Classical manually coated paper cone and matching natural rubber surround produce a smooth response and reduce potential resonance problems.

Four layer voice coil provides a well behaved roll off characteristic.

Large magnet system gives good sensitivity and transient response.

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.
