Phantom's elegant curves are guided by acoustics over design. Inspired by Harry Ferdinand Olson's pulsating sphere principle, Phantom's ACE, or Active Cospherical Engine, radically optimizes the way sound waves form and travel. Instead of projecting in the classic 180 arc-like traditional box speakers, Phantom achieves a 360 sound stage, emitting evenly and in all directions for perfectly balanced sound and zero surface diffraction. Whatever the listening angle.
