 The only problem may be the length of the port is pretty long and it can pick up resonances inside the tube. I have used as well as many others a 6 inch port at about 27.5 - 32 inches and it works great with no chuffing. |
The length I suggested is within the acceptable limits. And sure many folks have used 6" ports with 15 drivers and had no issues, including myself. That doesn't mean the OP should settle for 6" when 8" is doable.
