An Optimized Full-Bandwidth 20Hz-20kHz Digitally Controlled Co-Axial Source

In this paper, we address the design considerations of the first four-ways full-bandwidth co-axial loudspeaker system. Unlike conventional co-axial drivers, a special motor configuration has been considered in order to approach a real co-incident source. Practical constraints of moving mass element and cone shape will be shown with reference to the targeted sound radiation characteristics. Dedicated digital signal processing techniques has been implemented in order to optimize relevant parameters such as frequency response, directivity index and radiation patter of the system especially on drivers’ overlap bands. The optimization is obtained by a complex weighting of the crossover filter transfer functions. The optimal weights are obtained with a new routine using the gradient algorithm.
