Loudspeaker system design and modelling

CE Electro-Acoustics provides unique loudspeaker design solutions for custom installation or production. From headphones to hi-end, full-range or multiway loudspeaker and monitor designs, passive or active.

Shown on the left is a lumped element simulation example using AKABAK of an actively driven 3-way loudspeaker system.

Leveraging COMSOL Multiphysics for fully coupled electro-acoustic and structural-mechanical modelling ensures exceptional accuracy, streamlines design development, and underpins the assessment and optimisation of design improvements.

Advanced active designs can also be realised using onboard DSP, providing a greater level of design flexibility, resulting in 'complete control' and improved sound quality and protection of the loudspeaker.

Benefits of digital active designs can include:

• Custom bass transfer function (minimising enclosure volume and form factor).
• Limiters.
• Pre-set equalisation - for various room boundary conditions.
• Time alignment / phase correction - to optimise driver integration.
• Thermal monitoring and protection - for amplifiers and drive units.
