Not sure what you're describing here.

I've done ports on the opposite side of the sub and have had no problems, even did it in my own convertible. Maybe my ears just couldn't pick it up, but I don't know, I think I've heard my share of systems.
As a side note, I've seen many home theatre subwoofers also using this design.
