@CDW6212R Typically a sealed box will give much better sound quality than a ported box. (Ported boxes are louder, at the expense of only effectively producing one frequency). Randomly porting a box (not figuring out the port ID and length) is a gamble as you have no idea what frequency it will be tuned to.
