Easy to build - Great packaging
Assembling the box was straightforward, though it lacked the promised instructions. The packaging arrived safely from Nevada to Virginia. I used Gorilla Wood Glue and 1 5/8” #6 wood screws; the box’s predrilled holes made assembly easy. Printing the box drawings from the Down4SoundShop website helped. I added screws for the port pieces and flipped the etched panel inward, but the box still fit together well and performs as expected.

Great quality box
I had 4 Skar EVL 6.5’s that I need a box for and I found this one. I was a little worried that it would get damaged in shipping because it was going across the country, but it was packaged very well and arrived undamaged. Assembly was a breeze, just needed wood glue and screws. It even had pre drilled hole. Also this thing slams, it sounds great.
