Very pleased.
I'm really happy with the box. Subs fit snug, and the box is carpeted very well. It's legit, rock solid MDF. Overall, a great value. I would recommend this box to a friend.

Good box for the price..
Recieved the box in a well packaged freight box. Unloaded box and noticed one spot on the exterior of the box where the carpet was missing, also looked at the caulking of the box and noticed there was quite a few open areas. I went to my local hardware store and bought some caulk and re-caulked the box to make sure for a good seal. Overall a good box that may need some extra sealing but overall great box for the price.
