Advanced Design Take another look at Profile's shape, this time looking down at the top of the speaker. Note the similarity in shape to an egg, Focal dubs this an Omega structure. Aesthetically pleasing as it is, the contours of the Omega cabinet offer tremendous rigidity; eliminating midrange coloration and parasitic resonance at lower frequencies. Another benefit is the lack of parallel walls, which minimizes a form of distortion called aliasing. In a flat box, the back-wave from the woofer rebounds off the rear panel and strikes the driver within 1ms, distorting the pistonic motion of the driver. In the Omega cabinet, energy expands into the cabinet, then bounces around on the various rear walls and internal braces, taking a much longer path and is effectively dispersed within the loudspeaker. This is what gives Profile such clear, rich and defined midrange presence, highly accurate imaging and unparalleled dynamic range. Aluminum Magnesium Tweeter (Al/Mg) Focal is rightly proud of their Al/Mg alloy tweeter which combines the tensile strength of Aluminum with the feather weight of Magnesium. Magnesium damps the inherent high frequency resonance of Aluminum without adding significant mass, thus creating a design which is smooth and extended well past the range of human hearing. The tweeter is held rock-still by a massive and inert piece of formed Zamak (a Zinc, Aluminum, Magnesium and Copper alloy) inserted into the top of the cabinet. The Al/Mg tweeter doesn't sound like any metal tweeter you've ever heard, offering superb extension and resolution without harshness or brightness. Optimum Phase Crossover A crossover is a circuit within the speaker that splits frequencies amongst the drivers, ensuring bass doesn't go to the tweeter and treble doesn't get into a bass driver. Even though Focal builds every driver that goes in their speakers and can customize them however they want, there's no getting around the need f
