10w6 ported or 12w6 sealed

I currently have a box contructed at 1.30 cubic feet per chamber.  I was thinking about getting the JL audio's 12W6 which would be perfect and no mod's to the box, however, I noticed the 10W6 requires very little space for a ported enclosure. I could easily modify to make it work within specs. I listen to mostly reggae / Hip Hop / dance type music.  Would I benefit from a ported enclosure (2-10's) even though I would have to modifiy my enclosure with ports/slots, or would It sound and feel better with the 12's sealed? Thanks

it depends, what do you mean by modify? you're not just going to cut a hole in a sealed box are you? can you fit the right sized port inside your box. i say, if you are going to go through the trouble of moddifying a box you might as well just build one to fit. as far as the sound goes, a ported box will fit the reggae and the hip hop music very well but it might sound so great with the dance music if it is a fast beat. the sound you get from a ported box really depends on how it is built and tuned which is mainly why i say you should build one instead of modifying what you have. try going sealed first and if you dont like it make a ported box.

When I say modify, I mean adding the right slot configurations.  Definitly not adding a hole to the box.  The original question had to do with a sealed 12 inch verse a 10 inch ported.  Designing the ported box really isnt a issue for me, its trying to figure out what would sound better for my application. 2 -12 inch sealed or 2-10 inch ported? And I never seen a subwoofer that needs only .75 cubic feet ported. The 12 inch model needs double that, 1.5 cub ft

Yea, I figured I'd be better off with the 12's. Hope the sound quality of these subs are as high as there price. Thanks.
