A speaker system is provided with a cabinet with a front face. At least one forward-firing driver is supported by the cabinet to project sound along a first axis that is generally perpendicular to the front face of the cabinet. At least one upward-firing driver is supported by the cabinet and arranged above the at least one forward-firing driver to project high frequency sound along a second axis that is angularly offset from the first axis at an acute splay angle. A controller is programmed to provide a mid-range frequency component of a front audio channel to the at least one forward-firing driver, and to provide a high frequency component of a top audio channel to the upward-firing driver.
