Unopened, brand new item. Vibration-damping turntable mat for record players. For analog record enthusiasts! ■ Color: Black ■ Size: 4mm (thickness) x 291mm (φ) ■ Material: Non-rebound rubber (Haneight rubber) Many analog record enthusiasts are troubled by the deterioration of sound quality due to "vibration" and "resonance distortion." This product employs the special vibration-damping rubber "Haneight" to absorb these vibrations and resonance distortions. It effectively absorbs unwanted vibrations in the frequency bands crucial for music playback, further enhancing the ability to reproduce analog records with a rich musicality and a sense of realism. ■ Features ● "Haneight," a non-rebound rubber, has a significantly faster vibration damping time compared to natural rubber and other synthetic rubbers, quickly and effectively absorbing unwanted vibrations in the frequency bands important for music playback. ● Achieves vibration absorption performance far exceeding internal losses compared to natural rubber and other synthetic rubbers. ● Ideal friction coefficient for close integration of the record and turntable. ● Exhibits high vibration damping effects at room temperature, far surpassing other materials. ● Achieves excellent durability that can withstand years of use.
