1. A first playback device, comprising:
a first side-firing transducer configured to output sound in a first direction;
a first up-firing transducer configured to output sound in a second direction that is vertically angled with respect to the first direction;
one or more processors; and
data storage storing instructions that, when executed by the one or more processors, cause the first playback device to perform operations comprising:
receiving a first subset of channels of multichannel audio content including first vertical content having a first high-frequency portion and a first low-frequency portion; and
playing back, via at least the first side-firing transducer, the first low-frequency portion of the first vertical content in synchrony with playback, via a second playback device, of a second subset of channels of the multichannel audio content.
