    JL 12W3v2-D4.. volume for SQL?

    JL recommends 1.75 @ 30.3Hz. The port has less than 20 sq/in of port area.

    What do ya'll recommend for volume and port area? Ive whipped up a WINisd calculation of 2.5 cu/ft @ 35Hz, 25 sq/in of port area, and came out with a 4.1db gain.

    Im also on the brink of making an ABC box for it.

    I wouldn't relay too heavily on WinISD.

    With that being said, i would recommend ~2.0 cubes tuned to 32hz for a good mix of SPL and SQ. port area should be around 25 sq/in.


    lol.


    Winisd assumes the world is perfect. Try putting in 100g for the added mass on the cone. you can see a huge spike down low, but are you going to get that gain? nope. Win ISD doesn't know when the suspension can handle the extra mass or not, or when heavy power compression arrives, or any of that good stuff.

    of course you can always build many boxes and toy around with them.



    Hello GSteg it appears that you have not posted on our forums in several weeks, why not take a few moments to ask a question, help provide a solution or just engage in a conversation with another member in any one of our forums?
