Ole Wolff offers extremely strong acoustic R&D support for both full systems and individual drivers.
Our global R&D team includes Danish engineers with more than 25 years of experience in designing world class premium drivers and audio systems.
The engineers at Ole Wolff will work closely with your team to achieve optimal audio performance. We can tailor everything to your requirements including customize the driver to generate your own unique drivers.
Utilizing tools such as Klippel, Sound check and Comsol 3D simulations we are able to meet your exact performance requirements.
Project success requires good management
Good management requires good communication
Good communication requires great local support
With great local support we make sure we don’t assume anything. If we have a question we will ask.
Quality management is key! QA process is controlled from product development through shipment
Each shipped product meets all environmental, reliability and life testing
All parts tested with Soundcheck
Highly automated production setup
