I'm building a new ported box, what's the best freq to tune the box too?? I listen mostly too dance, trance and some rap.
The sub is a 10" OZ-Audio 250L going to be in a box roughly 1.5 cu.ft and in a Dakota Club Cab.

Thanks,
Anthony

 

Which 250L's are they, these ones? http://img.epinions.com/images/opti/...resized200.gif

 

If you check out my sound domain site you'll see the pics of them. They're about 10 years old so the link you posted are the newer ones.

I have a listing for a 250L from 1997, probably that one. I ran it through Bassbox, 1.5 cubes vented they suggest tuning it to 27hz, that seems low to me. Maybe try for 35hz, which would be a single 4" round vent, 15.2" long. Hope this helps, anyone else?

 

BBP6 recommendations :

1.3 ft^3 - 28.1 Hz
5 ft^3 - 18.9 Hz
7.1 ft^3 - 17.2 Hz

The 1.3 ft^3 - 28.1 Hz enclosure looks pretty decent ...

Like JeepBeats said, for 1.5 ft^3, it recommends 26.9 Hz ... To get that, you'd want a 3" port that is 15.5" long ...

I'd experiment with other non-recommended options, but I'm tired and lazy and heavily drugged because of surgery

Thanks Guys!!

I was thinking of tuning the box at around 30-35Hz. I wanted to ask before I start building it.

Thanks,
Anthony

 

No problem, maybe start it off at 30hz, and try shortening the port to raise the tuning frequency until you find what you like best, all it takes is some spare pipe.

 

Hey Guys,

I'm using WinISD beta to work out the vent size and all, but I think it's not right??

The box is going to be 1.5 ft^3 With the port tuned to 32Hz. The program gave me the port size of 3" by 10" long. Is this right??

Thanks,
Anthony
