Quick Question-

I recently purchased a new house which has 8 in-ceiling speakers connected to a 2 channel stereo receiver. I am planning on buying a port to connect to the receiver, so that I can add these in-ceiling speakers to my sonos ecosphere.

I already own a sonos beam, sub, (2) play 1s, and a move that I have been using in my previous home. I read that it isn’t possible to “attach” the sub to the port (or the in ceiling speakers). My question is this: If I attach the sub to the beam as I have in the past, and then pair the beam/sub to the port so they all play the same thing in unison?

Thanks,

Ben
