Q: I keep reading the specs for this new unit, but I can't find any information about humidity resistance. I've got two Sonos 1's on my covered patio and they've worked great for years, but I'd like to add this new sub just to give better bass in this area.

A: Although you are explaining that you are using in an indoor like environment, but actually a patio is an outdoor location, and the humidity will always be at a range that is not possible to achieve indoors. Therefore, I would not consider this machine to be suitable for your purpose, however, based on what I see, and the content of the subwoofer during a break down Analysis that I saw in YouTube, I think it should be able to handle most humidity, since it is mostly plastic parts, and very few metal parts that can corrode in high humidity. However, I did not see the electronic component of en cased in the specialized humidity - proof box, so I would expect the life expectancy of this to be much lower than average if you were to leave it in a patio, even though it is covered from rain.

Q: Will this work with two outside Definitive Solutions speakers?? Looking to get something to amplify the sound for the two speakers. Thank you 😊

A: This can work with those speakers if they are powered by the Sonos Amp. Worth noting, it's not designed for outdoor use.

    Sonos Sub Gen. 4

    The Sonos Sub Gen 4 is a fantastic addition to any home theater setup. From the moment I added it, the bass became deeper and more powerful, making movies and music feel much more immersive. Explosions and action scenes hit harder, and the sound feels like it surrounds you, bringing the whole experience to life. When paired with the Sonos Era 300s and the Sonos Arc Ultra, the sound quality is incredible. The Era 300s handle the mid and high tones with great detail, the Arc Ultra adds rich surround sound, and the Sub Gen 4 fills in the low end with booming bass you can feel. Together, they create a full, lively soundstage that makes watching movies way more exciting. The main downside is the price but it’s definitely a premium setup. But for the quality and seamless integration Sonos offers, it’s worth it if you want top-tier sound. The wireless design and build quality make it easy to use and stylish too. If you want your sound to feel alive and immersive, this combo is a killer choice.

    Sounds great, weighs less

    Look great and sounds great. Can't tell the difference from a gen 3. The mate finish goes with the rest of the sonos line. I have two arcs in the living room one already has a gen 3 sub. This will go on the other arc or it could be a second sub on the first arc. Also have two fives in the living room. All of them playing music at once sound pretty amazing. You can notice a difference with a second sub. You could just turn up the bass on one sub. It does sound even better with two also evens out where the bass is coming from. Seems to be coming from everywhere. Also says made in China. My gen 3 was made in Malaysia.

    Sonos Gen 4 subwoofer

    This Sonos subwoofer is emasculate. The sound is just like the theater. It’s pairs very well with the Sonos arc ultra. It works great with music as well as thriller, horror, and action movies. I definitely give this 10 stars if I had to. This was one of my greatest purchases and I will be buying more Sonos products.Lets just say everyone wants to come over and enjoy the sound. Pop some popcorn, sit back and enjoy the theatrics!Very easy setup on your phone and it took about 5 minutes.
