I have never tried a purpose built loud box. I always thought I could get good numbers with a daily box, that hasnt worked out.
We will see this weekend if my vision works out. A tick over 3 cubes net with a 7 inch aero tuned at 39hz. I guess it's going to be real peaky but I don't care anymore.
38.47 square inches of port area. 12.63 per cube.
Wish me luck
