This high-excursion driver is the ideal choice for professional touring rigs, fixed installations in nightclubs and concert halls, and high-end home cinema setups where uncompromising low-end performance is essential. Its robust construction and carefully optimised parameters make it equally suited for both vented and horn-loaded enclosures, providing flexibility for system designers and audio enthusiasts alike.

At the heart of this subwoofer lies a remarkable combination of technical features that ensure powerful, controlled bass reproduction. With a 98 dB sensitivity (1m/2.83V) and a maximum linear excursion (Xmax) of 13 mm, the 21QLEX1600Fe delivers impressive output with minimal distortion. The total Q factor (Qts) of 0.28, derived from a low electrical Q (Qes) of 0.3 and a mechanical Q (Qms) of 4.5, indicates excellent damping and transient response. The substantial displacement volume (Vd) of 2254 cm³, coupled with a 5.4 ohm DC resistance (Re) and a voice coil inductance (Le) of 4 mH, ensures efficient power handling and deep, articulate low frequencies. The 533.4 mm nominal diameter driver features a 492 mm cutout diameter and a mounting depth of 266 mm, requiring a 522.5 mm bolt circle for secure installation. This subwoofer is the definitive choice for those seeking uncompromising low-end authority.
