Can subwoofers share airspace?

If the subwoofers are in a shared enclosure of two cubic feet then they will share the air space between them and each will operate as if it is in a one cubic foot enclosure. That’s a fact. But if the subwoofers are not identical and do not receive an identical signal this will not hold true. via

What is subwoofer displacement?

The displacement of a subwoofer is the amount of air space the subwoofer itself takes up. Once the subwoofer is in place, this amount of air is no longer available inside the enclosure. via
