Great question! We cannot say that One SL is able to be installed outdoors because it isn't designed for that. One SL does have a humidity resistant architecture, but it isn't designed to work in the extreme cold. If you were to do this, note that it isn't designed for it and you'd want to install it in a way that let you bring it in for the winter.

Hi, and thank you for your question. Unfortunately we cannot integrate Arc with your stereo system but worth noting that Arc has discrete surround sounds built into it. Arc would plug directly into the back of your tv with HDMI ARC, eARC, or Optical via the included optical adapter.

Hi, and thank you for your question. Yes you can! When you set up beam, we will automatically walk you through the remote set up with any IR remote. If your Beam is already set up, you can do this now by going to settings -> system -> select room name -> scroll down under TV setup you'll see "Remote Control Setup". We'll ask you to press volume +,-, and mute 3x's and that's it! :) - As always we're here to help you set that up if needed. Feel free to head over to sonos.com/support and reach out to us whichever way you prefer.

Hi, and thank you for your question. We would not recommend putting it in a closed cabinet for 2 reason. The first is heat dissipation. Although we use incredibly efficient amplifiers heat is still lost and needs a place to go. The other is wifi signal. Having a completely closed cabinet could interrupt wifi connection potentially depending on the material of the cabinet.
