Advice for 15" enclosures?

I'm building a soundsystem for the first time, mostly for dub/reggae music. This is what im opting for so far:

Sub: 2x PD.154/2

Kick: 2x PD.123C001

Mid: 2x Fane Sovereign 10-300/2

Tweeter: 2x B&C DE 250 with B&C ME 45 horn

For the kick I will probably make a cubo kick 12, and mid & tweeter will be sealed enclosures. But i have a hard time finding plans for 15" scoops/bass reflex enclosures. Would the rear horn loaded from Fane be a good match? Or does anyone have plans for other enclosures? Any general advice on driver selection etc would also be appreciated.
