I'm going to humbly disagree slightly here Mike.:sweat: It depends on what kind of a budget Warrant has to work with. IMO...More money than space = sealed. More space than money= ported.A ported sub would have more LFE and SPL then a sealed sub. If you want to go sealed, you can expect a lot less low end output.
Limited money + limited space = < :hsd:
Do you have a budget that you had in mind for this project? Also it seems like you are looking at doing a pair of subwoofers?
