I want to know which sonos speaker, i can use for CHURCH Audio Visual (AV) Setup

Since all Sonos speakers that have an analog input have a 75ms delay, for A/V connection, you’ll need optical, ARC or eARC, but without knowing any details regarding this setup, it’s hard to say. 

First… Sonos in this community typically deals with home solutions which I wouldn’t recommend for a church. Several factors say no…

• Building Size
• Large number of People that cause interference with WiFi

However, if you are set on Sonos I recommend clicking the link:

Another alternative is to use the Sonos Amp and wired 3rd party speakers. Click the link:

The above options may or may not be available in your country.

I would not recommend Sonos for use in a church, as Sonos cannot be used well with microphones or live music.  If you have a specific need to show recorded presentations in a classroom setting, or perhaps only background music in a meeting hall, Sonos could work.
