Specific Job Duties:

• The design of loudspeaker systems from concept to manufacture including but not limited to:
o The specification and optimisation of transducers
o The design of loudspeaker enclosures, phase-plugs and horns using modelling software and physical prototyping
o Passive crossover design using software tools and practical prototyping
o Active crossover design, equalisation and limiter settings
o Benchmarking against existing and competitor product
o Building and evaluation of physical prototypes using measurements and critical listening in order to iterate and optimise deigns to meet or exceed the required performance
o Completion of power tests and design iteration as required to ensure product longevity


• Degree in Acoustical Engineering, Electroacoustics or other related subjects.

Knowledge, Skills, and Abilities:

• Good understanding of acoustic devices including application of tools for measurement and analysis.
• Horn design. A good understanding of acoustic efficiency and directivity and the theory and practical application of acoustic principles to achieve a desired performance.
