	• The subwoofer receives frequen-
	cies below 80 Hz, from all speak-
	ers whose size is set to SMALL.
	• All speakers set to SMALL, receive
	frequencies above 80 Hz.

Most manufacturers provide a -3 dB specifi cation for their speakers. This is the frequency where the speaker's output has dropped by 3 dB. Set the TGIV's crossover to this frequency or above. If you cannot fi nd this, set the crossover to 80 Hz (the default).

Set your subwoofer's own cross- over control to maximum frequency or bypassed mode. If it is set lower than the TGIV, there would be a hole in the mid-bass, and bass information would be missing.
