RECEIVER OPTION #1

The receiver’s LFE or SUB output is the input to the subwoofer (most common case): 1. Select that you have a subwoofer.

2. Select the number of speakers.

3. Select the speaker size as SMALL.

4. If you don’t know the low frequency limit of your main speakers, use 80 Hz as the crossover point. The lower limit of the main speaker’s frequency response is usually listed in the speaker specifications as, for example, “3 dB down at 45 Hz.”

In this example, double the value (45 Hz) and use the doubled-value (90 Hz) as the crossover frequency.

5. Adjust the LFE /SUB output level to 0 dB.

6. Go to the Connect Subwoofer instructions next.

RECEIVER OPTION #2

The receiver’s unfiltered/full frequency range R and L output channels, not its LFE or SUB output, is the input to

the subwoofer (less common case).
1.	Select that you have NO subwoofer.
2.	Select the number of speakers.
3.	Select the speaker size as LARGE.
4.	If the crossover frequency option is available, double your main speakers specified low frequency
	response value and select the result as the crossover frequency. If you don’t know the low frequency
	response value, use 80 Hz.
5.	Go to the Connect Subwoofer instructions next.
