18LW2400

The 18LW2400 is a high-performance 18-inch extended low-frequency loudspeaker, engineered for high-SPL subwoofer applications in reflex, bandpass, or horn-loaded enclosures. Building on the success of the industry-standard 18LW1400, the 18LW2400 delivers higher maximum SPL, increased program power handling, and reduced power compression, making it ideal for demanding professional sound reinforcement systems.

Designed for optimal performance with amplifiers capable of delivering 2400 W program power without clipping, the transducer features a large-displacement suspension system, a fiberglass-reinforced straight-ribbed cone, and Eighteen Sound’s proprietary Double Silicon Spider (DSS) technology. Together, these elements ensure ultra-linear piston motion and precise mechanical control across the entire operating range.

A 100 mm (4-inch) inside–outside copper voice coil, based on Interleaved Sandwich Voice Coil (ISV) technology, provides exceptional thermal stability and long-term durability. Power handling is further enhanced through advanced voice-coil ventilation technology derived from the flagship 9000 Series neodymium transducers. A low-density air diffractor integrated into the backplate acts as an efficient cooling system, significantly reducing power compression.

​

As a result, the 18LW2400 achieves nearly 1 dB lower full-power compression compared to the 18LW1400, along with an increased 2400 W program power rating. Sound quality is further refined through Double Demodulating Rings (DDR) embedded in the pole piece, reducing harmonic and intermodulation distortion while improving transient response.

​

Optimized magnetic structure design using advanced FEA CAD simulations results in a 10% reduction in overall weight without compromising performance. Built for reliability in challenging environments, the 18LW2400 features a specially treated cone with enhanced pulp strength and water-repellent properties, along with corrosion-resistant coatings on the top and back plates—ensuring consistent performance even under harsh weather conditions.
