Quick question about sub boxes, Just curouis Options

[pepsiman]

im thinking about getting a pioneer 10 inch sub and i have read about how premade boxes are bad. I was thinking of making a box (with alot of dad's help lol) or getting a build a box thing from walmart. Ive read many times that premade boxes are bad since each sub need its own uniqe amount of airspace and the recomended amount of the pioneer is 0.65 ~ 1.25 Cubic Feet and the build a box is .75 cubic feet. So does that mean the build a box would be ok or would i be better off building one?
here is the links two the box and the sub:

BUILD A BOX = GARBAGE!!! don't even think about buying, 10" box from best buy will do just fine, i think most of their's are 1.00cu ft, if you don't want to pay that money then build your own, 3/4 MDF <-- this is a must, make sure you measure the interior volume not exterior, and DOOR/WINDOW sealant from lowe's works amazing to seal it, put it on your finger and push it into all the joints, pre-drill holes, then use screws
