Does the shape of a Sealed box matter as much as it would for a ported box?

I'd like to build a box that has a dip in the middle to better utilize my trunk space, I was just wondering if there are any issues with making a non-cube like sealed box for my dual 10's would be a bad idea?

__`` __
lx \__/ xl
l______ l

x = Sub
Thats a very very roough idea of what I had it mind (the dip in the middle is so I can fold the seats down and but a snowboard or 2 in). and it's obviously not to scale

 

no it shouldnt

 

Nice, thats what I wanted to hear haha.

 

yeah its still sealed and the air is being compressed and expanded from and into every nook and cranny

 

an egg shape inside the box is the best but oes not matter that much
do you have the room to face the subs in the hole at each sub
__`` __
lx \__/ xl
l______ l

 

do you mean having both subs firing into the box (magnets outside the box)?

if so no I don't really have room for that

 

inverted looks cooler too lol

 

that would be cool to have the 2 subs on the angled parts

would that give any different sound at all?
