Seas MCA12RC H1304-08 Paper Cone Midrange

Manually coated paper cone and mechanically matching natural rubber surround result in an unusually smooth midrange response.

1” high temperature voice coil is wound on an aluminium voice coil former to ensure a very high power handling capacity.

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.
