Description

18 Sound 18LW1400 – High-Performance 18-Inch Subwoofer Driver for Demanding Low-Frequency Applications

The 18 Sound 18LW1400 is a world-class 18-inch subwoofer driver engineered for superior low-frequency reproduction in the most demanding professional sound reinforcement systems. Designed and manufactured in Italy by 18 Sound, the 18LW1400 is the result of advanced transducer design, premium materials, and meticulous quality control—making it one of the most respected high-power subwoofer drivers on the market today.

Optimized for both bass reflex and horn-loaded enclosures, the 18LW1400 delivers massive low-frequency impact, deep extension, and exceptional power handling. It’s the ideal choice for large PA systems, touring subwoofers, dance clubs, outdoor concerts, and any application that demands uncompromised bass performance.


Massive Output and Clean Low-End Response

At the heart of the 18LW1400 is an 18-inch cone with a 100 mm (4-inch) inside/outside copper voice coil, built to handle extreme power and ensure precise cone control under high excursion conditions. With a continuous program power handling of 1400W and an AES power rating of 1000W, this subwoofer is built for loud, extended performance without distortion or failure.

The 18LW1400 operates effectively in a frequency range of 28 Hz to 2.5 kHz, offering a solid, deep bass foundation and smooth upper bass response. Whether used in large-format subwoofer arrays or single-cabinet systems, it delivers punch, authority, and remarkable clarity—without sacrificing power or tone.


Engineered for Durability and Thermal Efficiency

The 18LW1400 is built for continuous, heavy-duty operation. The voice coil is wound on a fiberglass former, which is resistant to temperature-induced deformation, while the vented voice coil gap and large ferrite magnet help to reduce power compression by enhancing airflow and cooling efficiency.

The driver also features a dual silicon spider and reinforced suspension system that ensure controlled excursion and consistent linearity, even at extreme SPL levels. These innovations allow the 18LW1400 to maintain sonic integrity during high-demand usage, making it a trusted choice for professionals around the globe.


Designed for Performance and Flexibility

Whether you are building folded horns, bandpass enclosures, or vented boxes, the 18LW1400 offers design flexibility with its optimal Thiele/Small parameters. It delivers peak performance in enclosures ranging from 140 to 250 liters, making it easy to integrate into new or existing cabinet designs.

This versatility makes the 18LW1400 perfect for use in front-of-house systems, touring rigs, cinema subwoofers, and installations requiring dependable and extended low-frequency response.
