Product Description
This 12 inch 4 ohm member of the XXLS product family has all the design features suitable for a high
performance, high excursion subwoofer driver. The motor features a double ferrite magnet motor,
supporting high excursion, and aluminium shorting rings and pole extenders, lowering and linearizing
the inductance of the overhung voice coil. The Aluminium cone is vented under the dust cap, to reduce
air compression. The suspension system features a low-creep rubber surround, and a nomex spider,
ensuring long-term reliability under high power conditions. The product also features a rigid cast
aluminium basket.
