The Sonos Sub is probably one of the best available in the market. When you paid with Sonos Bar or Sonos Beam you will get a sound quality that's unmatched by rival companies like Bose and will feel like cinema sound system. Set up is very easy over WiFi and can be operated by Sonos app. A little expensive for a sub, however worth evey penny!!

My Sonos SUB also just died, after 5 years.
The Sonos customer service team said to me 3% of their products are absolutely lemons and they expect their customers to return these and pay $700 (30% off RPP) for a refurbished one. They do not offer repair option which is an absolute joke, it could just be a burnt fuse. Such poor workmanship for a $1k speaker, its now an expensive paper weight.

Sonos has absolutely no confidence that their products would last, therefore only offer a 12 month warranty.

My $999 sub stopped working after 4 years, they wanted me to pay $690 to replace it with a refurbished unit. This is a joke as most good subs out there can last 10-20 yrs.

If you are after a banging cordless base, the sonos is second to none. Producing clear base, no matter how loud you have it cranked up.
The only downfall I don’t like about it is the shiny black. The dust gets stuck to it and any little scratch or knock shows up. A Matt finish would be perfect.
Otherwise I can’t fault this base, love it love it love it.

Clear bass. Good quality. Outstanding FREE AIR SUB. For the money it's perfect.good size. Great style and design. Can place it anywhere in a room and it look very classy with old and new furniture.

We purchased the first sub for our sunroom and simply had to have one for in the lounge. If you love great sound quality, then this sub is well worth considering at its price point. I have heard a number of people complaining about the Sonos wireless regarding drop-outs. If you buy the Sonos bridge and run the latest firmware updates on your equipment. This resolves any issues, I'm running three complete and separate Sonos systems in my home and have never had any problems with any of the equipment. This gear is top quality and produces excellent results, music becomes more pleasurable due to the performance of system across all frequencies. The clarity is what makes this system worth every cent spent.

The Sonos Sub is a stand alone unit with a sleek modern appearance and the added advantage of only one power cable Say goodbye to all those speaker cables, audio cables and the transformer power cable lead. Operating via WI Fi it can be placed in a powerpoint anywhere in the room The Sonos Sub enhances and improves the sound quality of both the Sonos 5 and Sonos Sound Bar. Easy to install, operate and connect to the sonos speaker system I would highly recommend the Sonos Sub for Sonos users seeking richer sound quality and good value for money.
