The prototypes and their tests

We create many scale prototypes that we test in order to verify the sound quality reproduced. This allows us to develop a detailed understanding of the speaker system's performance from an early stage.

Using a real-sized model, a multitude of tests is carried out in order to guarantee that the systems satisfy the specifications. The results of the tests are confronted with the demands, allowing us to refine and finalize the design.

Our tests are traditional but uncompromising, based upon:

• Impulse response
• Bandwidth
• Waterfall diagrams
• Directivity
• Harmonic and intermodulation distortion
• Acoustic and electric impedance
• Position of emission centres
• Shock absorption of structures
• Configuration tests
• Listening tests

Specific computer programs have been developed by our engineers in order to carry out the most intensive tests, which allow us to reach the utter result.

With diverse configurations and a variety of speaker systems, the measurements obtained bring to light certain singularities, useful for adjusting the design.
