    Port Questions...

    When you use some online port calculators for round ports, and it gives you say 12" for the port length, is that for EACH or do I divide that by 2?

    ALSO -- How do you know when you should use 2 ports, or just 1 for round ports?

    Re: Port Questions...

    You would determine to use more than one port if you need more port area.

    And the port calculator will only give you an answer to a direct question. If you list one port it will give you the length for one port. If you list two ports than that is the length for each port...

    Re: Port Questions...

    Okay, cool.

    This is my dilemma if anyone can pitch in thier 2 cents...

    I have a 2.3061cuft box (excluding port displacement, but including woofer displacement) with a single Type-R in there...

    Id like to have 2 ports, just for the looks mainly --

    4" port would (Estimating on port area taken down to 2.0cuft) = 34.7inches long each -- This is way too long for the space i have available.

    2" Ports would be (Estimating on port area taken down to 2.1cuft) = 7.5" long each... this works, well.

    BUT -- Am I going to get port noise?!

    Hizelp!

    Re: Port Questions...

    Port noise - YES.

    Use at least two 3" ports.

    Re: Port Questions...

    K, thisi s my mess...

    The ports can go UP, or FORWARD (Sub is facing up)



    Woops the dimentions are incorrect for measurements for #2 triangle, but the area is right, just wrote it down wrong.

    So, yeah, there is lots of space on the side of the subs facing up, which is prefered, but not much space... unless I start the port close to the sub, and use an angle peice to run it to the sides...

    Or it can go on the face, on the left side of the above pic facing forward...

    Or whatever else anyone ccan think of... im looking on tuning 28-30hz or so
