I have a few quick question about the sub box that I am going to be building. First I have two SA-10 D4's wired down to 1Ohm, being powered by a SAZ-1500V3, currently have a crappy prefab enclosure. Though the subs still sound great I know they can be much louder. I have used a few online calculators as well as design software to build a basic ported box. I just want to verify that the box design I have will be sufficient. I've been playing with some numbers and I'm curious about port recommendations as far as width and length Current Box design is a simple ported box with a side slot vent, subs are sharing air space. I'm using RE audio Box calculator specs are Width - 36" Depth (top and bottom) - 12" Height - 15" Square port width - 2" Square port length - 6" Box volume comes to - 2.53 ft^3 Tuned frequency - 35.15 Just want some advice or confirmation that my box design will suite my setup Thanks, Brandon
