Extremely stiff aluminium cone gives tremendous bass precision.
The cone and the low loss rubber surround show no sign of the familiar cone
edge resonance and distortion associated with soft cones.

2” diameter 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.

Phase plug reduces compression due to temperature variations in the voice coil,
eliminates resonances that would occur in the volume between the dust cap and the
pole piece and increases the 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 reflection, air flow noise and cavity resonance to a minimum.
