What does sub box tuning mean.

This calculator will determine what length port to use in your ported enclosure. This will limit the tuning of the enclosure to a higher tuning frequency. Make a subwoofer enclosure plan. Subwoofers are designed to reproduce low frequency bass tones so a low pass filter is very important.

We can provide you with comprehensive subwoofer box calculator for online creating a high performance subwoofer enclosure. A subwoofer box of volume 400 m 3 requires the minimum air of 100 m 3. Build a ported box sealed box for your low frequency speaker. F b a v 0 31 x f s 100 400 0 31 x 40 0 6507 x 40 26 028.

Calculate a speaker box volume port length and other parameters without getting confused in formulas. Most subwoofer amplifiers have a low pass filter which prevents higher frequencies from reaching your subs. Alex an enclosure designed for a 12 inch subwoofer will probably not work very well with a 15 inch sub. 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.

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. Time to adjust the built in crossovers on the amplifiers in your system. Given a 100 v 400 fs 40 hertz to find box enclosure tuning frequency f b solution. 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.

But if the enclosure has enough depth and you can enlarge the cutout hole in the baffle you could probably get one in. To tune a ported box to a low frequency you must use a larger enclosure with a larger and longer vent. The closer the notes are to the tuning frequency the greater the reinforcement the boom that people describe.
