Arc Ultra Placement

Hi everyone,

I’m looking for advice on the optimal placement of a Sonos Arc Ultra. The current offer is ending soon, so I’d really appreciate any quick guidance.

I’ve attached photos of my full TV cabinet. The Arc Ultra would be placed on the second shelf, which currently measures 147 × 13.5 × 6.3 cm. We’re planning to remove the wooden panels from the top and bottom, which would increase the height clearance to around 9.5 cm.

For additional context, the distance from the bottom of the TV to the start of the soundbar shelf is 14 cm, so I believe the recommended TV clearance requirement is covered.

I’ve seen mixed opinions online, so I thought I’d ask here. We can also remove all four wooden sections if needed, as they appear to be glued in. I’d prefer to avoid wall mounting, as this alcove cabinet was built specifically with a soundbar in mind.

Given these dimensions, would it be safe to go ahead with the Arc Ultra and still get the best performance from it? My main concern is whether the alcove and shelf dimensions would negatively impact the upward- and side-firing drivers.

Due to the room size, I’m not planning to add a Sub or rear speakers, just the soundbar itself.

Any advice from Arc Ultra owners or Sonos experts would be greatly appreciated. Thanks in advance

JMHO… The ArcUltra isn’t a viable solution for your confined space. Out of curiosity… what panels are you considering removing that would benefit the ArcUltra placement. I can’t determine where the panels are located as the doors below IMO have no effect.

​@Stanley_4  - 

Thanks a million for your response. I'm just trying to better understand the option you're suggesting.

When you say "above the TV", do you mean mounting it in the white panel area below the TV or suspending it from the top shelf/cubby above the TV?

The reason I ask is that there isn't any meaningful space above the TV within the TV alcove itself—the TV almost completely fills the opening. I'm therefore struggling to visualise exactly where you would position the Arc.

I've actually created an AI-generated image of what I think Option 1 might look like. Is this what you had in mind, or have I misunderstood your suggestion? Could you clarify which location you have in mind?

Also, are Option 1 and Option 2 actually very similar in purpose, but they differ in where the bracket is attached.? Thanks again.

Option 1 -

Just as a note (mostly because I’ve failed at this), the hole ​@Stanley_4 mentions needs to be big enough to fit the end (connector) of the cable, not just the cable width itself…;)
