    ported box help

    Im building a ported box for my 2 12w6v2's. I need help on using how many port tubes/pipes (however you want to call it) per sub and which diameter and length I should go with. I'm aiming more towards SQ with a little SPL.

    Here are my options:

    1. 3" Standard Port - 5" long
    2. 4" Standard Port - 5" long
    3. 3" Flared Port - 5" long
    4. 4" Flared Port - 5" long
    5. 3" Flared Port - 8" long
    6. 4" Flared Port - 8" long

    or recommend me other options I should go with. Thanks!

    the length and diameter of the round ports are determined
    once you get the box volume all taken care of... i just built
    a box with a round port... lots of folks on the forum will tell
    you to make a vented box... which is a great option as it
    allows for a bigger port and can eliminate the chance of port
    noise... but my goal was to increase output and low end
    "authority" while keeping a small enclosure... i succeeded
    to my ears as now my single 12"SE sounds louder than
    my previous dual 12" SE's sealed... *****in' i know!!!

    having said that... a 4" port will help with port noise... but it
    will have to be longer than a 3" port... depending on how
    deep your box is i dont know if it will effect your decision...
    i built a 2.1^3 box tuned to 32hz with a single 3" X 6.25"
    circular port and i get little to no port noise... and certainly
    nothing i can hear in the drivers seat of my car... there is also
    the idea of multiple ports... say 3 3" diameter ports... while
    this will pretty much eliminate port noise the ports will be
    significantly longer thus forcing your box to be bigger for
    a given internal volume after displacements...

    ill stop there before i start rambling...

    Re: ported box help

    imo you lose a lot of options and flexibility with rounded ports. i'd go with a slot.

    Re: ported box help

    Slots are great but can be a pain in the arse of you do not have precision cuts etc. It is easier to use pvc ports but it is harder to manage the length with them. I'd use pvc pipe if it were my first time.

    Re: ported box help

    my first box was slot ported and since i did
    all the cuts with a jigsaw and circular saw
    i had quite a bit of "tweaking" to do to get
    everything together...

    my round port box was MUCH easier to build...

    i took a risk with port noise... but everything came
    out A-OK!!!

    Re: ported box help

    i dont understand why people have such a hard time making straight cuts....its a no brainer with a table saw, and if you only have a circular saw you just clamp down a 2 by 4 as a quite and youll get good cuts.

    i hope to get a table saw after christmas... my cuts are pretty darn
    accurate for a skill saw... but even pretty accurate can turn into
    way off when your trying to put together all the sides of a vented
    box...
