Selecting LARGE for the multi-channel speaker option will give
a full range output. Selecting SMALL for the multi-channel
speaker option will activate a high pass filter whose crossover is
dependent on the sub-woofer low pass frequency. For example,
if the subwoofer low pass filter is set to 80Hz, then the high
pass SMALL speaker crossover will be set to 90Hz.
