Seas W18EX-RA H1400-04 Woofer is a Seas Excel 6.5" 4 Ohm Woofer especially made for a major OEM manufacturer with a precision cast magnesium cone and natural rubber surround.
The large magnet system enables extreme coil excursions, and heavy copper rings mounted above and below the T-shaped pole piece reduce non linear and modulation distortion and increase overload margin.
A copper phase plug reduces compression due to temperature variations in the voice coil, increases long term power handling capacity and eliminates resonances in the cavity inside the voice coil former.
Gold plated terminals mounted on a glass fibre reinforced plate to reduce contact resistance and improve reliability.
An extremely stiff and stable injection moulded metal basket keeps the critical components in perfect alignment, and large windows in the basket both above and below the spider reduce sound reflection, air flow noise and cavity resonance to a minimum.
