Concept & Cost
Loudspeaker enclosure
Audio filter design
New version

stute.x1D, the All-In-One solution for your loudspeaker box project:  Loudspeaker enclosure calculation, simulation and design. Audio filter design and simulation with replacement off “calculated” components with real existing. Two powerful databases (loudspeaker & components) with web links and filter functions. Auto-EQ calculation to correct the frequncy response plus transfer to a digital audio processor. And finally a project summary which collect all design details and calculates the material cost.

Module “Project view”

  • Summary about your loudspeaker box design
  • Easy jump into the details, like audio filter, loudspeaker, EQ settings or enclosure
  • File link to a loudspeaker box measurement 
  • Overall cost calculation
  • Project description input
  • Storage and print of the project 

Function "Audio filter transfer to DCX2496" 

  • Save money and check acoustical your audio filter design before you order expensive passive filter components
  • Design your passive audio filter with stute.x1D
  • Tranfer the audio filter per button click into the Behringer DCX2496 digital audio processor (software DCX.Server needed)
  • If needed, re-design and repeat the acoustic checks
  • Store the filter setup as a stute.x1D project 
  • Function part of the module "Project view"
  • See example setup below


Module “Speaker database”

  • Comfortable search via loudspeaker type, manufacturer or T-S parameter
  • Very detailed description to each loudspeaker
  • Automatic recommendation "Sealed" and "Bass reflex"
  • Transfer of the T-S specifications into other software modules
  • Easy adding of new speakers (Import)
  • Web link for each loudspeaker (e.g. to the web shop of your dealer)
  • PDF file link for each loudspeaker (e.g. to the manufacturer datasheet)
  • File link to a loudspeaker measurement (e.g. from Audio Analyzer stute.x1A) 
  • Loudspeaker import function (e.g. free speaker files in the download area)
  • Print a datasheet
  • ...

Module “Audio crossover calculator”

  • Fast audio filter design via the filter wizard: filter, RC/RLC, level divider (calculation & schematic) 
  • Near to the reality. Replace "calculated" components with real parts from the material database. Simulate the influence!
  • Simulation of the filter frequency response or loudspeaker Z impedance diagram
  • Sum frequency response simulation for a 2-5 way loudspeaker box
  • Frequency response import from Audio Analyzer stute.x1A
  • Filter frequncy response simulation includes the DC resistor from an inductance
  • Design and verify impedance EQ circuits (RC/RLC) and level divider
  • Cost calculation and bill of material output
  • Schematic editor 

Module EQ calculation

  • Automatic calculation of the Equalizer (EQ) settings to get a flat frequency response of your loudspeaker box
  • Frequency response import from Audio Analyzer stute.x1A
  • Visual EQ adjustment (tag the affected range in the XY screen)
  • Simulation shows expected frequency response with EQ correction
  • Manual adjustment of each EQ
  • Full automatic transfer of the EQ settings to the Behringer DCX2496 digital processor (software DCX.Server needed)
  • Alternative manual input of the displayed EQ settings into other digital processor systems
  • See example setup below

Module “Enclosure calculator”

  • Calculate loudspeaker cabinet types in seconds: Sealed, Vented, Radiator, Transmission Line
  • T-S parameter transfer from the loudspeaker database or manual input
  • Check via simulation the design “Frequency response”, “Cone excursion”, "Impulse response", "Air speed port" (excepted Transmission Line)
  • Frequency response import from Audio Analyzer stute.x1A (overlay with the simulation)
  • Loudspeaker Qts re-adjustment via the DC resistor in series  to the loudspeaker (e.g. via inductance DC resistor)
  • Print output

Module “Enclosure designer”

  • Fast design of a loudspeaker box cabinet
  • Easy takeover of chassis dimension (like inner & outer diameter) transfer from the speaker database
  • Cabniet wizard
  • 2D loudspeaker cabinet view plus dimensions
  • Bill of material output
  • Cost calculation (material from the componet database)
  • Simple 3D view incl. rotation
  • Print output

Module “Component database”

  • Second database with audio crossover components (R,L,C,...) and loudspeaker cabniet material
  • Inductance L with DC resistor value (input for the simulation)
  • Search according to component type or value (inductance air core in the range 1mH to 3mH)
  • Web link for each component/material  (e.g. to the web shop of your distributor)
  • Easy adding of new material
  • ....
