The body of the AluVibe Eterea snare drum is made from PMMA (Polymethyl Methacrylate) cast in a single piece (Seamless Cast Acrylic), a choice that ensures structural stability and a clean, linear sound.

1. Monobloc casting (Seamless Design) Unlike traditional acrylic bathtubs, which are made by bending and gluing a flat sheet, Eterea bathtubs are formed directly into a cylindrical shape through rotational molding. The absence of vertical joints eliminates any points of discontinuity, distributing the mechanical stress evenly along the entire circumference. A differenza dei fusti in acrilico tradizionali, ottenuti piegando e incollando una lastra piana, i fusti Eterea nascono direttamente in forma cilindrica tramite stampaggio rotazionale. L’assenza di giunzioni verticali elimina i punti di discontinuità, distribuendo uniformemente la tensione meccanica lungo tutta la circonferenza.

2. Thermal annealing: After solidification, the cylinder undergoes a controlled thermal annealing cycle. This step eliminates the internal molecular stresses accumulated during cooling, stabilizing the material over time and making it resistant to temperature changes and hardware stresses.

3. Integration of the AluVibe flange The solid nature of the monobloc allows for precise mechanical machining. The edge of the drum is specially machined to accommodate the aluminum flange that is a hallmark of AluVibe products, ensuring a precise, millimeter-accurate fit that optimizes the transmission of vibrations between the hardware and the drum.

4. Acoustic response The uniform density of cast PMMA allows sound waves to propagate evenly. The result is a snare drum with a clear sound, a defined attack, controlled low frequencies, and excellent overall volume, accompanied by a transparency that enhances the internal mechanics. 4.
