A:AnswerThe speakers are passive. They do not need power, they only need the audio source from your amp.
Power --- AC power ---> Amp --- audio signal ---> Speaker
A:AnswerThank you for your question. A single Sonos Amp only controls one stream and volume level, no matter if you connect a single or multiple pairs to it. In order to have independent control you would have to use a separate Amp for each zone.
A:AnswerHi, and thank you for your question. Yes, as long as they are 4ohms speakers. Keep in mind that whatever speakers are plugged into the same amp will all play the same thing at the same time no matter what. Not a big deal if all 4 speakers are in the same room, but it can be if you're putting both sets in different rooms.
A:AnswerWe have no brand recommendations, however we do have gauge recommendations. Check out this article for that. https://support.sonos.com/s/article/4764?language=en_US
We also recommend running the wire in parallel.
A:AnswerHi, and thank you for your question. There are a few differences. These speakers are designed with a detection circuit that tells it that it's powered to our Amp. There are three major benefits because of that.
1) Customized DSP for each model of speaker (outdoor, in-wall, in-ceiling)
2) Ability to trueplay tune the in-wall, and in-ceiling models (https://support.sonos.com/s/article/3251?language=en_US)
3) You can run up to three pairs of speakers of this on one Sonos Amp compared to 2 pairs.
A:AnswerHi, and thank you for your question. No, they are not bluetooth. They are controlled wirelessly with the Sonos Amp!
They also do not have voice assistance built into them, but our Amp will connect to Alexa in our app, and via the Alexa app so that they can be controlled with voice. All you would need is an Amazon voice product, or you can use our voice assisted speakers.
A:AnswerYes. You need an amplifier to run these speakers. I recommend the Sonos Amp if you already use other Sonos equipment. The Amplifier will be indoors and speaker wires need to be run to speaker locations.
