Then why did you list prices at all?
Sealed was my choice when I started DIY'g subs, not because it was better than ported, but because for me it was more manageable to build (being a rookie woodworker with modest facility/tools) and move them around too....so I went with several sealed altho my original thought was ported but the boxes for my drivers were more complex to build and a hell of a lot bigger/heavier. I do have plenty of room for the larger subs, too. YMMV.
