M-Audio BX4

Design Excellence: Compact yet Stylish

The M-Audio BX4 boasts a design that’s both visually appealing and space efficient. With dimensions of 156 x 175 x 225mm, its compact form factor doesn’t sacrifice style for functionality. The 4.5” Kevlar LF driver, coupled with a 1” silk dome HF, presents a sleek, modern aesthetic that seamlessly fits into any studio setup.

Active and Passive Configuration: A Space-Saving Marvel

Powered by 2 x 25 Watt RMS, these monitors feature an active plus passive configuration. The audio inputs and mains power are channeled into the active speaker, while the second passive speaker connects through a 3.5mm TS interconnect cable. This smart setup minimizes clutter and simplifies cable management for a tidy workspace.

Input Versatility: Convenience Redefined

Equipped with both balanced (TRS jacks) and unbalanced inputs (RCAs), the M-Audio BX4 is incredibly versatile. Setting up these monitors is a breeze, and the option to specify left/right on the active monitor allows for flexible positioning based on individual preferences.

Performance Unveiled: Finding the Sweet Spot

The rear-ported design of the M-Audio BX4 necessitates some space behind them for optimal performance. However, the high and low-frequency EQ (+/-6dB for each) offers ample room for customization. The front panel hosts controls for global level, headphone output, and an auxiliary input, ensuring ease of access and functionality.

Sonic Brilliance: Quality Meets Flexibility

The BX4’s rear-ported design effectively extends bass delivery, while the adjustable bass EQ enables further customization. The sweet-sounding high-frequency EQ complements various room acoustics, enhancing the overall audio experience. Despite slight sweetening in sound, the stereo imaging remains impressive, courtesy of the tweeter waveguide that creates a broad sweet spot.

Verdict: Compact Versatility at a Value

While the M-Audio BX4 deliver a larger scale compared to the BX3s, both sizes exhibit surprising strength and volume. Aimed at a broader market than their larger counterparts, these monitors offer flexibility and decent sound quality. Whether working on a budget or seeking a compact yet capable monitoring setup for production, podcasting, or multimedia needs, the BX monitors deliver commendable value.

The Web’s Voice: A Niche of Excellence

The BX4s have garnered praise for their suitability in small rooms, catering to DJing, podcasting, live streaming, and even beat making. While not ideal for exhaustive music production due to their size limitations and slight discrepancies in accuracy compared to higher-priced speakers, they serve as an excellent secondary pair for reference in larger studios.

Specifications: Unveiling the Tech Marvel

The BX4 specifications speak volumes: 4.5” Kevlar LF, 1” silk dome HF, and 120-Watt total peak power. With a frequency response of 69Hz – 22kHz, these monitors pack a punch within their compact dimensions of 156 x 175 x 225mm.

Final Verdict: The Compact Powerhouse

In essence, M-Audio’s BX4 monitors redefine the appeal of the BX range. Their compact build, coupled with commendable performance, solidifies their position in the market, all at an incredible price point.
