    Anyone ever calculate the exact displacement of a full length 6'' PSP AeroPort?

    I am about to design a box 2 15'' RE HCs and would like to get to 8 cubes, 30hz, after displacements using two full length 6'' PSP AeroPorts but I am having trouble calculating displacement.

    Anyone ever run a calc for this or have any guidance?

    Help will be very much appreciated.

    Thanks,

    Kevin

No. In the end, the answer is, always has been, and can only be... heat kills speakers. BUT, clipping increases heat generation, sometimes by a drastic amount. So to start a thread simply to state that clipping does not hurt speakers is, again, a half-truth at best.

    I believe he's asking for the volume of displace of the actual port.

    r2 x pi x length / 1728 = cf

    That isn't exact displacement. You have to take the integral of the curve and rotate it around the z axis to get the precise displacement.

    I have the exact number but I misplace it somewhere. It's been 3 years since I've designed something with it.

    Re: Anyone ever calculate the exact displacement of a full length 6'' PSP AeroPort?

    Yea, the displacement of the aero as if it were a normal, round port would be close enough because it'd be such a small amount off on airspace if you really wanted to factor in the flared portion
