You may download this file and use UniBox freely for design of your personal loudspeakers as long as it is for non-commercial purposes only. I will not be held responsible for any bad sounding loudspeakers or any problems of any kind this file may cause you. It will import Design Data Base files version 1. Download Design Data Base with over drive units. The TS parameters are extracted from brochures or found on the Internet. Note, to lookup the TS parameters of your favorite unit is good.
To measure the parameters yourself is even better. Peerless data base ubase Bruce Slevinsky has compiled a design data base containing drivers.

As it has been impossible for Bruce to get the full set of TS parameters for all units he has calculated the missing parameters needed for UniBox using a technique described in his memorandum and corresponding Excel sheet.
The Bruce Slevinsky data base ubase Jan Fredriksson of the Thiele-Small Loudspeaker Database Web site maintains one of the largest databases for Thiele-Small parameters of your favorite loudspeaker units.
Furthermore, a host of other useful design parameters are listed. You can also submit new or your own TS data to help make the database even better. Excel 97 Many Excel 97 users reports that UniBox 3. Some have problems with a few features but usually this is cured when all Microsoft service releases are installed.
Users of the French version of Excel 97 have problems when opening UniBox, but Antoine Bonin found an easy work around. Go to the Windows regional parameter setting and select English instead of French. This has been verified by Christopher Pace with a good result too.

Drive unit efficiency calculations added. Export of all graphs using GIF image file format. Design Data Base format has not been changed.
The effect of this inductance model is now included in all graphs. Passive low pass crossover of up to 4. Port self resonance model added to the vented box design.
missing attachment from step 3
Driver piston range calculated and shown in mini-graphs. Imports Design Data Base file ver. Exports Design Data Base file ver. Calculation of the required power amplifier RMS voltage needed to produce the wanted nominal power.
A check box has been added for easy selection of whether the crossover circuit is to be included in the frequency response graphs. Calculation of the drive unit effective Qts now also includes the loss resistance of the crossover coils 4.
The effect of Rco1 and Rco2 now included in efficiency and effective Qts calculations. Minor enhancements and adjustments. Further improved online help windows. Corrected a bug in the impedance graph calculation of the high frequency inductance part when using multiple drive units. You can now import an active filter correction function and see the resulting frequency response, cone excursion, port air speed and much more. A typical design approach would be to simulate your box in UniBox and export the frequency response as a FRD file.
Export this correction as a FRD file and use the new import feature of UniBox to see the final results.

Graphs have been added to show the necessary power amplifier peak voltage and peak current for all box alignments. Now also extrapolates any high frequency curve if needed. The imported file is normalized to 0 dB at its maximum value. Suitable for general active subwoofer crossover filters.

If you would like to check your baffle diffraction, produce FRD files from a graphic frequency response or calculate a Linkwitz Transform circuit have a look at Paul Verdone's site with links to it all. This is a real good collection of free programs created by the FRD Consortium. You have been listening to some funky jazz.
Sponsored by: Charlie's Audio Pages. First release of Excel version with enhancements related to better Excel performance. Improved prediction of suggested port minimum diameter to avoid port noises.
