What Does Sub Box Tuning Mean

Below the tuning frequency the sub s output drops off more dramatically than it does in a sealed box so the lower a box s tuning frequency is and most are in the 30s the deeper a sub in a ported box will comfortably play.

What does sub box tuning mean.

Most subwoofer amplifiers have a low pass filter which prevents higher frequencies from reaching your subs. Subwoofers are designed to reproduce low frequency bass tones so a low pass filter is very important. Given a 100 v 400 fs 40 hertz to find box enclosure tuning frequency f b solution. The closer the notes are to the tuning frequency the greater the reinforcement the boom that people describe.

Calculate a speaker box volume port length and other parameters without getting confused in formulas. To tune a ported box to a low frequency you must use a larger enclosure with a larger and longer vent.

S elect whether you are using a round or slotted port for you box design. Alex an enclosure designed for a 12 inch subwoofer will probably not work very well with a 15 inch sub. Ported boxes are tuned by their internal volume and port length and area so yours may not be very well tuned for bass. This will limit the tuning of the enclosure to a higher tuning frequency.

Build a ported box sealed box for your low frequency speaker. But if the enclosure has enough depth and you can enlarge the cutout hole in the baffle you could probably get one in. Calculate the tuning frequency f b.
