SEAS Excel W18E-001 (E0018) 7" Magnesium Cone Woofer

• Magnet system with bumped back plate 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.
• Extremely 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 reflexion, air flow noise and cavity resonance to a
• minimum.
• Gold plated terminals mounted on a glassfibre reinforced plate to reduce contact resistance and improve reliability.
