So the box I built for my dc lvl4/5coils is supposedly tuned to 32hz

And I'm not pleased with it. How would I go about making it tuned to say, 36hz without tearing apart the box?

Give us your old specs.

[Stephen]

shorten the port

[EricM9104]

aeroport or slot port?

[k3n12ock]

Don't laugh

Might be building a new box with a 6" aeroport designed by Nightshade in the near future.

A good idea is to start a new box, and dont use the RE calculator that is so off it aint funny.

Search for Exposports calculator on SMD.

Actually I tested it a couple times between both calcs, they're the same, but the Re doesnt account for displacements of the sub or 45s, or braces. So just use the ExpoSport Calc because it does

I got 4 cubes even @ 37hz with 11.5 sq/in a cube.

On the small size for port.

Well with his box between the 2 different calcs box is tuned under 30hz.

Damn. Talk about way off. I'm not sure what to put in the sub displacement on the Expo calc as I don't know what a lvl4/5 displacement is. If someone could just whip me up something real quick and screen shot it, I would appreciate it. Tuned to whatever a lvl4/5 coil is suppose to be tuned to. Max dimensions: 36"l x 17"h x 17"D
