M-Audio BX5a Deluxe Active Monitors

The Studiophile BX5a Deluxe monitors update the best-selling M-Audio systems with a variety of enhancements. New waveguides deliver excellent imaging. Custom amplifier tuning enhances the integration between the high and low frequencies, delivering refined spectral balance and a smoother response. A new low-frequency transducer adds extra definition to the bass response.

The Studiophile Deluxe monitors feature 5 in. Kevlar low-frequency driver cones, respectively. Kevlar's high mechanical and thermal resilience makes it ideal for speaker cones. These low-frequency drivers also employ a curved cone design, high-temperature voice coils and damped rubber surrounds that provide percussive musical bass. The Deluxe monitors also feature new waveguide-loaded high-frequency drivers with natural silk domes to deliver pristine top end that is gentle on the ears.

Kevlar drivers
M-Audio's new monitor employs Kevlar for low-frequency driver construction. The same material used in bulletproof vests, Kevlar's high resilience makes it ideal for use in speaker cones-although it is typically reserved for monitors with higher price tags. Needless to say, Kevlar represents a significant improvement over the polypropylene and paper used in most monitors for this price.

Magnetically shielded for desktop use
Unchecked, the electromagnetic waves emanating from your speakers can wreak havoc with your computer's video monitor or a nearby TV. The BX5a is magnetically shielded so that all of your electronic equipment can coexist on your desktop without interference.

Bi-amplified efficiency
Active monitors have a distinct advantage over unpowered monitors, in that the built-in power amps are designed specifically to work with the drivers and crossovers in a tuned system. Bi-amplification further refines the concept by dedicating separate power amps to the highs and lows. Combined with a finely tuned crossover, this design insures that both the high- and low-frequency drivers are asked to deliver only the frequencies they are more efficient at reproducing.
