    9515 ports?

    I am building a box for a 9515 getting 2800rms. It will be tuned to 38-40hz and the cuft will be between 4 and 5. Now my question is should i use a slot port or aero ports?

    If i use aero ports they will be flared 4" diameter ports. How many should i use?

    Re: 9515 ports?

    would there be any difference by ear between the aero ports and slot ports?

    no diff by ear. DD recommends 16^2 per cube, so just do a big slot port. I've built a few boxes for 9515's, 4.5cubes @ 35Hz and they hit hard and sound good in that enclosure.

    roughly each 4" aero gives 12.56"^2 of port area.

    12.56*5=62.8/16=3.925<-- not enough 4 cubes gross
    12.56*6=75.36/16=4.71<--- just about what he needs

    each 6" will give roughly 28.26"^2 of port area.

    28.26*2=56.52/16=3.5325<-- not enough for 4 gross
    28.26*3=84.78/16=5.29875<-- too much for 5 gross
