XXX 15 Box Ideas

[chinny]

Okay, i will be ordering an XXX 15 or 18.. iam leaning towards the 18 more... and i was wondering what size box will squeeze me out some more spl out of the sub, i want to tune to 35hz, i was thinking something along the lines of 5cuft tuned to 35hz, what do you guys think, i only want replies of people who have HEARD or PLAYED with the sub..kthx. :up2somet:

[_DjScrew_]

i did mine 4cu @ 28hz and it's great. just my two cents....

[snebes]

Do you want it to sound like *** or have some sq too?

[chinny]

I dont want it to be ALL SQ thats the thing, i want to have SOME SQ while having a lil more spl, hence the 35hz tunning... i might do 4.5cuft tuned to 35hz or i might just be getting an 18, single sub setup with an 18 would get peoples heads turning... hows your 18 doing?

snailshell?

[chinny]

snailshell?

Possibility.

[chinny]

hmm, im gonna look into the 18's

[chinny]

does any 1 have the WinISD parameters?

[chinny]

any more input?

[vasilios]

my xxx15 is in a 4cu.ft. box tuned to 30Hz right now and sounds ****** great...i should be receiving my snail shell sometime in the next week. ill let you all know and maybe get some pics up..it should sound a lot louder/better than the box i have now, but yeah great effing sub...hits the lows well and gets stupid loud.

[bamaboy]

my sub in 4.5 cu ft to 32hz is great, loud enough for me

I had the exact same setup. I can't imagine anyone needing anything louder for daily driving.

[chinny]

so many options... but im leaning more towards the 18

[80INCHES]

last week i designed a bandpass box tuned at 35hz and it got stupid loud and it the lows nicely...but it was with 2000watts

80

[chinny]

i will give it 2000+ watts... but im leaning toards the 18 more..

How is that for an XXX18 7.5cuft NET @ 35Hz... can some one go over the calculations to make sure everything is good to go since this is my 1st box ever made and i really really **** at math, i can barely use a calculator aside from the positive,negative and division.

[Harrison486]

What were going you for?

What size after displacement tuned to what?

And what is the displacement from a 18" xxx

The port is suffocating. I just ran the calc, and it needs like 172 sq in of port area, Im not even gonna run the length....it will be scury

[snebes]

And 18.5" on the baffle may be a little too tight. I would go with 19 at minimum from the looks of mine (old claw basket)....and a double baffle (1.5")

[chinny]

****it.. i knew i had messed up.. gay.. im not even going to bother this ****

[chinny]

displacement for the xxx18 is .25

[Harrison486]

Ill design you a nice one for the right price :up2somet:

[chinny]

Naw, i dont belive in that "You pay me and ill build you some plans" i never did lol, not towards you or anything but i think were all here to help each other so why charge? Are people in such needs for $5? I mean come on now people :/

[chinny]

Ill just have to learn it but before i have to learn some math.

Hes talking in chinenglish? All that math gives me headaches and i dont know what it means lol..

[Harrison486]

I know what you are saying...

I tried to learn from his thread first but got nowhere

[chinny]

true that, but if you wanna help me then be my guess, hopefulle ill learn this time.

[chinny]

How about the following....

-Box Dimensions
18.5Hx40Wx24.74D

-Port
17.5Hx5Wx21L

This gives me a tunning of 34.72Hz with 7.5cuft NET and 8.8 gross, what do you guys get?

[chinny]

wow bbp6 *****... my calculator is starting to work..

[chinny]

bump to harrison for helping me out

no, it doesnt. i bet 70+ sq. inches will be just fine.

[chinny]

i will be using 120in^2

[chinny]

btw i finally learned.. now i can help the poor!

[bcarpenterfhl]

i will be using 120in^2

more the merrier. :p:

[chinny]

Go with either 4.5 cu ft (after displacement) box tuned to 32Hz

or

snailshell. ;) :) ;)

Yeah, im going for an 18 now.. i though that if i had the money the power and the space then i might as well get the 18. I will be doing 7.5 after displacement tuned to 35hz with 120in^2 of port area

[james33440]

^ why not make the port a little longer for a 30Hz or 32Hz tuning? ;)
