Beyma 21LEX1600Nd Subwoofer

The Beyma 21LEX1600Nd Subwoofer represents a pinnacle of low-frequency engineering, designed to deliver profound, authoritative bass with uncompromising precision. As a 21-inch driver from a brand renowned for professional-grade audio components, this subwoofer is purpose-built for high-output sound reinforcement systems, large-scale home theatres, and custom car audio installations where deep, clean low-end extension is paramount. Its robust construction and advanced motor system make it equally suited for live sound venues, nightclubs, and studio monitoring applications that demand both power and accuracy.

At the heart of this subwoofer lies a formidable neodymium magnet structure, which enables exceptional motor force while minimising weight and thermal compression. The driver achieves a linear excursion of 14 mm, with a total displacement volume of 2428 cm³, ensuring it can move substantial air for visceral, room-filling bass. Sensitivity is rated at an impressive 98 dB SPL at 1 metre with 2.83V input, while the total Q factor of 0.29 indicates a well-damped response ideal for sealed or vented enclosures. The 4.7 mH voice coil inductance and 5.4 ohm DC resistance further contribute to controlled, efficient operation. With a mechanical Q of 8.6 and an electromagnetic Q of 0.3, this subwoofer offers tight, articulate low-frequency reproduction that remains composed even at high drive levels.

Engineered for durability and performance, the Beyma 21LEX1600Nd features a 533.4 mm nominal diameter with a cut-out diameter of 492 mm and a bolt circle of 522.5 mm, ensuring straightforward integration into existing systems. Its 268 mm depth accommodates the powerful neodymium motor assembly. Whether for professional touring systems or discerning audiophile setups, this subwoofer delivers the low-end authority and clarity that define reference-grade sound reproduction.
