How to integrate phase of a subwoofer with mains?

Hi all, was wondering if you guys could help me with this problem. I have a pair of JL Audio F110's. I know how to integrate the volume with my main speakers (use test tones and an SPL meter) but I am not sure how to integrate the phase of the subwoofer.

The phase on the sub is adjustable from 0-360 degrees. What tools do you use, and how?

You probably dont want to hear this...but the tool I use is my ears. Most of the time in my experiences, there is no difference. Acoustically speaking. Technically, there are measured differences in reinforment of lower response vs cancellation. Ears...you dont need anything else for this exersize.

Start with a test tone that is below your crossover point of your mains. Set the volume to a comfortable level. Using a SPL meter at the seating position, adjust the phase of your sub that produces the highest output...you're done. Now comes the fun part of sub positioning, crossover points and volume. Good luck, and have some fun.

BRF's approach is a good one. Sometimes, though, it is easier to do that but find the setting that produces the lowest output as the null can be sharper/more defined than the peak. Then, subtract/add 180deg to that.

You might try both.
