    Box Help!

    If anyone could chime in about my box to see if its good or not...would be appreciated. internal net volume is 2.163 the port is a slot port and when it comes into the equation my volume turns into 1.938...as to why it gets lower im not sure. The port measures as follows W=13.5" H=2.5" D=11.5" Comes out to a volume of 388.125 Inches 3 seems weird???? What would this box be tuned to????? Help please guys.

    '

    The 388.125 cubic inches is the volume your port takes up within the enclosure, it should not be accounted for for the internal net volume. This is why it is saying 1.938. That is the 2.163 cubic feet minus the 388.125 cubic inches (aka .22 cubic feet).

    Re: Box Help!

    1.943 would be my box volume then. Thanks. Its a bit bigger than recommended size from Alpine 1.4 or 1.8 but close to 1.8. Just one more thing i cant figure out my port...i got the measurements but cant figure out what it would be tuned to or if its even close to being the right size. Its a custom made box which had the type x in it when i got it....box is really thick 1" and its made very very well just not sure it he did the port right or not. Doesn't sound as loud as it should.

    Noobs ITT. Anyway, 1.9 cubes is pretty small for a 12" Type X. I know what the specs say but They say 1.75 max. for the Type R and I always thought about 2.5 cubes was good. That X should be bangin' regardless....

    You got it... Impedance is kind of a tough thing to understand at first till you start looking at wiring diagrams and shit. When are your new subs coming btw? Or have they come?
