Default Small volume and low tuning?

How are you guys doing it? Box is 1.5^3 tuned to 25hz.

Tried plugging it into 12volt's box calculator and for any resonable length of port it want a width of like 1" and height of 5". Is this correct? Can anyone shed any light on this?

1"x5" is way to small, port area is only 3.3 sq" per ^ft.
2"x11"x58" will have port area of 14.7 sq" per ^ft tuned at 25hz.

Here is a design I did with 2 1/2" x 10" x 46" tuned to 30hz.

just go with a bigger box , and why would you need to go that low with a single ten? mid 30's make so much more sense.. just sayin you dont need to tune at the fs lol


i have used a pair of similar tens in a 4 cube box tuned to 30hz, port was something like 3 w 12 h 28"..ish? deep, played really low for tens

try a 2 cube box port 1.5w 12t 20(ish)d

I'm just going by the recommended specs. I'd love to see if they really do dig down as far as they say it will.

Plus I'm using this to train myself on box design and sketchup, the sub is just sitting here collecting dust so I figure I'd give myself a challenge.

edit: also, f3 on these is 22hz so I'm not actually all the way there
