Get help for the Speaker Box Designer Determine the Dimensions of your Speaker Box based on the Calculated Volume Determine if your Driver works best in a Sealed or Ported Enclosure Calculate the Displacement Volume for Your Driver Read the Speaker Box Design Tutorial × Oct 07, 2012 · Vas - Suspension compliance. This number represents the "volume of air" that provides the same "spring" force as the suspension system on the subwoofer. What it means to you, is that a smaller Vas makes for smaller enclosures. What it also means, is that a smaller Vas makes for lower efficiency, and a higher system resonance as well. Mms ...

Subwoofer enclosure comparison calculator. Compare sealed, ported, bandpass, closed and vented boxes. Solve for box volume, frequency curve and port or vent length given Thiele Small specification.

Nov 17, 2010 · Re: Vas vs Box Volume The basic calculations are straightforward for a sealed box, but for a ported box, it gets more complicated. In either case, there are several freeware programs (as others have noted) that do the calculations for you, and provide a graphic simulation as well. Get help for the Speaker Box Designer Determine the Dimensions of your Speaker Box based on the Calculated Volume Determine if your Driver works best in a Sealed or Ported Enclosure Calculate the Displacement Volume for Your Driver Read the Speaker Box Design Tutorial × A common use of Thiele/Small parameters is in designing PA system and hi-fi speaker enclosures; the TSP calculations indicate to the speaker design professionals how large a speaker cabinet will need to be and how large and long the bass reflex port (if it is used) should be.

Online Loudspeaker Enclosure Calculation. On this page you are able to calculate a speaker enclosure with Thiele/Small parameter. The colors of the curves in the diagrams for frequency response, step response, group delay and voice-coil impedance have the following meaning: Vas = Equivalent air volume of driver suspension stiffness. Vas is used to calculate the size of the rear volume or backspace of the IB. In normal loudspeaker and subwoofer terms we'd call this back space the enclosure. The same holds true for IBs. IBs just use huge volumes for their enclosures.

All of the JL Audio recommendations for enclosure size are given as net internal volumes. If you are designing and enclosure based on these figures, you will need to take the displacement of speakers, ports, dividers, braces and any other object that occupies space into account by adding their combined displacements to the net volume figure.

May 14, 2007 · Vas is tricky to measure because air pressure changes relative to humidity and temperature. A precisely controlled lab environment is essential. Basically, Vas shows how much spring the speaker has relative to its surface area.

In either case, there are several freeware programs (as others have noted) that do the calculations for you, and provide a graphic simulation as well. Vas: Vas is the volume of air that has the same compliance as the speaker's suspension. Stiff speakers have lower Vas and tend to use small enclosures. Speakers with loose suspension have a higher Vas and use larger enclosures. Qes: Qes is the electrical Q of the speaker and only takes the electrical properties into consideration. Qms:

These specs can be measured (Vas, Qms, Qes, F3), but you need the equipment to do this. ... and it was a T-S ... Below is my new calculator for 2, 3 or 4 speakers wired in parallel. Simply type the impedance of each speaker into the white boxes (or use the drop-down values). Use N/A for unused speakers in this calculator. The total impedance will be calculated for the entered speakers. Also for each speaker is a calculated percentage.
