Overview: The Sonos Sub is a wireless powered subwoofer, designed to
add deep bass (down to 25 Hz) to your Sonos listening experience. The Sub works
with any amplified Sonos player, including the
Connect:Amp (ZonePlayer ZP120), or ZP100. It does not work with un-amplified Sonos
players, such as the Connect (ZP90) or the ZP80.
Design: The Sonos Sub features two force-canceling speakers (3" x 6" race-track shaped drivers) positioned
face-to-face to provide deep, rich bass with no resonance from the cabinet. The
speakers are powered by two Class-D digital amplifiers, perfectly tuned to match
the speakers. The speakers are mounted into a unique cabinet that features an
acoustic slot and dual acoustic ports that encircle the enclosure to enhance the
Placement: Out of the box, the Sonos Sub is designed to stand upright
on the integrated rubber feet. You can also lay the sub horizontally on its
side, if desired. Four self-adhesive felt feet are provided, if you choose to
mount the Sub on its side. A guide for placing the felt feet on the Sub is
Set-up: The Sonus Sub can be associated with any amplified Sonos
player. The Sub is compatible with Sonos software versions 3.8 and later. Once
you have positioned the Sub in the room, you can press the Join button on the
side of the Sub in order for the system to recognize it. The system
automatically adjusts the audio settings to perfectly balance the Sub and the
paired Sonos component for best performance. All of the filter settings, active
equalization, and time alignment are done digitally through a state-of-the-art
Digital Signal Processor (DSP). During setup, you will be prompted, through the
Sonos Controller software, to set the subwoofer's level and phase. In some
cases, you will be prompted to select the size of the stereo speakers (compact,
bookshelf/ceiling, or floor) connected to the amplified player. If you move the
Sub to another room, you can easily reconfigure the audio and room association
Connections: The Sub has only two connections, both located on the
bottom of the enclosure: the power cord connection, and a single Ethernet port
(RJ-45) for connecting the Sub to a wired home network.
