what type of enclosure would I need, right now I got a 1.0 cu. sealed and the sub is ok. Would it be better if I put it into a ported box that I made for my old 12" Vega, (its a big box)

 

http://www.audiobahninc.com/tech/200..._box_specs.pdf Looks like for sealed they recommend between 1-2 cubes, for ported it looks like 1.3-3.15 cubes. Have to measure out the ported box you have and see if it will work. Good luck. [img]smile.gif[/img]
