DD 3512 new box slams but what did I tune too

[cushmaca 10+ year member]

Box is 3 cubes after displacement and my port is 3" wide by 14" tall and 34" long. Sounds a million times better than the large DD box off the website. Digs deep finally and overall blends so much better. I just can't use Torres calculator and was hopping to figure out what tuned too.

The box is 3cubes after displacement meaning after the port... Those measurements he gave you are the port specs.

You should be tuned roughly around 30-31hz I don't have Torres either but pretty sure with 3cubea and those port specs should put you 30-31hz

Give the height, depth and width measurements instead.
