Generally yes it will be. Most subs displacement (space taken up in the box by the subs basket etc) in a given size will be close to each other. For example I mean any 15 to 15 or 12 to 12 10 to 10 etc. So if your 8 inch sub requires 1 cubic foot and another 8 inch sub of a different brand calls for 1 cubic foot the displacements will not differ much from speaker to speaker of the same size. |
