    Aero Vs Slot Ports

    I searched around but can't find an answer.

    Would either one displace less if they were tuned to the same frequency. I am just curious because I am really short on space. I have to make the box an awkward shape just to get all I can out of the trunk. I dunno for some reason it just seems to me like the Aero would displace less.

    Thanks, Jon

    Re: Aero Vs Slot Ports

    With Aero's you can generally get away with less port area, and it is easy to make them external.

    Re: Aero Vs Slot Ports

    There isn't going to be any room in the trunk for external ports....so if its inside it doesn't matter?

    Re: Aero Vs Slot Ports

    Areo's are most commonly used because it is easy to take them out and modify the length to change the tuning of your enclosure. Other than that, there really isn't much upside to using them vs. slot ports. Both displace (assuming aero's are flared, which they should be) approximately the same volume. Any difference in displacement is typically neglible.

    Re: Aero Vs Slot Ports

    a aero for my box in a 5.2net box and is for 2 12's l7's is aeroported one 6" at 34hz and only takes up .14cuft so it makes a huge difference in amount of airspace not taken up from port
    and aeros will be louder some say and less port noise and also with a port u can change the tuning freq

    Re: Aero Vs Slot Ports

    You can usually use less port area if you are using aeroports, which in theory will already displace less air.

    Even with that, an aeroport will displace less air than a similarly sized slot port. Aeroports are thin walled PVC while a slot port will be made out of 3/4" wood.

    So you save mucho airspace going with aeros.

    Re: Aero Vs Slot Ports

    unless you do alotta work with a router the aeroports will give you better airflow which mean less port noise and higher spl. another benefit of aeroport is simplicity . aeroports= build a sealed box and slide in the aeroport. slot ports box are more tricky to design. last aeroport will save you alot in weight . that said i'm not going back to slot ports.

    I've never actually calculated it, but wouldn't the flare on both ends of the aero come close to matching the displacement added by the wall of MDF? (obviously this becomes neglible when you have multiple bends in the port)

    No.

    The flare is nowhere near the same displacement as a piece of MDF.

    Indeed.

    psp says the flare is actually negligble in calculating displacement.

    Autocad confirms

    I just assumed (visually) it would have some sort of effect. Wierd.

    Re: Aero Vs Slot Ports

    The accoustical length of a slot port is longer then a regular port or an aero port. That means for a given tuning frequency with the same amount of port area the slot port will be shorter and take up less volume inside the box.

    If you are concearned about the volume the extra slab of wood will take up, use some 1/4" hardwood ply
