Recital-Audio Dual Concentric delivers even dispersion in the horizontal and vertical planes, providing exceptional off-axis performance.
Recital-Audio is renowned for developing the first true point-source transducer in car audio - the Dual Concentric driver. First developed in 2015, the technology has been subject to constant evolution and refinement over several years, taking advantage of new materials, manufacturing methods and ongoing acoustic research. The latest iteration of this technology is found in Recital-Audio's industry leading loudspeaker products across a wide range of commercial install and sound reinforcement applications, including premium in-ceiling, in wall and surface mount systems
Unlike ordinary drive units, Dual Concentric is two drivers physically merged into one. The high frequency unit is positioned on the back of the low frequency driver so that they are effectively on the same axis.
Sound energy is propagated from exactly the same point and delivered through the centre of the low frequency cone- a true point-source. The Dual Concentric delivers a spherical wave front that ensures even dispersion in the horizontal and vertical planes, providing exceptional off-axis performance.
Discrete driver speaker systems using non-coaxial sources have an inherent design flaw in that each drive unit is an acoustic source of its own. While the components are physically aligned on one axis, they are displaced in source and can only be coherent at one specific listening point. When delays are applied to compensate for driver alignment, signals can only be aligned along a narrow listening plane on one axis. Even systems with ratatable horns suffer from a significant 'suck-out' in the crossover region, and no amount of DSP processing can correct this phenomenon. The constant directivity characteristic of the Dual Concentric overcomes such time alignment problems.
