Shallow vented sub box?

Hi,

Thanks!

Need dimensions of the box and also dimensions of the port. usually with small ported box the hard part is getting enough port area. especially a round port.

I did not run the subs specs but it looks like it would perform in a sealed box well.

Might not have been a good choice, since it looks like the sub is a space hog (at 2, if not 3 cuft net ported).

Hi, I think I would go for a sealed box (Width 40cm, lenght 25cm, depth 10cm). Would this work?

Ported boxes have better efficiency in smaller enclosure applications than sealed boxes. Where are you going to put it? Try extending the width and height of the enclosure...that should be able to give you room for a shallow enclosure setup.

Try WinISD it might help.

There's practically no depth there. If that's all the space you have to work with, I'd look into bass shakers (aka tactile drivers).

It's fine to do, just be sure you have some space from the magnet to the wall of the box.

I'm building a shallow ported box for a JL 10TW3 right now. I'll have it posted next week. But my box is 5 inches deep (external) and it's a non-issue.

Passive radiators might be a more feasible option.

...and lots of these:

The speaker is 11cm deep.

I'm not sure what the company suggests, but usually it's about 12.5mm space behind it.

So a box 12.25 deep is adequate. if your box must be shallower you can use a spacer, but it could look a bit goofy.
