B&C 400 Watt 8 Ohm 10" Speaker

Overview

Introducing the B&C 400 Watt 8 Ohm 10" Speaker, a pinnacle of audio engineering designed for audiophiles and professionals alike. With a continuous program power capacity of 400 Watts, this speaker is ready to handle even the most demanding audio scenarios. The 64 mm (2.5 in) aluminum voice coil ensures clarity and responsiveness, working within a broad frequency range of 60 - 4000 Hz. With a 98.5 dB sensitivity, every note comes through with precision and volume. At the core of its impressive features is a neodymium magnet, delivering a lightweight yet powerful motor assembly.

The speaker’s specifications are equally impressive. It has a nominal diameter of 250 mm (10.0 in) and a minimum impedance of 6.2 Ω. With its exponential cone shape and double roll surround design, this speaker produces uncompromised sound quality. No need to worry about mounting—its overall diameter is 261 mm (10.3 in), and its depth is just 122 mm (4.8 in). It fits snugly in a recommended enclosure of 26.0 dm3 (0.92 ft3) and is optimized for a tuning frequency of 67 Hz.

Beyond its technical prowess, this speaker is also easy to install. With a net weight of 1.95 kg (4.3 lb) and shipping weight of 2.55 kg (5.62 lb), it won’t weigh down your audio setup. Whether you're a musician, a sound engineer, or an audiophile, the B&C 400 Watt 8 Ohm 10" Speaker is a robust and reliable choice for high-quality sound reproduction.
