SEAS Excel W18E-001/TV (E0027) Shielded 7" Magnesium Cone Woofer
This Seas Excel shielded magnet 7" woofer features a light, yet stiff magnesium cone for bass precision and midrange detail. The cone is attached to the magnesium cast frame by a natural rubber surround that shows no sign of midrange (edge) resonance. Heavy copper coils mounted above and below the T-shaped pole piece reduce non linear and intermodulation distortion. The raised spider keeps the voice coil from bottoming out and also reduces noise caused by mechanical distortion. This speaker has been optimized for use in home theater systems or used near CRTs.
