15NW76 specifications

B&C Speakers is renowned for designing and manufacturing high-quality audio components, and the 15NW76 is no exception. This professional-grade 15-inch woofer is specifically engineered for high-performance applications, making it a preferred choice among audiophiles and sound reinforcement professionals.

One of the standout features of the 15NW76 is its impressive power handling capacity. With a continuous power handling of 700 watts and a peak power handling of 2800 watts, this woofer can deliver robust sound even at high volumes. This capability ensures that it can endure rigorous use in live sound environments without compromising audio quality.

The 15NW76 utilizes a high-efficiency neodymium magnet structure, which significantly reduces weight without sacrificing performance. This innovative design not only contributes to the speaker’s lightweight profile but also enhances its overall sensitivity, allowing it to produce louder volumes with less input power. This efficiency is crucial for portable PA systems and other applications where weight and power usage are critical.

Another important characteristic of the 15NW76 is its optimized suspension system. The speaker features a well-designed spider and a linear voice coil that allow for remarkable excursion. This enables the woofer to reproduce deep bass frequencies with precision and minimal distortion. The extended frequency response, typically ranging from 40 Hz to 2 kHz, ensures that it can handle both low-end thump and clear mid-range sounds effectively.

The cone is crafted from a durable yet flexible composite material, which contributes to the woofer's robust performance while enhancing its durability. This construction makes the 15NW76 suitable for a variety of demanding environments, from touring sound systems to fixed installations in clubs and theaters.

Additionally, the woofer's voice coil is wound on a high-temperature form, enabling it to withstand extreme conditions during extensive use. This design choice limits power compression, ensuring consistent sound quality over long periods.

In summary, the B&C Speakers 15NW76 is a high-quality woofer that excels in both performance and durability. Its combination of high power handling, lightweight neodymium design, effective suspension system, and robust materials make it a preferred choice for professionals seeking reliable sound reinforcement solutions. Whether used in live performances or installed in sound systems, the 15NW76 delivers exceptional audio fidelity and reliability.
