What does sub box tuning mean.

Calculate a speaker box volume port length and other parameters without getting confused in formulas. F b a v 0 31 x f s 100 400 0 31 x 40 0 6507 x 40 26 028. The closer the notes are to the tuning frequency the greater the reinforcement the boom that people describe. S elect whether you are using a round or slotted port for you box design.

This calculator will determine what length port to use in your ported enclosure. Alex an enclosure designed for a 12 inch subwoofer will probably not work very well with a 15 inch sub. A subwoofer box of volume 400 m 3 requires the minimum air of 100 m 3. E nter the number of ports you are using the internal airspace of your box then tuning frequency you wish to use and then hit calculate button.

This will limit the tuning of the enclosure to a higher tuning frequency. We can provide you with comprehensive subwoofer box calculator for online creating a high performance subwoofer enclosure. Subwoofers are designed to reproduce low frequency bass tones so a low pass filter is very important. Most subwoofer amplifiers have a low pass filter which prevents higher frequencies from reaching your subs.

Ported boxes are tuned by their internal volume and port length and area so yours may not be very well tuned for bass. To tune a ported box to a low frequency you must use a larger enclosure with a larger and longer vent. Calculate the tuning frequency f b. But if the enclosure has enough depth and you can enlarge the cutout hole in the baffle you could probably get one in.

Given a 100 v 400 fs 40 hertz to find box enclosure tuning frequency f b solution. Resonance frequency of speaker is 40 hertz. In a smaller enclosure this gets very difficult to fit the port into the enclosure due to the limited volume of airspace you have to work with.
