Seas Lotus Reference RW220 - L0022-04S

Beschreibung

Restart your audio experience with the Lotus Reference RW220 - L0022-04S by Seas, an 8" (20cm) woofer tuned for use in cars. As an 8" cone driver, this speaker offers high power handling, gold-plated connectors and exceptional bass precision thanks to its sturdy aluminum membrane. The product is characterized by its long high-temperature voice coil on an aluminum 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 extreme coil deflections and heavy copper rings to reduce distortion, this model paves the way for an optimal listening experience. Trust in Masori's quality and let us convince you.

• High resilience and gold-plated connectors characterize the  Lotus Reference  RW220 - L0022-04S.
• 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 rigid but lightweight aluminum diaphragm ensures tremendous bass precision.
• The very long high-temperature voice coil, which is wound on an aluminum voice coil former, offers high power handling.
• 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 the pole piece, and increases power handling.
• The magnet system is equipped with a compressed back plate that creates space for extreme coil deflections.
• Heavy copper rings mounted above and below the T-shaped pole piece reduce non-linear and modulation-related distortion and increase overload margin. Gold-plated terminals mounted on a glass-fiber reinforced plate reduce contact resistance and improve reliability.
