Subwoofers
A Must for Home Theatre
Yamaha subwoofers use sophisticated technologies such as QD-Bass (Quatre Dispersion Bass, down-firing drivers that radiate the sound in four directions) and Advanced
YST (Yamaha Active Servo Technology) to ensure the highest levels of sound pressure and overall performance.
