stute.x1D Designer

Create high end loudspeaker systems in only 5 steps.

1. Speaker driver

Powerful database with filter function

Select the speakers for the project from the database. Filters (such as manufacturer or category) or the parameter search (Vas, Qts,...) help to find the best match.

Copy & paste is no longer necessary: Details on the design and calculation, such as Vas or the installation dimensions, are automatically available in the further steps.

Your favourite is not in the database? Simply add more speaker drivers. If necessary, supplement the entry with a link to the PDF data sheet, the measurement file or a web page, e.g. from the manufacturer.

2. Driver enclosure

With automatic takeover of the driver parameter

The selected drivers from the database, including all parameters, are transferred to the volume calculation with a click. There is no need to enter Vas etc. After that you select a type of enclosure and start the calculation. Via simulation you get important insights into the interaction of enclosure and loudspeaker. 

Enclosure types: Sealed, Ported, Passive System, Transmission Line

Verification: The simulation shows the expected results, like impulse response or diaphragm stroke, before you order and assemble the enclosure. Perfect!

Import a measurement: Via a click import the measurement from the PC Audio Analyzer stute.x1A or an ASCII file and check the simulation result.

3. Audio filter

Easy via wizard

The crossover is elementary for the sound. It divides the music among the individual loudspeakers. stute.x1D makes the calculation and design very simple. This also applies to the correction of filter errors due to the complex loudspeaker impedance. The simulation shows the results and thus prevents expensive wrong purchases of crossover components. 

Does your dealer offer a capacitor with 5.25uF? The "REALizer" function replaces mathematically calculated components with commercially available parts. Simulate, check and correct the influence on the deviations!

stute.x1D also takes complex impedance curves into account for optimal sound results.


The component database stores commercially available components for audio crossover and cabinet construction (such as MDF), including their prices. 


Via web link you have quick access to the component data sheet or the web page of your preferred supplier.

4. Enclosure design

With bill of material output

The enclosure design wizard takes over all the data, like volume size and driver dimension, from the previous steps. In no time at all, you will receive a first enclosure design in 2D CAD view.  

No manual transfer: Automatic transfer of the loudspeaker driver dimensions and cabinet volume from the previous calculation steps. 


Fine adjustment: Then adjust the enclosure dimensions and the position of the drivers to your ideas. Finally, output a parts list and the drawing for building the enclosure.

5. Design Review

Hardware cost and more...

The complete design at a glance, incl. what's the price. The project map collects all the information about the design and calculates the material costs from speakers, components of the crossover and cabinet material....

All design details are just a click away from here. Even the measurement of the finished box can be saved here.


Note: Not in Basic version included.

Sound improvement / Room EQ

Flat the frequency response of the loudspeaker system via equalizer (EQ) or Audio DSP settings. stute.x1D calculates the setup.

Save costs via audio filter pre-check by Audio DSP

Save money and time with the acoustical pre-check of your audio filter design via the Behringer DCX2496 Audio DSP.


Transfer via a click the passive audio filter design into the Audio-DSP and make first test hearings. Adjust the audio filter design until you are fine with the sound. Order finally the passive filter components.
