Seas Prestige CA12RCY - H1152-08 4.5" Coated Paper Cone Woofer

 

Natural rubber surround and handcoated paper cone with coated fabric dust cap, reduce resonances and distortion. Large magnet system and a symmetrical driving force accomplished through a special coil winding technique for the voice coil gives an excellent linearity. Very large magnet system provides a reasonable efficiency and a low Q.

 

Extremely stiff and stable injection molded 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.
