Question

How much does the Arc Ultra benefit from adding Era 100s or even a Sub-Mini?

Just installed a Sonos Arc Ultra below our TV (77” Sony A80J) in a room that is 20’ x 15’ (TV on the 20’ wall).  Trying to decide whether to add two Era 100s and perhaps a Sub-Mini, and thought I’d check here to see if there is a consensus how much the Arc Ultra benefits from adding Era 100s?  And, would adding a Sub-Mini add more to the Arc Ultra sound experience?  If adding Era 100s, can they be added to the front far left and right corners of the room, or should they go to the rear corners (which would cause them to be mostly in line with viewing/sitting positions rather than behind).

Thanks and Happy Holidays!

I find my Era 100s add a lot to my TV listening when the source material has sound in the rear channels. Some content, even if showing as 5.1 doesn't have much/any sound there.

If you don't object to sounds that should be coming from the back of the room coming from the front you can place the surrounds up front. That really sounded odd to me when I've tried it.

I have a larger room so I added a Sub 4 and it makes a big difference. I'd hate to have to choose between surrounds and a sub, both add to the experience.

If you’d want to use a Sub, I’d go for the Sub, not the Sub Mini. The Arc Ultra already has a bass speaker of it’s own, so in my opinion needs the bigger Sub.
