Welcome to our projects page!

Here you will see...not that much. Privacy, integrity and the protection of your intellectual property are our highest concerns and of course everthing is covered with non-disclosure agreements (NDAs). In addition Dausend Acoustics is not meant to be in the foreground. We are acting in the background helping you reaching your goals, so we will not appear in public or for your costumers.

However, to help you to better understand what we do and what we can do you will find some example projects that happened or could have happend that way.

 

 

Outdoor Loudspeaker Series

For a well known pro audio brand we developed a passive loudspeakers series with small to midsize ranged models made out of plastic.

Mechanical Engineering:

  • The designer provided a surface model which we turned into a solid model
  • Construction of the cabinets including for example the grill, braces, assembly details, draft angles
  • The goal was a 90% detail level for tooling process, the last few percent should be done by the supplier

 

Prototyping:

  • All the models had been in house 3D printed,
  • Crossovers and cabinets had been assembled to be ready to use for acoustic approval at costumer site
  • Beside functional prototypes also various design prototypes had been printed

 

Acoustical Engineering:

  • Tuning the passive crossovers, taking also into account producibility, cost and performance
  • Documentation of possibilities to make the customer able to change for example the timbre of the sound
  • Power tests for specifying the dimensions of the parts including failure behaviour
  • Klippel laser tests to optimise the transducers
  • BEM simulation of the waveguides for the dome tweeter to achieve constant directivity

 

More projects will soon be shown here.
