The 1501AL and 476Be are both designed to be absolute-minimum-distortion
drive units. Although they are capable of tremendous acoustic output, they are
designed to be completely linear in every way, up to a reasonable drive level.
This enables the system to sound the same, regardless of playback level.

The 1501AL Low-Frequency Driver
The 1501AL low-frequency driver is very similar to the 1500AL used in the
K2 S9800 system. It incorporates a new high-impedance voice coil to allow a
pair of woofers to be used while still maintaining an 8-ohm system impedance.
The voice-coil length has been increased to 1-3/16 inch (30.5mm) – from 13/16
inch (20.3mm) – and its milling width has been reduced slightly. This was done
to allow greater clearance from the outer diameter of the coil to the laminated
top plate and to provide a larger area of coil surface for heat dissipation. These
coil improvements allow the 1501AL to handle up to 25 percent more power
than the 1500AL.
