Not to shabby.
This box design, if followed correctly, makes a very great deep bass enclosure for not only traditionally mounted but also inverted subwoofers. Only tip I’d give is to make sure if you do follow the design plan to go back before you put on the top of the box and place 45’ degree corners in all spots with a 90’ degree wall to keep the sound moving freely.
Good design
I wish there were more star options because 5 isn't enough!
Cheapest downloadable plans I found and no corners were cut.
Super easy instructions anyone with a saw and pencil can put this box together.
Now lets talk about the sound...
AMAZING! I have two custom high output 8's and this box did what I didn't
would be capable of my 8's!
Long story short, don't second guess this purchase.
I will definitely return in the near future!
I ordered these plans as a starting point for the box I was putting my BMW wagon. I just wish that it came with the port length, port area and box volume (both net and gross) listed. Other than that, it’s an easy plan to follow.
