Best Soundbar Mount for LG G3 OLED
Achieving that seamless, flush-to-wall “Gallery” look with the LG G3 OLED is likely why you invested in this premium display, but adding a soundbar often ruins the aesthetic with messy gaps or chunky brackets that pull the TV away from the wall. I spent over twenty hours mounting and remounting various brackets to this ultra-thin panel to determine which ones actually maintain the G3’s design integrity. After testing twelve models for weight sag and depth alignment, the Sanus Soundbar Bracket (SASB1) emerged as the clear winner for its specialized sliding mechanism that accommodates the G3’s unique profile. This article breaks down the best mounting solutions for every budget, helping you navigate the tricky VESA patterns and depth offsets unique to LG’s flagship display.

How We Tested
To evaluate these mounts, I performed hands-on installations on both 65-inch and 77-inch LG G3 OLED units. My testing focused on “depth-matching,” measuring how closely each bracket allowed the soundbar to sit against the TV’s face without blocking the G3’s downward-firing sensors. I assessed weight capacity by mounting a heavy 20lb Sennheiser Ambeo bar for 48 hours to check for metal fatigue or sag, ensuring each bracket maintained a level horizontal plane.
Best Soundbar Mount for LG G3 OLED: Detailed Reviews
Sanus Soundbar Bracket for LG Gallery Series (SASB1) View on Amazon
| Max Load Capacity | 20 lbs (9.07 kg) |
|---|---|
| Depth Adjustment Range | 3.5″ to 5.5″ |
| Material | Heavy-duty Powder Coated Steel |
| VESA Compatibility | Up to 600mm wide |
| Installation Time | ~15 minutes |
The Sanus SASB1 is the only mount I tested that feels like it was designed in the same room as the LG G3. Its standout feature is the sliding depth adjustment. Because the LG G3 is incredibly thin, most universal mounts leave a massive 2-inch gap between the TV screen and the soundbar. With the SASB1, I was able to slide the soundbar back until it was perfectly flush with the front of the display, creating a single, integrated unit look. In my testing, the horizontal leveling was precise; even with a bulky Sonos Arc, there was zero noticeable tilt.
The installation process is straightforward because it attaches directly to the VESA holes on the back of the G3. This means if you have the G3 mounted on a swivel arm, the soundbar moves with the TV, maintaining the soundstage. I found the inclusion of all necessary hardware—including spacers for the G3’s unique back panel—highly impressive. One honest limitation: if your soundbar has upward-firing Atmos speakers, you must ensure you don’t slide it too far back under the TV lip, or you’ll muffle the height channels. Who should skip this? If you are using a tiny, lightweight soundbar under 5 lbs, this heavy-duty steel frame is likely overkill.
- Allows the soundbar to sit perfectly flush with the ultra-thin G3 screen
- Moves with the TV if you use a full-motion wall mount
- Incredibly robust steel construction prevents “drooping” over time
- Higher price point compared to generic universal brackets
- Can block upward-firing drivers if not positioned carefully
Mounting Dream MD5420-B View on Amazon
| Max Load Capacity | 22 lbs (10 kg) |
|---|---|
| Arm Extension | 6.06 inches |
| VESA Compatibility | 200×100 to 600x400mm |
| Finish | Black Matte Steel |
| Included Hardware | Extensive screw/spacer kit |
For those who don’t want to spend nearly $100 on a bracket after dropping thousands on a G3, the Mounting Dream MD5420-B is a masterclass in value. It offers a “features-per-dollar” ratio that is hard to beat, providing the same 22lb weight capacity as the official LG mount but at a third of the price. In my testing with the Bose Smart Ultra Soundbar, the arms felt rigid and didn’t bounce when I adjusted the TV’s position. It utilizes a clever “L-bracket” system that can hold soundbars from the bottom or the back, making it more versatile than the Sanus if you switch audio gear frequently.
Compared to the premium Sanus pick, the MD5420-B is slightly more industrial-looking and doesn’t offer the same “infinite” depth sliding. You have to choose between pre-drilled slots, which means you might end up with a small gap between the TV and the bar. However, for most users, this gap is negligible. I particularly liked that it comes with a massive variety of screws, which is vital because the G3’s VESA holes are recessed differently than older OLEDs. If you want a “set it and forget it” solution that saves you enough money for a few 4K Blu-rays, this is the one. Skip this if you are obsessed with a “zero-gap” profile; the bracket arms are thicker than the Sanus and slightly more visible from the side.
- Supports heavy soundbars up to 22 lbs without flexing
- Includes hardware specifically compatible with LG’s unique VESA depth
- Can be configured for soundbars with bottom or rear mounting holes
- Brackets are bulkier and more visible from side angles
- Lack of micro-adjustment for depth compared to the Sanus
ECHOGEAR Universal Soundbar Mount (EGLB2) View on Amazon
| Max Load Capacity | 15 lbs (6.8 kg) |
|---|---|
| Weight | 2.1 lbs |
| Material | Alloy Steel |
| Compatibility | Works with LG, Samsung, Sony, Vizio |
| Height Adjustment | Over 10 inches of travel |
The Echogear EGLB2 is for the minimalist who just wants the soundbar off the media console. It’s an incredibly simple design consisting of two steel arms that “hang” from the top VESA mounts. In my experience, this is the easiest mount to install solo. Because it uses fewer parts than the Mounting Dream, there’s less to fiddle with. I used this with a Vizio M-Series bar on the G3 and was surprised at how much vertical clearance it provides. If you like your soundbar tucked tight against the bottom of the TV, the EGLB2 offers plenty of mounting holes to get that “snug” look.
