Measurements

All our Measurements are done on KEMAR from G.R.A.S. Sound & Vibration. The Denmark based Manufacturer makes some of the most specialized Audio Measurement Instruments on the planet. 
KEMAR is equipped with its Anthropometric Pinnae.

All our supplied graphs are RAW. A mental compensation can be applied accordingly.  

Vertical Integration

This is an area where very few Manufacturers can proudly attest to. 

Kaldas Research is a Manufacturing company at heart and our core business is contract R&D and Manufacturing. 

Every product to bear that Kaldas badge will be in-house or else it doesn't deserve the name. 

We don't outsource. We Design and Manufacture in-house and always will in the future.
