M-Audio announced the new Studiophile BX5 reference monitors at this year's Winter NAMM show. The BX5s offer 76 watts of bi-amped near-field technology at a fraction of the cost of other monitors their size.

Integral to the design of the BX5s is the concept that monitors should be able to adapt to changes in placement or work environment. Since a monitor's bass response can change depending upon proximity to walls, the BX5s' Acoustic Space control section allows users to optimize the monitors' performance--no matter whether they need to go on stands, on a bookshelf or in the corners of a room. Users can also adjust the high-frequency response to compensate for reflective surfaces like glass. The Presence control provides an automatic mid-range boost for added flexibility. The BX5s even include variable low-frequency roll-off to optimize response at crossover points when adding a subwoofer like the Studiophile SP-8S.

The key to the BX5s' sound is the synergistic active design and integration of all elements, rather than systems comprised of separate components. The BX5s' bi-amped design enhances fidelity by sending only the optimal frequencies to the high and low drivers. The integral crossover network and power amplifiers deliver flat frequency response, smooth transition in the crossover region, minimal distortion and maximized power handling.

The 1-inch natural silk high-frequency drivers employ a flush design and electronic time alignment with the low-frequency driver, resulting in controlled dispersion for superior three-dimensional imaging. The high-frequency drivers also employ ferrofluid cooling and internal damping to minimize resonance. The 5.25-inch low-frequency drivers feature curved mineral-filled polypropylene cones with high-temperature tolerant voice coils to insure longevity and damped rubber surrounds to control unwanted resonance. All drivers are magnetically shielded for desktop music production. The tooled rear Sub-Frequency Ports reduce low-frequency turbulence and optimize driver excursion for amazing bass despite the BX5s' small footprint.
