Graph Deciphering

[bcarpenterfhl]

I did my box by hand, then plugged them into Bassbox Pro. (thanks to all those who helped me on this forum) after plugging in my graph specifications , i then loaded my driver from the database. BBP6 produced a Response graph like this:

what does it mean. i think i read somewhere that the purpose is to achieve a flat line, or something of the sort. that line is no where near flat.


(graph based on 3 JL 10 w3v2s, and a ported box tuned at 33.71 Hz, with a Vb of 3.595 ft. ^ 3)

do i put 33.7 for the +3 db frequency. if not what do i put? i have a big suv.

[bcarpenterfhl]

ok well now it just looks like this:

what does all this mean? is it good or bad?

[bcarpenterfhl]

its not gonna affect how i build myself. i would just like to educate myself as much as possible?

FYI, everything after whatever you set your lowpass filter to doesn't mean a thing. Same goes for anything below your SSF frequency.

[bcarpenterfhl]

ok i did that. but it still looks the same, just on a different scale. i can repaste it again....

You do realize your sub shouldnt play anything above 150hz, right? Therefore making the whole right half of that graph useless..."~ANeonRider"

[bcarpenterfhl]

yea i do...my reason for posting this was to learn what all these figures meant, but i havent gotten an explaination yet.

[bcarpenterfhl]

now it looks like this:

now does it look right? also could someone simply just tell me what this means?

[bcarpenterfhl]

is there any reason i should do that and change the plans i already made?

[bcarpenterfhl]

This is a comparison between my current sealed enclosure and the ported one i designed and plan to make:

Pink- Ported Orange-Sealed

Does this mean i'll be getting a that much of a substantial difference in response switching to a ported enlosure?

[bcarpenterfhl]

k thanks. sorry for the dumb questions.

[bcarpenterfhl]

whatever its all good. im making the ported box more for my love of building sh*t rather than the sound of my subs, although thats a plus.
