Preparation
The use of subwoofers with built-in amplifiers, such as the Yamaha Active Servo Processing Subwoofer System, is effective not only for
reinforcing bass frequencies from any or all channels, but also for reproducing the high fidelity sound of the LFE (low-frequency effect)
channel included in digital audio signals. Turn it slightly toward the center of the room to reduce wall reflections.
You can use one or two subwoofers and select various positions of the subwoofers.
