	• The crossover frequency may be set too low; try setting it higher to match the characteristics of
	your other speakers (see Speaker Setting on page 85).
	• If there is very little low frequency information in the source material, change your speaker settings
	to Front: SMALL / Subwoofer: YES, or Front: LARGE / Subwoofer: PLUS (see Speaker Setting on
	page 85).
	• Check that the LFE channel is not set to OFF, or a very quiet setting (see Setting the Audio options
