What are the pros and cons of using the extended phase linearity?
Better phase match with two-way monitors, particularly significant in mixed system layout, such as in many immersive monitoring systems. This improves accuracy of imaging in mixed two and three-way monitor systems.
For stereo systems: improved stereo imaging focus and precision, enhanced off-axis performance and more stable Ultra Nearfield (UNF) imaging.
Using the extended phase linearity adds 3.7 ms more delay in the monitor. To understand the significance of this delay, consider that moving a loudspeaker away by 1 meter creates an additional delay of about 3 ms.
