KEF R11 Meta vs Sonos Arc

“The R11 is just the R3 with added woofers. From 400hz up to 20khz it's all the Uni-Q driver playing. The difference being that you'll be having a non-Meta Uni-Q in the R11 instead of the better Meta one in your R3. Don't get the R11. It's a waste of money. A subwoofer does a much better job in producing bass than an array of small woofers. The R11 may have an advantage in settings where there's no subwoofer. But if a subwoofer is an option, R3 Meta + subwoofer beats R11 hands down.”

“The Sonos System will not outperform dedicated speakers for each of the channels. These type of systems try to replicate dedicated speakers by bouncing the sound off of the ceiling. Even under the most optimal conditions (a flat, non vaulted ceiling that bounces sound perfectly), a very basic dedicated speakers system will still outperform the Sonos. I would only recommend a sound bar like the Sonos if you are extremely tight on space or can't compromise on aesthetics. Since you already invested in a very good projector and large screen - the Sonos should not even be considered at this point.”
