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 Deluxe 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
Deluxe 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.
Front and Rear Panel Features
Rear Panel Features
1. XLR INPUT: This jack accepts XLR input connections with either balanced or unbalanced
wiring. The input wiring of an XLR connector should be as follows:
< XLR PIN 1 . . . . . . . . signal ground (shield)
< XLR PIN 2 . . . . . . . . signal positive (+)
< XLR PIN 3 . . . . . . . . signal negative (–)
2. TRS INPUT: This jack accepts 1/4” connections with either balanced or unbalanced wiring.
For balanced wiring, a three-conductor TRS plug is necessary. The input wiring of a TRS
connector should be as follows:
< TRS TIP . . . . . . . . . . signal positive (+)
< TRS RING . . . . . . . . signal negative (–)
