The NRG Series is TRX' range of aggressive, heavy metal, high-frequency cybals. These bright cymbals add to the full spectrum of sounds that TRX offers. It helps drummers to add different kind of contrasts to their playing.
At the Winter NAMM 2014, TRX president David Levine demos the differences between the DRK, MDM, and NRG and explains how TRX has always been trying to create a spectrum - from the DRK Icons to the NRG series. So instead of relating each cymbal to a different style of music, the folks at TRX relate each model to a sound spectrum.
