Topping the improvements list are the 8" curved Kevlar low-frequency drivers-a technology usually reserved for monitors bearing a higher price tag. Of course, they’re coupled with the time-proven high-temperature voice coils and damped rubber surrounds for durability and fidelity. Magnetically shielded 1" natural silk domes give the BX8s a high-end that’s both clear and easy on the ears. Custom-tuned crossovers distribute 130 Watts of bi-amplified power for optimal frequency handling by each driver. Hear for yourself why Studiophiles have become "standard issue" reference monitors.Main Features:

- 130 Watts of bi-amped power
- 8" Kevlar low-frequency drivers
- 1" natural silk high-frequency drivers
- XLR balanced and 1/4" balanced/unbalanced inputs
Kevlar LF drivers
To insure a lifetime of service, M-Audio constructed the BX8a's 8" low-frequency driver from woven Kevlar-the same material bulletproof vests are made from. (Kevlar is typically reserved for more expensive monitors.) Their engineers also created a curved conical design that improves room dispersion. High-damping rubber surrounds insure that the cone reaches exactly its optimal excursion for accurate reproduction. And the high-temperature voice coils guarantee that your monitors will deliver full performance no matter how many hours you use them.
Silk-dome HF drivers with FerroFlowTM
The high-frequency domes are made from natural silk to counter the ringing that is inherent in the stiffer metallic materials common to other monitors. M-Audio's FerroFlowTM technology uses ferrofluid liquid cooling to dissipate heat for maximum efficiency and extended usage.
Bi-amped efficiency
Active (powered) monitors allow designers to optimize amplification for other components such as speakers and cabinets. And by using two separate power amps and a finely tuned crossover, the BX8a's bi-amped design insures that both the high- and low-frequency drivers are each sent only the frequencies they reproduce most efficiently.
Rear-ported cabinet design
The BX8a's cabinet is integrally designed with its other components for optimal performance-right down to rounded corners for reduced edge diffraction and superior imaging. Custom rear-port design eliminates the turbulence and resulting distortion caused when front ports project low frequency waves in the same path as the speakers' direct signal.
