What Watt rms do Sonos have?

Oh, you are comparing two very different units using a single data point from a very complex interaction of data points? Well, that's a different story.

Playbar: 72 watts
Beam: 64 watts.

Hope that is of help.

thank you so much. Appreciate it

Rather than trying to get a power number for the various amplifiers in the devices you are looking at, just count speakers and compare case volumes. That will give you a decent comparison of the abilities of each unit.

Nope, i Am note buying eight play 5s, but i want the new outdoor system to have the same punch as eight play 5s.

I’m going to hook up a good quality amp with 8channels to 6-8 outdoors speakers. And then connect the amp to a Sonos connect.

I have seven of the Play 5 units (GEN 2), and they are amazing sounding when all playing together. I took one apart and connector high level convertors on the speaker leads to give me low level signal. Then buttoned it all up so now I have six channels of low level signal from each unit. This went into my amplifier that I then connected to my outdoor speakers. I purchased some old Sonance Marine speakers with dual 5.25" speakers and one tweeter in the center. They are powered nicely and with the active equalization from the Play 5, the speakers sound just like a Play 5 but louder and play lower since the 5.25" are bigger and in a ported box. I used two Sonance Marine speakers and it covers the outside beautifully. It is almost as if I have a subwoofer and for open-air, it is impressive.

You are compounding your ignorance by shining a light on it with your use of abuse.
