It would also double or triple the box price to build curved ports with a slot port using kerf cuts. There aren't many box builders around who could even build it, much less some guy you sent a design to. Not many car audio shops can do a box of that level. It just isn't realistic to design it or build it, unless it's for a super high end build that costs ridiculous money.Curved ports are not impossible. Not always easy, but not impossible.
