I have been audiophile all my life and I just want to say this is by far the best speaker I have ever owned. Having default settings on 0 treble and 0 bass with loudness turned on with truplay activated. This is all you need once again thanks sonos and the team for creating something out of this world

Hi ​@BigHazard 

Welcome to the Sonos Community!

I am glad to hear that you are more than happy with your Sonos Arc Ultra! Thanks for sharing!

@BigHazard, I completely agree with you. It is getting to the point where I honestly cannot watch television without the Sonos system turned on now.

However, unlike you, I find myself constantly tweaking the sound settings, especially when I am switching between different types of content like films and music. I have also had a very similar experience with the overall quality, though I am still trying to get the best out of Dolby Atmos. At the moment, I am not quite getting those immersive 3D sound effects, and I suspect the reason might be that my system is still missing a second Subwoofer to really balance out the room.

About the only tweaks I do (normally) is to fiddle speech enhancement and night sound.

-- Not normally, if my hearing aids batteries are dead I boost the treble.

With my room a single Sub is more than adequate but for difficult rooms, or wanting a lot of impact from video, a second one can be nice.

You have hit the nail on the head there, ​@Stanley_4. I am currently running my system with just a single Sub, but I used to have a dual setup previously. In my experience, if you are after that true, room-shaking cinematic rumble, having two units is unmatched.

It is fascinating just how responsive the hardware is to any minor tweaks we make in the app. A slight adjustment to the sub levels or the crossover totally transforms the entire soundstage. That flexibility and responsiveness is exactly what makes the system feel like a proper premium setup, as you can really tailor it to the room.

I can attest that room size is a key component as to how a Sonos HT setup sounds. I think my 25 x 18 x 8 room is perfect for my ArcUltra, Era 300 surrounds with Sub 4 x2. Dolby Atmos is cinematic especially on disc.

On the other hand I have the same setup in an open concept space with a single Sub 4. In that room the Sub 4 is located behind the sofa backed up to a wall. The low-end is great as I can feel it which IMO approximates the same experience in the smaller space above.

Bottom-line is that without tweaking the low-end proper placement of the sub can make a world of difference when trying to get the right balance in any space.

Finally if the space is cathedral like it will be challenging to get an immersive feel. Therefore, can’t blame Sonos as some spaces just don’t lend themselves to an immersive experience.

I'm fond of placing Subs in corners at a 45° angle for maximum coupling to the room. 

I have a smaller room with two Rooms, an HT and a 300 Atmos setup. The HT corner Sub is a lot more impressive than the mid-wall 300 sub even though it sits a few inches from my toes at my desk. Both together are fun but the imaging is pretty much destroyed, just really loud mono.
