18NW100 specifications

B&C Speakers is renowned for its high-quality audio drivers and transducers, and the 18NW100 is a standout in their range. This 18-inch neodymium subwoofer is designed for professional audio applications, making it ideal for portable and installed sound systems, bass reflex enclosures, and more.

One of the main features of the 18NW100 is its neodymium magnet structure, which offers significant weight savings without compromising on performance. Weighing approximately 17 kg, this subwoofer is considerably lighter than traditional ferrite magnet models, making it easier to transport and install while maintaining high power handling capabilities.

The 18NW100 boasts an impressive power handling capacity of 1000 watts (continuous) and 2000 watts (peak), enabling it to handle the most demanding audio environments. This power handling is complemented by a sensitivity rating of 95 dB, allowing it to deliver powerful and punchy bass response even at lower power levels. Its frequency response spans from 30 Hz to 1 kHz, ensuring that it can reproduce the lower end of the spectrum with clarity and depth, suitable for everything from music to sound effects in live performances.

The design of the 18NW100 incorporates advanced technologies to enhance performance. The cone is constructed from a mix of paper and other composite materials, allowing for exceptional stiffness and damping characteristics while minimizing distortion. The voice coil is centered in a high-temperature fiberglass former, which improves thermal stability and allows for greater excursion, resulting in a more dynamic range.

Additionally, the ribbed surround plays a vital role in ensuring durability and flexibility, facilitating wider cone movement while reducing the risk of damage due to over-excursion. The speaker features a dual spider design, providing added stability during operation and ensuring consistent performance even under challenging conditions. Its vented pole piece also contributes to effective cooling, preventing overheating during prolonged use.

Overall, the B&C Speakers 18NW100 embodies a perfect combination of lightweight design, robust power handling, and exceptional sound quality. Its innovative technologies and meticulous construction make it a top choice for audio professionals looking for a reliable and high-performing subwoofer that can deliver deep, impactful bass across a wide variety of applications.
