I authored the above discussion about 2 years ago. However, I think it's still relevant (as far as basics) and appropriate for this group.
Sonos has since pushed out a few updates to the Arc and introduced a speaker (Era 300) that can be used as rears x 2 to complete the Dolby Atmos experience. I've added dual subs to my setup.
As the Arc is pushing the 5 year mark what improvements do you believe are needed (if any) to keep the Arc as a viable Dolby Atmos speaker/soundbar? It’s too early to discuss changes/improvements to the Era 300; and the Era 500 is still just a rumor. Even if it were introduced it might be overkill as a surround much like the Fives are in some situations.
My improvement to the Arc would be a better center channel for dialogue. I’m not sure how pass-through would be a need other than a “me too” versus the competition. More licensed Codes might be a request? The more drastic move would be to ditch the Arc and introduce left/center/right separates? I don’t see that happening… then who’s to say? There was a time when only I believed there’d be a speaker like the Era 300. I say that based upon discussions of the pass in this community.
Take a look at my original post and please leave your comments on it and that which I have just put forth in this group discussion. Looking forward to your thoughts!
