[QUOTE="THATpurpleKUSH, post: 8649958, member: 615398"] You misunderstood the port sizing, in the manual it says a 3 inch round port that equals 7.07 sq in of port area. Round ports are more efficient than rectangle shaped ports so you would need a larger port opening like 16 sq inches of port area per cubic foot which makes the box a lot bigger because the port is so big. Since you are a beginner and they are already telling you to use a round port, stick with the round port. If you do it right you can tune them to your liking and they are easier to work with and calculate around. Do something like this: 24 wide 14 tall 15 deep, 3/4 baltic birch or equivalent or mdf 4 inch round port either flared aero or pvc pipe and a 9-11 inch port length. If you use pvc pipe you can mount the port to a piece of wood and use nuts and bolts to make it removable to play with the port length. That will give you about 2cf tuned 35-40hz Here's an example of what I mean: [IMG]https://i.imgur.com/540FzVX.jpg[/IMG] [/QUOTE]
