hey guys im needing some really quick help! i planned on using subwoofer tools to design my box but their site isnt working on my computer and i need them asap! the box needs to be 5 cu ft tuned to 38hz

30 wide by 17 tall by 25.5 deep it had 69 sq in of port area since i raised the xmax more than what it really is..

ah i believe i just figured out the port.. i think it is supposed to be 15.5 tall and 4.5 wide.. that would give me 69.75 which is what i had for port area.. so .75 on top and bottom of that gives me 17 inches tall (my main worry) so i think i might have figured it out.. im going to spend a few minutes and do the math again to double check myself.. thanks for the help and if you would like to draw them up for me or continue to help me with the designs that would be greatly appriciated!

Give this a shot. Seems to be as close as we can get to SubwooferTools. I am going to be using it when i build my next enclosure.

 

[ladi3sman55 10+ year member]

well i gave that a shot but i couldnt get the tuning freq high enough since you cant change the sq port length #1 highest i can get the frequencty is 32hz //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif i know i gotta shorten that length but i dont know how much.. lol

 

[ladi3sman55 10+ year member]
