These were floor models. They have all been tested and are guaranteed for 30 days. Some do have noticeable cosmetic issues (see photos for details). These cosmetic issues do not impact the performance of these Subwoofers (the sound is fantastic). Pease do not purchase these units if you are expecting perfect cosmetic condition. These have been handled with less care than we would have preferred. Some have gotten nicks and scratches during shipping and handling. We do marginal clean on units, but we do not repair. We reserve the right to reasonably select the units we are shipping to any buyer. Requests for "Best one we have" will not be accepted. Included: Sub unit speaker, AC cable, CAT5 cable. See product details for more specific information regarding setup and performance. 

Please note - this is not intended to be a standalone speaker. for full functionality, this does require a wired connection initially, and then can be configured to that WiFi network using an the manufacturer App (requires a Sonos account) and an appropriate streaming device.
Direct connection to any other device requires digital optical output from that device.
If you are uncertain that you would be able to connect this to your existing setup, please consult an experienced user of Sonos products or an audio professional for advice prior to purchase.
We are not responsible for user failure to set up these devices, but will provide assistance as needed, in the form of online manuals and links to videos via email, after purchase, upon request.
