Speaker cabinets vibrate, degrading sound quality. Adding internal reinforcements haphazardly does no good. While the addition of conventional rubber or other damping materials can be effective, their shortcoming is that they affect all frequency bands, while the vibration only affects a narrow band.

To overcome this, the Yamaha speaker team developed an internal structure called VCCS – Vibration Control Cabinet Structure. This technology uses strategically placed pieces of a composite material, providing excellent vibration isolation performance. Their shapes, positions and angles were determined after a long process of experimentation.

The result is that unwanted cabinet vibration has been greatly reduced. The sound you hear is not negatively affected by the cabinet, putting these system speakers truly in a class of their own, with clear, powerful sound that will first surprise and then delight you.

The speakers use a large aluminum cone that provides extremely fast attack time (sound response) for clear and precise midrange and bass. The tweeter is a soft dome that conveys all the high range subtleties of the human voice. The port on the back assists in bass dispersion – examine this port and you’ll see that this is a high-grade speaker.
