Wireless Home Cinema without a soundbar

I recently bought an Xgimi projector (optical and hmi e arc) and 120” screen to start improving my at-home movie experience , and now that the image quality is on point , I’m starting to work on a proper audio setup. The problem is that I know nothing about speakers and audio setups :) .

Here’s the thing though : my apartment is an attic apartment , the slanted ceiling can be a challenge to work with and , as a result, I only had a single proper rectangular wall on which to install the screen . It also happens to be the wall with the sliding door to the bedroom right in the middle of it . Now that’s not a problem at all for the screen which unrolls right in front of it . But when it comes to sound installation , that makes it impossible to place a soundbar underneath the screen since it would be overlapping the door . I would have to place the soundbar to the side and 50cm off the ground , which doesn’t seem like a good idea (and would greatly limit furniture placement and be quite unsightly anyway) . So I’ve been looking at satellite options like the Hisense HT Saturn as well as the Sony Theater quad which would be able to provide a 4.1.2 or 4.1.4 setup WITHOUT needing any center speaker or soundbar , but both of those products have their pros and cons so I was wondering if there was a way to achieve a similar setup with Sonos products for comparison .

Basically anything that can provide a good surround experience , ideally wireless connecting an amp or something else to the projector isn’t a problem since it’s in a corner of the room and I have plenty of power outlets . Having wires stretching all around the room from the projector/amp would be more annoying . But my understanding is that all Sonos wireless setups use the soundbar as the “brain” of the system to drive the other speakers . Is it possible to get the “brain” part as a standalone without the speakers to create anything 4.1 or 5.1 without much latency ? It doesn’t seem like the Port can achieve that . The amp would need to be directly wired to passive speakers , unless it can be used to pilot active speakers (without actually amping anything) ???

I was thinking that 2 Eras 300s , 2 Eras 100 and a sub would make for a good setup (maybe 4 100s and a sub would do the job) but what I’m missing is the wireless amp that can control it all and that ISN’T a soundbar . Can the Sonos Amp actually pilot those 5 speakers with 4.1 channels ? Would it only be able to do stereo ?

No. The soundbar is required to be wired to an ARC output, and it functions as the ‘brain’.

Alternately, you can wire an Amp via that ARC connection, and you can use it to drive your own speakers (right and left), and it will use those two signals to create a ‘faux’ center channel. 

Sonos does not have a system where a separate device acts as an interpreter, and you can use multiple Sonos speakers to connect to it.

To add…

The Amp as ​@Airgetlam suggested to drive left right speakers can also be used to communicate with Era 300’s or Era 100’s as surrounds (recommend the Era 100’s). In any event you’ll have an HDMI cable running from the Amp to the HDMI port on the projector. As many in this community have a similar question when using a projector the bottom-line is that Sonos is not designed to be used with a projector.

Despite a few pleas here in these forums, Sonos has not yet released a device designed for projector ease of use. It’s easy from my perspective to say that the market is so small as to not be profitable for them, but that’s an assumption. I don’t know why they haven’t yet. It could just as easily be a technical issue, potentially with bandwidth, but that is merely guessing.

What would be handy is a hybrid, copper/optical Arc/eArc cable with no length issues like you see on copper only ones. The small size and concealability of the fiber strand would be nice too.

We are seeing that from a few folks for Ethernet so there may be hope.
