YN-ERA Description The YN-ERA stand was made to compliment the beautiful simplicity of the speakers. Resting securely on top of a thin plate, nothing is taken away from the design and lines of the speaker. Unlike other companies, these stands were left unbranded to preserve clean aesthetics. The details and proportions of the stand were chosen to make the speaker the center of attention rather than the stand. Rubber feet were added to reduce vibrations to hardwood and tile floors in order to prevent any extra noise. The built in cable management allows wires to be hidden inside the channel and pass under the base plate.
