Subwoofers For Modern Demands
The L22ROY2 is a high-fidelity woofer intended for multi-way systems, closed box and transmission line designs. With an extremely stiff aluminium cone, it provides a tremendous bass precision.

The Power Within
A 2″ / 50.8 mm diameter high power titanium voice coil former with a long copper winding for excellent force transfer and transient sound reproduction. A large rubber surround together with a textile spider allow for the outstanding linear excursion of the coil while keeping it well centered at high power. These characteristics result in a very low mechanical damping for better clarity bringing up the micro details in music.

FEA Optimised Motor
These subwoofers feature a large FEA optimised magnet system with a very big center hole through the pole piece and precisely fitted copper parts for excellent linearity, high power handling and low distortion. Below the T-shaped pole piece there is a heavy copper ring and on top, a thick aluminium ring; they both help to reduce nonlinear and modulation distortion. The stiff and stable injection moulded metal basket keeps the critical components in perfect alignment. Large windows in the basket both above and below the spider reduce sound reflection, air flow noise and cavity resonance.
