It's good and sounds good
Again very easy to follow. Detailed and great design. I bought the 6.5”, 8”, and 10” plans just to get started building my own boxes. Highly recommend for any beginners
Took me about 4 hrs total. Super simple instructions for a outstanding sounding box!
I bought the plans for the vented box along with the sub, built it as good I can but it sounds great and loud for the small amount of size it takes up.
