They aren't bad I have one for sale dirt cheap if u want it its never been used perfect condition. The sound isnt bad. they are really solid and will hold up with your vr's....anyway hit me up if ur interested ps. dustin doesnt know what he's talking about its made of 3/4 mdf so you know its not flimsy. plus its up to you if u seal it tight enough, its not up to the box
q logics are CRAP dont get ripped off by buying one of those. But its your choice if you do get it make sure you put silicone or liquid nail cause the glue they use sucks and would end up leaking and sound like crap.
If you want to order a box, try Klaus Audio. They will build custom boxes to the specs you need with 3/4" MDF. They also seal the boxes themselves which is a no-brainer.
