1. A crossover circuit for use in a speaker system transmitting sound waves for a full-bandwidth, object-based audio content having height and direct components to be reflected off an upper surface of a listening environment, comprising:

  • an interface from a renderer to a speaker having a direct-firing driver within a cabinet and oriented to transmit sound along a horizontal axis substantially perpendicular to a front surface of the cabinet and an upward-firing driver oriented at an inclination angle of between 18 degrees to 22 degrees relative to the horizontal axis; and

    a separation circuit comprising a crossover stage having a low-pass section configured to transmit low frequency signals below a threshold frequency to the direct-firing driver, and a high-pass section configured to transmit high frequency signals above the threshold frequency to the upward-firing drive,
