4 Atomic Apxx 15" 4rth Order Bandpass Wall Build


Recommended Posts

Carpet = remove, on the backside where your subs mount = roundover, port = roundover but more smooth like fiberglass, all the corners of the box should be rounded or cut long triangles to go from end to end. Then fiberglass resin the whole inside of the box for smoother air movement. All those things will help. I realize that removing the carpet is not an option for most but try it if you have a meter handy and see the difference. Also do you know your exact peek note?

x2. some 45's and glassed inside will help alot.

looks great though.

will they all load equally with the port on one side like that?

-Drew

they should, once its built i've gotta shrink the box's and make the port bigger to fine tune it (if that makes sense) but im hoping it will load fine

im not a fan of finishing box's or making stuff look nice i like the ugliness that follows the loud

and they were ran off the battery with custom aluminum distroblocks i'll find pics in a bit i took out my G31 and unhooked all the wires the other day cause i believe the battery froze or somthing :( but i will have pics up in a bit
