View Full Version : Building a new box

I'm starting a new box build for my 2-15" Fi bl. I just wanted to check my numbers. Box will be 40" wide 27" deep and 20" tall. Port will be 7" wide in the front center of the box and 18.5" tall. From my calculations after speaker and port displacement it will put me right around 3.1 cuft tuned to 33hz with 129.5 cuin of port. Is this enough airspace for the subs. I know they like 2.8-4 but i'd rather be close to the higher side of that and with the space i have i cant get any bigger. Let me know how this looks.

i know center ports like this dont yield the most output but i want it to look good at the same time. plus i think the 2-15"s will be more than enough anyways.

anyone with any comments? will 3.1 cubes be enough or should i try to squeeze more?
