what kind of enclosure for a 15 Xcon?

[Notorious97200 339]

Hello,

I am buying a 15" Xcon for a friend of mine(he gives me the cash, it's really not a gift !!!).

He builds enclosure for some shops around here.

He has a 15" Kicker S15L7 in a 6 ft3 sealed enclosure with about 1300watts rms of power. It's the best sounding L7 I've ever heared : huge amount of bass, great low end notes,...

How can he achieve that with the Xcon ? Would it be better with a sealed or a ported enclosure?

Few people seems to use the Xcon in sealed boxes, how is the output in sealed boxes ?

He has a little trunk, the 6ft3 enclosure takes all of it! We made some mesurements, and here is what he can afford now : 35cm*49cm*80cm or in inches : 14" * 19.6" * 32". These are the exterior dimensions and give 4.9 ft3 total.

4.9ft3 sealed net or less for a ported enclosure ?

What are his best options for output and quality ?

Thanks for your help
