Hey guys, before I get to building this box I just want to run it by a few of you on here. The subs will be powered by a Nendo S1500.1. Anything that needs to be changed or is all good? Thanks for your time.

port is too small. shoot for 14 square inches of port per cube with a slot port, and 3 cubes net.

very GENERAL rule of thumb for porting:

slot port: 12-16 sq in per cube

aero port: 9-12 sq in per cube.

don't always go by that, but it is a good starting point.

To keep port velocity reasonable, I would shoot for 50 sq in of port area. I came to this number based on your box volume, tuning, cone area, and amount of power you are going to run.
