Tuning My Box To Hit Lower! - How To Tune a Ported Subwoofer Box/Enclosure Rectangle sealed enclosure volume calculator.Ĭircle port to slotted port calculator. Speaker wiring :Parallel, Series, Series-Parallel. Then under square vent, type in the height and width of the port you wish to use. If you are using a slotted port, select square under port type, then answer yes under are you using a slotted port. 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. 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.

Wiring diagrams Detailed wiring diagrams. See the Damping Treatments page for some more information about damping.Information Labs. Frequency peaks in a sonosub are not as strong because the reflecting surface of the top endcap is fairly small.Īdding some closed-cell foam damping material to the endcaps is good practice. In a normal box, a driver-to-rear-wall resonance that occurs in the working frequency range, can be troublesome, adding a peak of up to 6dB. Making a flare for the port intake is described in the donut ring walk-through. See the section on port flares for help with calculating flare requirements Most sono builders use a roundover bit in the router to flare the port exit in the top endcap. Flared ports allow a higher airspeed before audible turbulence occurs. The same clearance is required between the top endcap and top cover plate when used.

The distance between the port intake and the back of the driver must be no smaller than the internal diameter of the unflared portion of the port. If you have a driver with a large Xmax, you would build a bit of leeway in by dividing by 3 instead of 4 Sonosub. Subwoofer Box Design Comparison Calculator

A Resonances Experiment was conducted to determine what type of resonance occurs between the driver and end wall.Īir movement generated by the driver shouldn't encounter any reduction in the CSA through which it has to flow. This check is simplified somewhat by basing it on the nominal diameter of the driver. The gap between the driver and the bottom plate should be such that the air leaving the driver doesn't encounter a cross-sectional area that is any smaller than the cone area. Several of the checks need some explanation Clearance between port intake and driver should equal to or larger than the port diameter Clearance between port exit and top cover when fitted should equal to or larger than the port diameter. When you return to the front screen, the known values will be shown in blue and any substitutions will be shown in red. The software will use the generic value based on the nominal diameter you select for the driver. If you don't know one of the values, just enter zero for it's value.
