Tuning frequency will be dependant upon vent area, enclosure size, and vent length.

If you have one vent already and you add another of the exact same dimensions, you will raise your tuning frequency due to great vent area and a decrease in enclosure size.

so if i m trying to lower my hz i shouldnt do that ??? thx

Yes. Making the port smaller is what you want to do.

 

[Tirefryr 10+ year member]

Not always. A decrease in vent size can cause vent noise. How about you tell us your current enclosure specs, driver, and power. Also, WHY do you want to lower the tune?

True yes, but he doesn't want to build another box and he cannot add to the port as of now I don't believe //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Different drivers altogether. For simplicity's sake, I'd go with the manufacturer's recommended enclosure of 2 cubes if possible. I'd definately add more vent area though and lower the tuning.

look i cant do that cause i really really dont want to take up my trunk so do u think that h2 box will still be louder and sound better than a reg. sealed enclosure?????

If you truly cannot use that box, there is no point in putting it in a different driver's enclosure. That's the entire purpose of building a custom box. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Have someone make a design for you, it would be better than just guessing with numbers //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
