Evans coated EC2 series features two plies of 7mil film with optimized attack, tone, length of sustain and ease of tuning for each size head. The Sound Shaping Technology (SST) Edge Control ring mounted on the underside delivers an extremely well balanced and pre-EQ'd sound across the full kit by varying the size of the ring for each different head size.
Evans Level 360 technology enhances the playing surface of the drumhead, extending 360 degrees around the drum. The collar design ensures even contact with the drum shell's critical bearing edge, resulting in easy tuning, increased pitch range, and high-quality sound. This technology eliminates the age-old problem of synthetic drumheads not fitting the drum shell without applying force.
