    This is the best wireless speaker developed by ub+. We have spent over
    a year putting our passion and effort to create the next generation of
    phenomenal wireless audio products.


    The goal in creating Alphorn by  ub+ was to have a beautifully crafted,
    state-of-the-art design while looking, feeling and most importantly,
    sounding spectacular.


    The good balance and symmetrical position of each speaker harmonizes the
    amplitude of the sound. They also greatly reduce sound distortion with
    less unwanted vibration from the cabinet. Through this synchronized
    reflection like a mirror effect through the single resonant channel,
    good sound quality is rendered. The bass is boosted in power and the
    sound is synchronized.

    Four speakers in a symmetrical position, balancing the pressure created
    by the speakers to harmonize the amplitude of sound.
