The L22RN4X/P is an 8” cone driver with a extremely stiff and stable
injection moulded metal basket to keep the critical components in perfect
alignment. Large windows in the basket both above and below the spider
reduce sound refl ection, air fl ow noise and cavity resonance to a minimum.
The extremely stiff aluminum 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. On the other hand,
the cone break up modes at higher frequencies call for special attention in
the crossover design work. A 4-layer, extremely long, high temperature voice
coil wound on an aluminum voice coil former gives a high power handling
capacity. The 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. The large magnet system provides reasonably high effi
ciency and low Q.
