Aluminum shell din yung acrolite...same spun aluminum shell (seamless) used on supraphonics, different hardware lang and finish.
Haven't tried the tama aluminum drum, pero I'm sure being both aluminum, minimal lang yung difference sa sound given that both drums have the same tuning, heads and size.
Generally, dry sounding ang aluminum. Medyo woody tone, pronounced mids na meron mid-pitched ring na nawawala agad. Sobrang controllable yung sound kaya madaming studio musicians preferred to for recording. Ok den for live unmic'd situations pero volume wise hindi kasing lakas ng steel snare drums
