Sealed
is there anyone out there with a pretty good knowledge of car audio who can tell me the difference between the two boxes and which would be better for deeper bass? |  |  | | 05-01-2008, 01:53 AM | #2 | | That's not Millpoint Blue Join Date: Apr 2005 Location: BNA Posts: 3,161 |

I'm no professional, but from my understanding ported boxes tend to be louder and sealed tend to have better sound quality. I've had both and prefer sealed. | | | | | 05-01-2008, 03:31 AM | #5 | | Senior Member Join Date: Oct 2007 Location: Eugene Oregon Posts: 6,182 |
ported causes more air to be produced which equals more bass. i highly recommend ported! makes a huge difference in bass and im sure your going for more bass than a perfect quality.
it also depends on what kind of cubic space your sub needs and also how the box is ported you dont simply just slice a hole in the box and expect ported sound __________________

comparisons between a fosgate 10" sealed and a 15" ported tube
The tube was louder and more "raw"
The sealed had a much more richer, heavier sound.
I reckon the difference was because the fosgate was a better quality unit, but if the amp (1000 w ) that was running the tube had been hooked to the sealed, then the sealed would have took it.
The ported seemed best for Drum&Bass
The sealed felt best for R&B. __________________

ok, I have a sealed box right now because it was the cheapest I could find, does anyone know how to port it? I know I have to cut the hole and add the tube, cut to a certain length but I'm not sure about the details (tube size/length) this time I did search and couldn't find out how to figure that stuff out, it's a 12" 500w RMS dual voice-coil sub running off a 480w amp in a 1.3 cu. ft. box if anyone knows how too calculate it, or would I just be better off buying a ported box? | | | | | 05-01-2008, 11:09 PM | #8 | | Senior Member Join Date: Oct 2007 Location: Eugene Oregon Posts: 6,182 |

f*ck!!! too much stuff to read  I guess I'll just keep my sealed box since I do want the fast-hitting bass, plus I don't think the el pipe-o will fit without my ti looking like it has chimneys | | | | | 05-02-2008, 12:11 AM | #13 | | That's not Millpoint Blue Join Date: Apr 2005 Location: BNA Posts: 3,161 |
