From Mapex:

Dry and focused, crunchy and articulate, the all-aluminum Mapex Black Panther Atomizer Snare covers a ton of ground in a performance setting. Just like some of our favorite snares of all time, the Atomizer formula begins with a beaded shell of 2.0mm-thick aluminum — one of the most versatile shell materials ever discovered. Only in this case, the Atomizer's shell is slightly undersized to allow full freedom of movement between the heads, hoops, and shell. This creates a dynamic response in the hands of unearths a wide swath of tones for any adventurous tuner or drum tech. Tabletop tight or lax and loose, whatever tension you prefer, the Atomizer gives backs every ounce of a performance you pour into it. Flanged Sonic Saver hoops on rolled metal SONIClear bearing edges maximize the Atomizer's tone, warmth, and tuning range. And with its extra-deep/extra-wide snare beds and cylinder-drive dual-adjustment throw off, the Mapex Black Panther Atomizer aluminum snare drum can be dialed in for precision sensitivity.
