Crossover frequencies are inherently problematic because sound from two very different drivers must be added together harmoniously, on and off axis. Typical crossovers are optimized on-axis, but allow phase mis-alignment in the vertical off-axis response. Vertical phase mis-alignment results in a loss of sound quality when standing up or reclining.
The patented Wide Angle® Technology in the unique S4X™ crossover has the capability to completely align phase between drivers. By utilizing steep S4X slopes and Wide Angle Technology, the crossover limits driver interaction and optimizes phase in the off-axis region, generously widening the listening “sweet spot.” Experience consistent audio perfection – regardless of whether you’re sitting, lying down, or moving around the room.
