Description

18 Sound 6ND430 – High-Efficiency, Compact LF Driver with Neodymium Power

The 18 Sound 6ND430 is a premium 6.5-inch low-frequency driver engineered for high-output performance, clarity, and durability in demanding professional audio environments. Manufactured in Italy by 18 Sound, the 6ND430 combines the benefits of neodymium magnetic technology with precision transducer engineering, delivering excellent efficiency, low power compression, and fast transient response in a lightweight, compact design.

Whether integrated into a two-way system, compact line array, or professional monitor, the 6ND430 provides full-bodied mid-bass and detailed low-frequency reproduction in applications where performance, portability, and reliability are non-negotiable.

Designed for Speed, Accuracy, and Definition

At the heart of the 6ND430 is a 44 mm (1.75-inch) aluminum edge-wound voice coil, wound on a high-temperature fiberglass former. This configuration provides a lightweight yet robust motor structure capable of handling high current while maintaining exceptional control over diaphragm motion. As a result, the 6ND430 reproduces low frequencies with tight definition and delivers midrange presence that enhances speech intelligibility and musical detail.

With a usable frequency response from 63 Hz to 5.5 kHz, the 6ND430 is tailored for mid-bass reinforcement and versatile enough to perform as a dedicated low-frequency driver or as a mid-bass component in a multi-way system.

Advanced Motor Design for Low Distortion

One of the key innovations in the 6ND430 is its optimized neodymium magnet assembly, which delivers a high magnetic flux density in a compact footprint. The driver features an integrated aluminum demodulation ring, which significantly reduces harmonic and intermodulation distortion by stabilizing inductance over the driver’s working range. This contributes to a cleaner, more linear sound with better detail and less coloration.

In addition, the driver’s vented voice coil gap and ventilated back plate minimize heat build-up, reducing power compression and maintaining consistent output even during prolonged operation at high SPLs. These features make the 6ND430 particularly suitable for demanding touring applications, active speaker designs, and installations that require thermal efficiency and tonal stability.

Rugged, Lightweight Construction

Weighing in at just 1.25 kg, the 6ND430 is built for portability without sacrificing durability. Its reinforced pressed steel basket provides rigidity and resonance control, while the treated cellulose cone and double half-roll polycotton suspension offer both moisture resistance and mechanical precision.

The progressive spider design enhances cone control at higher excursion levels, improving performance consistency and reducing distortion under heavy use. This structural integrity ensures the driver remains stable and performs at its best even in high-vibration environments, such as mobile PA systems or stage monitors.

Ideal for Compact High-Performance Systems

The 6ND430 excels in speaker designs where weight, size, and output must be balanced. Thanks to its 92.5 dB sensitivity (1W/1m) and 200W AES power handling, the driver can produce impressive output from smaller enclosures without compromising sound quality. It is ideal for high-output mid-bass sections in line arrays, compact PA systems, and front fills, offering full-bodied response and seamless integration with compression drivers and subwoofers.

Its wide frequency range and low distortion profile also make it suitable for use in audiophile-grade monitoring and stage systems requiring articulate, musical low-frequency reproduction.
