Good sound effect and high power. Songchuan International Audio uses a 3-way subwoofer + 3-way crossover design. The bass part uses a 12-inch large-diameter woofer to reproduce a deep and powerful low-frequency effect. The mids and highs adopt Panasonic's patented coherent source sensor technology, which produces sound field reproduction and a strong sense of layering. The maximum power of Songchuan International Audio is 320W, using AD and DA digital conversion technology, with a signal-to-noise ratio as high as 113dB.
