    Icon32 Influence of external port volume

    Hi all

    If one extends a port/s outside of the enclosure does it influence the tuning frequency? For example if there's 20cm inside the enclosure and 60cm outside the enclosure will the tuning frequency be affected?

    What other outputs of the setup will be influenced by this practice?

    Re: Influence of external port volume

    you would calculate tuning same way you would for any enclosure only diffrence is that youll only substract the displacement of the port thats in the enclosure.
