Improves audio quality by absorbing excess vibration that would degrade audio performance.
Performance Dampers absorb excess vibration from the chassis
Better sound volume from speaker
Speaker sound tone changed
Car audio sound quality improved
We played music on the car audio system with the engine stopped (in accessory mode), and measured the sound. (Test Vehicle: Luxury sedan)
Taking the average of the graph as it peaks and troughs, we found that car audio with Performance Dampers was 3 dB louder than without Performance Dampers.
Example sonograms (A characteristics, 8,192 lines, O/L 50%) With Performance Dampers, the green part mainly increases inside the white frame. It seems that Performance Dampers absorb excess vibration, causing the speakers to exhibit performance as intended, and uncover hidden tone that could never be heard before.
*Data based on Yamaha Motor’s evaluations
*It may not be possible to obtain sufficient benefits, depending on the driving environment, including road surface conditions and vehicle speed.
*Individual differences exist in how benefits are felt.
