Claim 13:
14. A method for generating an enhanced vertically enveloped listening experience for a listener at a listening position 24 in a room, comprising:
providing a multi-channel single enclosure Height-Channel enabled soundbar loudspeaker system comprising an elongated enclosure, a Height-Channel direct signal cancellation loudspeaker driver, and a Height-Channel speaker driver or multi-driver array, the elongated enclosure having a front baffle surface, a too wall surface, and a left sidewall, the front baffle surface terminating along an upper edge thereof with the top wall surface, the Height-Channel direct signal cancellation loudspeaker driver mounted at the front baffle surface, and the Height-Channel speaker driver or multi-driver array aimed upwardly from the top wall surface, positioned proximate to the left sidewall, and having an acoustic center spaced from the Height-Channel direct signal cancellation loudspeaker driver by a distance DL-AC in a range of 2 to 8 inches;
receiving, in the single enclosure Height-Channel enabled soundbar loudspeaker system, a Height-Channel signal, and generating a phase inverted Height-Channel signal in response thereto; and
driving the Height-Channel direct signal cancellation loudspeaker driver with a direct cancellation drive signal generated in response to the phase inverted Height-Channel signal, thereby reducing audible adverse effects of direct sound at the listening position.
