What does sub box tuning mean.

The closer the notes are to the tuning frequency the greater the reinforcement the boom that people describe. Most subwoofer amplifiers have a low pass filter which prevents higher frequencies from reaching your subs. But if the enclosure has enough depth and you can enlarge the cutout hole in the baffle you could probably get one in. 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.

Ported boxes are tuned by their internal volume and port length and area so yours may not be very well tuned for bass. 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. Alex an enclosure designed for a 12 inch subwoofer will probably not work very well with a 15 inch sub. 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. 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. Resonance frequency of speaker is 40 hertz. This calculator will determine what length port to use in your ported enclosure.

Calculate the tuning frequency f b. Time to adjust the built in crossovers on the amplifiers in your system. A subwoofer box of volume 400 m 3 requires the minimum air of 100 m 3. S elect whether you are using a round or slotted port for you box design.

Subwoofers are designed to reproduce low frequency bass tones so a low pass filter is very important. Build a ported box sealed box for your low frequency speaker. To tune a ported box to a low frequency you must use a larger enclosure with a larger and longer vent.
