Shared box for BTL's or BL's

[noidle22 0]

I have a box design in mind (i just need a car to see if it will fit or not) which has two either 15 or 18 inch (depending on available room) BTL's or BL's. I am not sure though if these subs are designed to be able to share a box together. I was originally going to run just a single BTL 18" in a 7 or 7.5 cu/ft box, but i wanted a more good looking design, so, as an example, are you able to run two BTL's in a box of volume 14-16 cu/ft? Or the equivalent volume of the BL's?

I'll try to draw what i want it to look like on a CAD program or something, but i would like to know if it possible first before i start buying materials.

Thanks

Do you mean a shared chamber? I see no problem with that.

Shared chamber? Is that the proper term for having two subs in one box? Cos thats what i was talking about. I didn't think there would be a problem, but i know that most top-end FI subs aren't meant to be used in a sealed box, so i thought that there might be some other thing about not running two in the same box, even if the volume of the box is acceptable.

Thanks
