    need help on enclosure!

    hi was wondering if anyone could help me find out roughly how many cubes my enclosure is internaly and what its tuned to. the box is 33"w 14.5"h and 26"deep. the port area opening is 6"w and 13"h so 78" of port. the box is single layer all around except the front which is double baffled and the box is for 2 12's. so with those dimensions can anyone tell me how many cubes my box is internally and what its tuned to? thx!

    need to know the length of the port as well

    the port is in the middle of the box and both ends go 17.5 deep.

    Re: need help on enclosure!

    Without knowing the thinkness of the wood and how it is assembled. My guess would be about 5 to 5.5 cu ft. And tuned in the high 30's (36-39Hz).

    That's my best estimate without running the numbers.
    Someone please correct me if I am wrong.

    Re: need help on enclosure!

    I'm getting a net volume of roughly 4.9 cubes tuned to around 42 hertz, depending on driver displacement.

    Re: need help on enclosure!

    Alpine should be able to tell you what the driver displacement of a 12" Type R is. Multiply that by 2 and you have total driver displacement. It will affect total internal (net) volume and tuning.

    Internal Volume = Net Volume

    Re: need help on enclosure!

    just crunched some numbers; depending on 3/4'' wood, i got about 4.6 cubes tuned to 43hZ using Apline's specs at .071cu per sub.
