Yes, phase is important for low frequency, and most active x-overs have phase invert switch for subwoofer out.

I am currently using Eminence 12LF in some subs, but I would hear them also in 2 way box, so can you now tell me what diameter for tube and how long should I use in your project? For Ei and Eminence.

It is not difficult to build, and bass is very powerful. 😎
