In each crossover region, which spans approximately one octave, the sound from two different drivers must be added together. This simple fact creates problems in most speakers, because the phase must be matched, not just on axis, but also off axis in order to create a large "sweet spot" for the listener. Most speaker's drivers are only optimized on-axis, using measurements from a microphone placed at a single point in front of the speaker. This produces a horizontal zone in which the sound is optimized; however there may be drastic differences in sound quality along the vertical axis-meaning there may be a loss of sound quality if you stand up, sit, or otherwise move out of the optimized zone.
Induction Dynamics® eliminates phase differences with respect to height through our Wide Angle™ phase alignment technology. Because our patented circuitry provides additional variables that can help control phase, Wide Angle™ finds the one optimization solution that produces a flat frequency response along the vertical axis, when the microphone (or listener's ear) is moved up and down vertically. This means you experience true audio perfection whether you're standing, sitting, or lying down.
Most conventional speaker designs have a small and horizontally narrow "sweet spot" caused by inaccurate phase matching of the drivers. The best quality sound can be heard only within a very confined area. Outside of this area the sound quality can drastically decrease, becoming muddy or indistinct.
Patented Wide Angle. Phase Alignment circuitry provides precise phase matching of the drivers, noticably expanding the "sweet spot" both horizontally and vertically. Listeners are immersed in a large sound field and enjoy clear, undistorted sound regardless of their position relative to the speakers.
