Classical handcoated paper cone and matching natural rubber surround produce a
well behaved roll off characteristic and reduce potential resonance problems.
2” high temperature voice coil with black anodized aluminium coil former gives
high power handling and reduced power compression.
Large magnet system gives good sensitivity and transient response.
Bumped backplate in the magnet system allows maximum utilization of the
long voice coil without mechanical limitation.
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.
