    Graph Deciphering

    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)

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

    Re: Graph Deciphering

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

    Re: Graph Deciphering

    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?

    Re: Graph Deciphering

    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.
