To elaborate on the technical aspects, the frequency contour graph shows frequency in relation to SPL. L-Acoustics sonic signature, the frequency contour, boasts a wide-ranging and solid bass as well as perfect spectral linearity and stability (flatness) above 1 kHZ which brings a realistic foundation to the musical message independently of genre or stylistic content, giving an impression of volume and space, even in smaller rooms.
The shape of this curve is not a measurement of something that is left to chance. It is voluntary by design. L-Acoustics frequency contour results from research and application that combines objective data points, field observation, and repeatability with perceptual and creative design choices. Our signature is our identity, albeit a transparent and invisible one. It is how we can best support sound professionals in delivering musical creations that remain truthful to the original and in which listeners hear the musicality and the message, not the sound system.
To improve intelligibility for the audience, L-Acoustics deploys technologies to optimize the level of the pure direct sound coming from the sound system vs the reverberation of the room, while ensuring uniformity of sound signature for the entire coverage area. These technologies are part of the DNA of our products and reinforce our signature with the sensation of realism and proximity. The listener has the impression of hearing an instrument or voice up close, when in fact that same impression can be felt over a wide area.
Two technologies contribute substantially to L-Acoustics signature: Wavefront Sculpture Technology (WST) and Concentric Driver Technology (CDT).
The first, Wavefront Sculpture Technology, has made L-Acoustics the benchmark for professional sound ranging from intimate theaters to stadiums to massive outdoor festivals. WST focuses sound like a laser and makes it possible to carry a clean and intelligible message, giving an impression of proximity to the sound source even far away from it. WST is incorporated in the Tahiti, Tonga, and Ibiza Archipel sound systems.
The second technology, Concentric Driver Technology (CDT), adapted to listening over shorter distances, positions the transducers in a concentric formation, enhancing the realism of an instrument or voice. This does full justice to the fact that the sound of a voice is emitted from a specific point, and not from separate transducers which betray the integrity of the signal. At L-Acoustics we often say, “The best sound comes from one source.” CDT, present in our Fiji and Hawaii sound systems, adapts perfectly to smaller spaces.
