Do you have those drivers already?
They're really intended for use inside a car, where they have a large (albeit leaky) box, and lots of room gain in the low frequencies.

It's probably possible to make them work in a domestic space, but it might not be easy. If nothing else, be prepared to add baffle step compensation in the form of an inductor and resistor in parallel, in series with the woofer.

if you can find its parameters then something can be designed. I'd assume Qts close to "1" for car use. Sometimes a closed box can be made to extend lower and more flat with a series capacitor. "Aperiodic" might be another option.
 
Can anyone share the exact dimensions for sealed or ported box?
No. To do that you need what are called "Thiele-Small Parameters" and then we could help out exactly. Unfortunately, at MAXIMO ULTRA - Morel
I see no such information. I worked in autosound as a loudspeaker engineer among other things, and this is not always provided.
(a) Ask Morel if they have that, if so post
(b) If not, I'd advise a sealed box. A ported box is too random to design without knowing any parameters at all, you could end up with a horrible boomy mess. I don't recommend "aperiodic" either (it's just a very leaky port) for similar reasons.
(c) I'd make the sealed box 1 or better yet 2 cubic feet. Put cross-bracing and anti-vibration coating inside, and stuff with oh maybe 1-1.5 pounds of fiberglass per cubic foot, or "Acousta-Stuf"
(d) Don't expect much very low bass unless you get incredibly lucky
(e) Flush-mount the tweeter, use the stock crossover. If anyone posts "those are designed for car use and crossovers tuned for in-car" they are mistaken, all that stuff is designed to sound best on a dealer's demo board. Some crossovers may indeed have settings for different mountings, but the default will be for dealer demo.
Good luck!
