 kHz.
Bluetooth lets you stream audio wirelessly from compatible devices, while wired sources can connect through stereo RCA, dual 6.35 mm (1/4") TRS or front 3.5 mm (1/8") AUX inputs. A front headphone output mutes the speakers for private listening.
High and Low EQ controls let you adjust the response for your room, while enhanced rear ports extend the low end. A Left/Right Active Speaker Position switch lets you choose which side carries the front volume control. Each speaker measures 156 × 175 × 225 mm (6.1" × 6.9" × 8.9").
At Riffs & Licks Music, we think this monitor pair is ideal for compact setups that need flexible wired connections, Bluetooth playback and useful room-adjustment controls.
