So your port is just a hole in the box???

You might want to design a proper box for those guys... //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

I don't feel like searching the whole thread but what are the parameters of the speaker?

 

[osix 10+ year member]

here is some data of the Sub

Qts 0.630

Qms 2.430

Qes 0.851

Vas 1.607cuft

Fs 34.7hz

Xmax 11.2mm

Dd 9.23in

Sd 66.91in^2

Le 0.40 mH

BL 7.91531

SPL 85.53dB

12" DVC 4 ohm

Hope this is helpful

The Space i use now is about 3.4 cuft - 3.7 cuft I can reduce it adding sound foam into it .

Try something like 3 cuft tuned in the 30Hz range...

It would model much better in a sealed box to tell you the truth.

 

[osix 10+ year member]

i had already port it . and the hole is kinda hard to seal it well . -

any advice on vented ?

what port length would you advice ?

all kinda suggestion . advice and help is greatly thankful

 

[joetama 5,000+ posts]

Vented is ported....

Let me run some numbers to see what i get...

 

[joetama 5,000+ posts]

4.4 in diam 11.89 in long... Makes 30 Hz....

Your other port was only tuned to maybe 45 Hz which would give a very hard spike in the response...

 

[osix 10+ year member]

i got about 9" on the port length

i will try it tomorrow and see how it go
