Ground zero subwoofers all produce sweet smell?

[QUOTE="SlugButter, post: 8839178, member: 678073"] I did a box recently for a sundown 12 with dual 4 inch round ports. The box was tuned to 30 HZ with 1 port and 45 on the other depending on which port was plugged with an expandable drain plug. I haven’t actually seen any scores from it or even heard the sub in my enclosure, but he claims it meters quite a bit higher at the 45 HZ port tuning, and does decent on music and floating plastic bags in his window with the 30 HZ port. What I wanted to do was keep both ports the same length, so when you leave both ports open it would be tuned higher with double the port area, and 1 port closed would be the music tuning, but with both ports open with both being the same length as each other, it only raised tuning from 30 to 38 I think, and he wanted 45.
