Adjusting Subwoofer volume
Using the A/V Receiver's test tones ONLY what is the best way to adjust the volume of the subwoofer?
I have a Yamaha A/V Receiver with the crossover set at 80, the sub (JBL SUB 12) is turned to the highest crossover setting. All speakers (5.1 setup) are set to small. Sub's volume is set at the next mark past the half way mark. I have the A/V Receiver's sub output volume set at +2. When I run the test tones, the sub's volume is much lower than the other speakers yet when listening to a source the sub's volume seems ok. I don't understand why the sub's volume is low during the test tones. What am I missing here?