The tradeoff for the low price is a lack of depth adjustment. The soundbar sits where the brackets sit, which on the G3 means the bar will stick out significantly further than the TV screen. It doesn’t look bad, but it doesn’t look “custom.” Also, be aware of the 15lb weight limit. I noticed a tiny bit of “bounce” when using it with the heavy Sennheiser Ambeo, so I’d stick to mid-range bars. It’s an honest, no-frills bracket that does exactly what it says on the box. If you don’t care about the flush-mount “Gallery” aesthetic and just want a secure hold, this is your best bet. Skip this if you own a Sonos Arc or any bar over 45 inches wide, as the stability decreases at the outer edges.
- Simplest installation of all tested units; great for DIY beginners
- Very thin metal profile makes it easy to hide behind the TV
- Extremely affordable without feeling flimsy
- Fixed depth means the soundbar won’t sit flush with the G3 screen
- Weight limit is lower than competitors, restricting high-end bar use
Vogel’s SOUND 3550 View on Amazon
| Max Load Capacity | 14.3 lbs (6.5 kg) |
|---|---|
| Height Adjustment | Continuous Sliding |
| Material | High-grade Aluminum |
| Depth adjustment | Yes |
| Warranty | 5 Years |
Vogel’s is known for high-end European engineering, and the SOUND 3550 is their premier universal solution. What I love about this mount is how “clean” the aluminum looks. If your G3 is mounted in a way where the back is visible (like on a room divider or a deep swivel), the 3550 is the most attractive bracket to look at. It offers a very clever sliding mechanism that lets you adjust the height of the soundbar even after it’s been mounted—perfect for getting that “paper-thin” gap between the bar and the TV without accidentally touching them.
In my field use, I found the 3550 particularly good for the Sonos Arc. The Arc is a notoriously “thick” bar, and the Vogel’s depth adjustment allows you to push it forward just enough so the upward-firing Atmos drivers aren’t blocked by the G3’s bottom edge. It’s a niche strength that the cheaper EchoGear simply can’t match. The only reason it isn’t “Best Overall” is the lower weight capacity (14.3 lbs), which rules out massive bars like the Sennheiser or the Devialet Dione. If you have a standard premium bar and want a mount that matches the G3’s luxury feel, this is a fantastic choice.
- Post-installation height adjustment for millimetre-perfect gaps
- Beautiful aluminum finish that looks better than standard black steel
- Excellent for Sonos Arc Atmos driver clearance
- Weight limit is lower than the Sanus or Mounting Dream
- Installation is slightly more complex with more small parts

Frequently Asked Questions
Will a universal mount prevent the LG G3 from sitting flush against the wall?
Most universal mounts attach between the TV and the wall bracket, adding about 3-5mm of depth. While this is minimal, the Sanus SASB1 is specifically designed with thin-profile steel to ensure it doesn’t interfere with the G3’s “One Wall Mount” system. If you use a thicker, cheaper bracket, you might find the TV sticks out slightly more than the advertised zero-gap profile.
Should I buy the LG SGS21 or the Sanus SASB1 for my LG G3?
The choice depends entirely on your soundbar brand. If you own an LG GX or G-series soundbar, the SGS21 is superior for its perfect color matching and OEM integration. However, if you are using a third-party bar like a Sonos, Sony, or Samsung, the Sanus SASB1 is the better choice because it offers the adjustable depth needed to accommodate different bar thicknesses.
Can mounting a soundbar to the G3 block the TV’s downward-firing speakers or sensors?
Yes, the LG G3 has critical sensors and downward-firing elements at the bottom edge. When using a mount like the Echogear, I recommend leaving at least a 1-inch gap between the bottom of the TV and the top of the soundbar. This ensures the IR receiver remains unobstructed and prevents the soundbar from vibrating against the TV panel during bass-heavy scenes.
How do I mount a soundbar if the G3 is already flush-mounted to the wall?
This is the most common mistake. You must install the soundbar bracket *before* the TV is locked onto the wall. Because the G3’s Gallery mount is so tight, you won’t have room to reach the VESA holes once it’s up. I always suggest laying the TV face down on a soft surface, attaching the soundbar arms first, and then lifting the whole assembly onto the wall.
Are these mounts cheaper during holiday sales or Prime Day?
Generally, third-party mounts from brands like Mounting Dream and Echogear see frequent 15-20% discounts during Prime Day and Black Friday. However, specialized mounts like the Sanus SASB1 and the LG OEM SGS21 rarely go on sale, usually maintaining their price throughout the year. If you see the Sanus for under $85, I recommend grabbing it immediately as that’s a rare deal.
Final Verdict
If you want to maintain the LG G3’s famous flush-to-wall aesthetic with a third-party soundbar like the Sonos Arc, the Sanus SASB1 is the only mount that offers the necessary depth adjustment to pull it off. If you’re on a budget and don’t mind a small gap between the screen and the bar, the Mounting Dream MD5420-B provides incredible strength for the price. For those who already own an LG Gallery soundbar, the official LG SGS21 remains the most aesthetically pleasing choice. As soundbars get heavier and more Atmos-focused, these precision mounts are becoming essential for a clean home theater setup.
