Massive bass

Would you like your set of speakers to have a massive bass sound? Then, the YST-SW030 subwoofer is just for you. It uses a powerful 20cm speaker and a set of smart technologies to ensure dynamic output. Additionally it is magnetically shielded to minimise interference with home electronics.

Key features

  • A powerful 20cm driver for massive bass.
  • Shielding to minimise interference with surrounding electronics.
  • Advanced YST technology for high performance.
  • QD-Bass technology to minimise interference between the floor and driver.


Advanced YST

Advanced Yamaha Active Servo Technology (Advanced YST) creates a unique system in which the amplifier and the speaker cooperate as one unit. The result is the virtual interference of the speaker impedance and a perfectly linear motion. Due this technology, the speaker can also achieve higher volume levels and overall higher performance.

QD-Bass Technology

Quatre Dispersion Bass technology uses downward facing transducers with square, pyramid shaped reflective plates to radiate the sound four ways horizontally. The reflective plates neutralise any reaction caused by the floor surface and simultaneously reduce resonance between sound waves reflected from the floor and subwoofer.
