OK, these are the specs I got from the web VAS 4.25 cu feet, QTS .35hz,FS 22HZ, I entered them into some program LSDP? I got it from the termpro site. Anyway I put in the the specs as it asked, then gave me the following:

Vas 4.25
FS:22.00Hz
Vb: 3.13 cu feet
F3: 24.87Hz
Fb:23.77Hz
Max Ref Efficency: 0.53%
app ref efficency: 0.34%
Ripple 0.11db
Vent Length: 16.35"

What does "ripple" or "max ref efficency" or "App ref efficency"???

Now I used that WinIsd pro program which gave me the port diameter, which I have no clue what to do?? But that's what the LSDP.EXe program gave me? Can someone help me out here and let me know if I am doing this right? This is a first time I have tried to make a venter/ported whatever you want to call it box.... How does this tell me what size of box to make? which cu feet do I go buy? and how to I know it's tuned properly?

If you can help me out that would be great!!

Thanks Guys!


Thanks that's all the website gives me....

 

Ok so no one can help me with this? Even the people who say " oh port it" "port it".. Least I can say Thanks to JeepBeats/MR2NR he sent me a few pm's to help out...

Thanks [img]smile.gif[/img] , I have been in contact with MR2NR and he suggested sealed box 1.25 cu feet... I have always been a fan of sealed just cause the "kick" it can give off, was never a fan of BOOMY bass but thought I would try something new, but I will leave it as always a nice sealed box.!

Thanks for the response Defro13 greatly appreciated as well!

 

Yeah, i was look at sealed enclosure on the winisd , and I forget the size I had but gave me a q of like .707 or something like that... from my udnerstanding you want around .757 do you not? Please correct me [img]smile.gif[/img] , .9 cufoot sounds like a tiny *** box for that sub lol..

With being a sealed box, they say it takes more power to get it to go, now in that case would you still just use say a 500rms amp for a 500rms sub? Or in this case would you use say a 600-700rms amp to have more then ample supply of power?

 

Nothing wrong with having more power on tap, this provides headroom and a good guarantee of not clipping the amplifier. I have never had a aluminum sub fail from heat generated by too much power.

 

What's my Q, if the box is 1.25 cu foot? I found something about year back that would show you your Q depending on size of the box, but I can't seem to find it now! If someone could help me out!

Thanks
