12TBX100 specifications

B&C Speakers, a renowned manufacturer in the professional audio industry, has made a significant impact with its high-performance drivers. Among its standout offerings is the 12TBX100, a speaker driver that excels in various applications, particularly in the realm of live sound and professional audio installations.

At the heart of the 12TBX100 is a robust 12-inch woofer designed for high output and exceptional sound clarity. One of the defining features of this driver is its unique double spider suspension system. This technology not only enhances linearity but also provides greater cone movement control, resulting in reduced distortion and improved sound quality. The 12TBX100 has a power handling capacity of 800 watts AES, making it suitable for demanding environments where high levels of sound pressure are required.

Another notable characteristic of the 12TBX100 is its advanced voice coil assembly. Equipped with a 3-inch voice coil made from high-temperature materials, this driver ensures reliability and performance even during extended sessions of loud playback. The voice coil design is optimized for thermal dissipation, greatly reducing the risk of overheating and enhancing the lifespan of the driver.

The 12TBX100 features a high-efficiency neodymium magnet system, which contributes to its low weight and high power-to-weight ratio. This design choice is particularly beneficial for portable sound systems, allowing for easier transport without sacrificing performance. The neodymium magnet not only provides a powerful magnetic field but also helps maintain a compact overall driver size.

Sound quality is further ensured through a carefully engineered cone design. The cone is made from a proprietary blend of materials that strike an ideal balance between rigidity and flexibility. This ensures that the driver can produce deep, impactful bass, while still being able to articulate midrange frequencies with precision.

Finally, the 12TBX100 is designed with versatility in mind. It can be used in a variety of speaker enclosures and configurations, making it a favorite among sound engineers and system designers. Whether used in a subwoofer application or as part of a full-range speaker, the 12TBX100 consistently delivers outstanding audio performance.

In summary, the B&C Speakers 12TBX100 is a top-tier 12-inch driver that embodies the latest advancements in audio technology. Its combination of high power handling, thermal resilience, efficient magnet design, and superior sound quality makes it a preferred choice for professionals seeking reliability and performance in demanding audio applications.
