Product details

SEAS Lotus RW220 – L0022-04S Woofer
 
 
8” cone driver with an extremely stiff and stable injection moulded metal basket to keep the critical components in perfect alignment. The stiff, yet light aluminum cone gives tremendous bass precision.

The very long high temperature voice coil wound on an aluminium voice coil former gives a high power handling capacity.

The phase plug reduces compression due to temperature variations in the voice coil, eliminates resonances that would occur in the volume between the dust cap and the pole piece and increases the power handling capacity.

The magnet system is equipped with a bumped back plate which makes room for extreme coil excursions.

Heavy copper rings mounted above and below the T-shaped pole piece reduce non linear and modulation distortion and increase overload margin. Gold plated terminals mounted on a glass fibre reinforced plate reduce contact resistance and improve reliability.
