Great, solid box
This box is well built. All joints are sealed on the inside, and no air leaks can be heard. I have a 10" pioneer (TS-W252R) in there, sounds amazing.
No problems with the terminals, they just screwed down instead of being spring loaded. The sub fit in perfectly snug. Arrived on time. No complaints or problems.
