The Sonos Sub provides an instant upgrade to your Sonos Play speaker system, but it's quite pricey.

The, has a unique, eye-catching design and its wireless function works from anywhere in a room (though it does have to be plugged in); It really augments the sound of your Play speakers and the setup is a breeze

Its finish doesn't match any other Sonos components and the Sub doesn't work as well with the Connect: Amp; It's expensive and won't work outside of a Sonos system

Sonos is badass with its brainless setup, seamless backend that affords easy access to all of your music, and good sound from its standalone, networked, jukeboxe-y Zone Players. Notice the term "good sound". Not great sound.

It's a lot to pay for a subwoofer that can't be used with non-Sonos hardware. If you can swing the cost, though, you'll get a tremendous boost to sound quality that integrates smoothly with a full Sonos network.

Deep; tight bass; Easy setup; Unique design

Very expensive; Can't be used with non-Sonos gear; Dust magnet

Sonos, the company behind the multi-room wireless music system, has launched a wireless subwoofer to fit into any room, promising to boost the performance of the company's range of zone players instantly. But can it really be that easy?

Good bass; good design; easy setup

Big; expensive; maybe too loud

Exquisite design; Delivers serious bass; Wireless management

The big letdown is the price; $300 dearer than the USA

Our verdict on the Sonos Sub is tricky. On one hand you've got a mouth-wateringly expensive accessory for an already pricey range of products. On the other, you've got a truly brilliant piece of audio engineering that will transform turn your living room into a super club.

Simple set up; Great industrial design; Superb bass balance

Sonos, maker of a variety of excellent multi-room music systems , has added a high-end bottom end to its line up of powered speakers--the $699 Sonos Sub . More than just a subwoofer, the Sub incorporates into existing powered Sonos configurations to add a rich bottom end to your streaming music.

If there is one line of products with which I have been totally enamored it is the Sonos system I purchased a bit over a year ago. To recall my experience with Sonos: I had long been interested in the company and their wireless audio system, but I had never actually seen or heard one in action.

Simple setup; Visually impressive; Flexible and can be laid on its side, placed vertically or even placed under a couch; Adds a HUGE amount of bass and overall depth to an existing Sonos system

Pricey; Requires you to already have a Sonos system in place; Large size means it will not be ideal for small spaces; A few minutes with it and your "old" Sonos system will seem "less than
