Overview The Armory Series is the latest realization of the Mapex hybrid shell concept. A fusion of birch and maple delivers the ultimate tonal expression, and the SONIClear™ bearing edge allows the drumhead to sit flat, bringing out the best response by optimizing the relationship between head and shell. FEATURES The Birch/Maple/Birch 6Ply 7.2mm shell with the new SONIClear™ Bearing Edge allows for the direct transmission of sound, reduces unwanted frequencies and provides a strong fundamental pitch and an effortless tuning experience especially at lower tunings. This 6-piece shell pack includes 10"and 12" stand mounted rack toms, 14" and 16" floor toms, 14" snare drum and a 22"x20" kick. The SONIClear™; tom suspension and floor tom feet increase overall resonance by preserving vibration in the shell and keeping stress away from the tension rods, helping the heads stay in tune.
