Ok so I am wanting to get a better sub for my theater system. I want to build a box for my 8" sub. I want to know what is the best way to build the box. I know that the boxes to the subs are designed different to produce more bass from a small sub. Any one suggest a box design or something to get alot of bass from my sub. Ported, Sealed, Bandpass, and help would be appriciated.
