4. Enclosure
Like the other components, the BX8a’s enclosure has an important role in shaping the overall sonic
response. In order to provide more stable performance, the BX8a’s enclosure employs a special high
acoustic efficiency MDF and unique interior reinforcement designed to absorb vibration and impact
generated under extreme conditions. The custom design on the front panel will aid in diffraction and will
benefit stereo imaging.
5. Network and Power Amplifiers
The active crossover network and power amplifiers for the BX8a are specially designed for its woofer
and tweeter. The network properly distributes low, mid, and high frequencies to the driver components in
order to reduce distortion and loss of sound, thus achieving a naturally balanced sound.
In order to generate powerful, ultra-crisp sound, there are two separate power amplifiers inside the BX8a
for driving the woofer and tweeter separately in a high-end bi-amp structure. The power delivered to the
woofer driver at a low-rated distortion is 70W, and 60W is also delivered to the tweeter.
