Defines the layered film construction of this two-ply head.

Independent shopping perspective
Designed for a 20-inch bass drum, the Emperor SMT Ebony pairs two 7.5-mil ebony film plies with a 5-mil clear film. Its externally mounted Sub Muff'l profile uses free-floating acoustic foam to manage overtones while retaining full tonal character. That produces clear attack, strong low-frequency weight, and controlled sustain over a wide tuning range. The controlled, balanced response is intended for live or recording work where bass-drum clarity matters alongside solid low-end depth.
