Seas Lotus Reference RW220 - L0022-04S

Description

Reboot your audio experience with the Lotus Reference RW220 - L0022-04S from Seas, an 8" (20cm) bass-midrange speaker tuned for in-car use. As an 8" cone driver, this speaker offers high power handling, gold-plated connections and exceptional bass precision thanks to its stable aluminum cone. The product is characterized by its long high-temperature voice coil on an aluminium carrier, which enables high power handling. In addition, it uses a phase plug to increase power handling and eliminate resonances. With a magnet system that allows for extreme coil excursion and heavy copper rings to reduce distortion, this model paves the way for an optimal listening experience. Trust Masori's quality and let us convince you.

• The Lotus Reference RW220 - L0022-04S is characterized by its high load capacity and gold-plated connections.
• It is an 8" cone driver with an extremely rigid and stable injection-molded metal basket that keeps the critical components in perfect alignment. The stiff but lightweight aluminum cone ensures enormous bass precision.
• The very long high-temperature voice coil, which is wound on an aluminum voice coil former, offers a high load capacity.
• The phase plug reduces compression due to temperature fluctuations in the voice coil, eliminates resonances that would occur in the volume between the dust cap and pole core, and increases the power handling capacity.
• The magnet system is equipped with a compressed back plate, which creates space for extreme coil deflections.
• Heavy copper rings mounted above and below the T-shaped pole piece reduce non-linear and modulation distortion and increase the overload margin. Gold-plated terminals mounted on a fiberglass-reinforced plate reduce contact resistance and improve reliability.
