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?

A bit off-topic and this may not contribute to the thread.

I find that most musical material differ in bass frequency output. Some albums will have more bass and sound boomy even without the subwoofer integrated into the system(room acoustics affect this to a certain extent) while some albums will need the volume/crossover on the sub to be turned up considerably high above the half-way point on the volume knob of the sub in order to feel the bass. As such, I am unsure whether setting-up the sub accurately using test tones as suggested by most folks(which is supposed to be the correct method anyway) will apply to all conditions and all albums, both CD and LP format.

I don't know about others but the settings on my subwoofer are always changed periodically dictated by the particular CD or record that is played. Any insight on the proper method to professionally set up the subwoofer would be appreciated. For those who have professionally set up the sub using test tones, do the settings stay put for all listening material?

p/s: I have a Radio Shack meter and test tone CD.
