Audio Perfection Realized
™
Wide Angle™ Phase Alignment
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 speakers’ 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.
Conventional Speaker
System
Wide Angle™ Phase
Alignment
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, noticeably 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.
