Sonos debuts wireless sub-woofer

Jun 20, 2012

[Updated Jun 20, 2012] – Sonos, maker of a line of wireless, Internet-streaming music systems, has added a sub-woofer to its offering. The “Sub” adds “soul-shaking, heart-pounding” bass to any of the company’s amplified components, says Sonos.

Sonos is well known for its broad family of high quality devices capable of playing music streamed from a variety of Internet and local sources wirelessly — and synchronously — to locations throughout the home.

The photo below shows the new Sub along with the company’s earlier Play:3, Play:5, and Connect:Amp components.

All that’s necessary to add the Sub to an existing Sonos installation is to plug it in, press a button on the device, and follow a few simple prompts on the iOS or Android remote control app.

The Sub contains two force-canceling speakers, positioned face-to-face. The speakers are driven by a pair of Class D digital amplifiers, whose filter settings, equalization, and time alignment are digitally optimized to maximize acoustic volume and enhance bass resonance.

DeviceGuru was treated to a demo of the Sub’s capabilities at the infamous Hyde Street Studios Studio D in San Francisco last week, and consequently we can attest to the Sub’s impressive performance. The setup, shown below, consisted of a Sub plus a pair of Play:3 powered systems. It was hard to believe all that crisp, clean, full-bodied sound emanated from such small boxes!

Sonos says the Sub’s amps “have been perfectly tuned to match the speakers and acoustic architecture,” and its cabinet is designed with a proprietary resin that “produces acoustically dead walls with maximum internal air volume.” The unit measures 15.8 x 6.2 x 15 inches and weighs 36.3 lbs.

Here’s a YouTube video, made by Sonos, showing some of what went into the design and testing of the Sub wireless amplified speaker:



The making of the Sonos Sub

 

Sonos system architecture

At its grandest, the Sonos whole-home audio system comprises a collection of music-streaming players and wireless bridges scattered around the home, which collectively implement a private WiFi-based mesh network with synchronized music playback as shown below (note: Sonos revised its product names after publishing the following figure).

Despite its mesh orientation, a minimal Sonos setup can consist of a single Play:3 or Play:5 component networked to the home LAN via a wired Ethernet connection. To that, you might add the new Sub component for dramatically enhanced bass.

Availability

The company is currently shipping the Sub, priced at $699. For more information on Sonos’s Internet-enabled wireless music systems, read DeviceGuru’s earlier Sonos review, and visit the company’s website.
