M-Audio is now shipping the Studiophile BX5a, an updated version of the company’s BX5 near-field reference monitor. The upgrade centers on improved driver materials and a new industrial design.
The BX5a monitors’ 5-inch low-frequency driver cone is crafted from Kevlar, in contrast to the polypropylene used in the original BX5. Kevlar is the same material used in bulletproof vests, and its high resilience makes it ideal for use in speaker cones—although it is typically reserved for monitors with higher price tags than the BX5a. These low-frequency drivers also employ a curved cone design, with high-temperature voice coils, damped rubber surrounds, and natural silk domes on 1-inch high-frequency drivers.
The integral design of the BX5a cabinet and circuitry yields an increase in bass response over the original BX5. Crossovers combine with 70 watts of bi-amped power (40 watts for low frequencies, 30 watts for high frequencies), while magnetic shielding makes them suitable for desktop use. The units also have a power indicator and volume control.
Specifications for the BX5a include 56Hz-22kHz frequency response, 3kHz crossover frequency, greater than 100dB dynamic range (typical, A-weighted), input impedance of 20k ohms balanced (10k ohms unbalanced) and input sensitivity of 90dBA SPL at 1 meter with 85 mV pink noise input (volume control at maximum). The BX5a is factory programmed for either 115V ~50/60Hz or 230V~50/60Hz. Protective features include RF interference, output current limiting, over temperature, turn-on/off transient, subsonic filter, and external mains fuse. Dimensions are 9.85 in. (h) x 6.54 in. (w) x 7.88 in. (d); weight is 11 lbs/unit. MSRP: $399.95 per pair USD.
