To prevent unwanted cabinet vibration, Yamaha developed an internal structure called VCCS (Vibration Control Cabinet Structure) that uses strategically placed pieces of a composite material providing excellent vibration isolation performance. In addition, three legs provide additional shock absorption, considerably enhancing sound quality.
The speaker units are a 12 cm (4-3/4") cone woofer and a 3 cm (1-1/8") soft dome tweeter. The woofer is an A-PMD (Advanced Polymer-injected Mica Diaphragm) unit created by downsizing and performing specialised tuning of a woofer used in Yamaha’s high-end speakers of “Soavo” line. It is a high specification speaker using the white cone, the symbol of Yamaha high sound quality.
