Best Soundbars for LG B6 OLED TVs With Clearer TV Sound (2026)

The 2016 LG B6 OLED still shows a superb picture, but its thin cabinet leaves dialogue quiet and bass light, so the right bar matters. This guide compares eight best soundbars for lg b6 buyers can connect over HDMI ARC or optical, explains what the TV can and cannot pass, and helps you pick a simple bar, a bar with a subwoofer, or a full set.

Quick verdict: eight bars that fit the 2016 LG B6

Start with the LG S60T if you want the simplest LG match, or the Samsung HW-B750F if you want a full 5.1 set at a value tier. The Sonos Beam (Gen 2) suits a smaller room, the Bose TV Speaker fixes quiet dialogue, and the JBL Bar 500 adds the deepest bass here. Read the table first, then the section that matches your room.

Our pick for most B6 owners is the LG S60T, a direct LG match with a centre channel and a wireless subwoofer that needs nothing the TV cannot provide. For real surround sound, the Samsung HW-B750F is the stronger value-tier choice, while the Sonos Beam (Gen 2) suits a small room where music matters too.

Quick comparison table

The table below puts the eight picks side by side, so you can compare channels, what ships in the box, sound formats and the connection each bar uses with the B6. Every pick here works over HDMI ARC or optical, which are the two audio outputs this 2016 TV provides. Use it to narrow the list to two or three bars before reading the detail.

How we selected the bars for this guide

Every bar in this guide is a real product with published specifications from its maker or a retailer listing, and every one connects to the B6 over HDMI ARC or optical. We compared channel layout, included hardware, dialogue help, Atmos behaviour over ARC, and expansion options, and we left out bars that need eARC or duplicate a stronger pick.

This guide is based on published manufacturer specifications and independent review coverage. It does not claim testing of its own, and it does not rank products by review scores, because scores use different methods and change with each update. We also left out step-up LG bars whose headline features need a newer TV, since WOW Orchestra works only with compatible LG TVs from 2022 onward and the 2016 B6 is not listed.

The best soundbars for lg b6 in detail

Eight bars cover very different rooms and budgets, so the order below follows the decision most B6 owners face first: a simple LG match, a compact bar, a dialogue fix, a full 5.1 set, or a low-tier Atmos bar. Each section states what ships in the box, what the B6 connection allows, and when a simpler or larger option is smarter.

LG S60T: the LG match with a wireless subwoofer

The LG S60T is the most direct LG match in this guide, and that is why it leads the list for B6 owners who want a simple setup. It is a 3.1-channel bar with a dedicated centre channel and a wireless subwoofer, so dialogue stays clear while movies and music gain the low end the thin TV speakers cannot produce.

Retail listings put the S60T at 340 watts in total, so treat that figure as a retailer listing, not an LG specification figure. The bar carries Dolby Audio rather than Dolby Atmos, which fits the B6 well, because the TV sends Dolby Digital 5.1 over HDMI ARC and optical, and the centre channel keeps speech clear while the wireless subwoofer adds the low end.

Buy it if you want the simplest LG pairing for a B6 and you can live without Dolby Atmos height effects. Skip it if you want up-firing height speakers or rear surround in the box, since this is a TV-first bar with a subwoofer rather than a multi-room speaker.

LG S40T: the simplest LG upgrade for a small room

The LG S40T is the simplest budget-tier LG upgrade for a B6 in a bedroom or a small living room. It is a 2.1-channel bar with a wireless subwoofer, Clear Voice Plus for dialogue and an HDMI ARC connection that matches the TV, so setup is one cable plus power for the subwoofer.

Retail listings put the S40T at 300 watts in total, with 100 watts in the bar and 200 watts in the wireless subwoofer, which uses a 6-inch driver. It plays Dolby Digital and DTS Digital Surround, with AI Sound Pro and Clear Voice Plus for dialogue, and it connects over HDMI ARC or optical, with Bluetooth 5.3 for music. One retail summary also claimed Dolby Atmos for this model, but no Atmos is claimed here, since the LG feature list names Dolby Digital and DTS Digital Surround.

Buy it if your B6 sits in a bedroom or a small living room and you want the lowest-tier LG upgrade with a real subwoofer. Skip it if you want Dolby Atmos or rear speakers in the box, since this is a compact two-piece set rather than a surround system.

Sonos Beam (Gen 2): the compact bar for dialogue and music

The Sonos Beam (Gen 2) is the compact pick for a B6 in a smaller room, and it earns that place with a tidy 25.6-inch bar that also plays music well. It decodes Dolby Atmos over HDMI ARC in compressed form using virtual height, since the TV has no eARC port and the bar has no up-firing drivers.

Sonos lists a 5.0-channel layout with five Class-D amplifiers, one centre tweeter, four midwoofers and three passive radiators, in a bar only 25.6 inches wide. It connects by Wi-Fi and Ethernet, with AirPlay 2 for music and an optical adapter in the box, plus Speech Enhancement and Night Sound modes for dialogue late at night. There is no Bluetooth, no subwoofer in the box, and no HDMI input, so every source must connect to the TV first. A Sonos subwoofer and Era 100 rears can be added later.

Buy it if your B6 is 55 inches or smaller, your room is small, and you want a tidy bar that also plays music well. Skip it if you need strong bass for action movies without adding a subwoofer, or if you expect full lossless Atmos, since the B6 can only send the compressed form over ARC.

Bose TV Speaker: the simplest fix for quiet dialogue

The Bose TV Speaker is the pick for B6 owners whose main complaint is quiet dialogue, not missing bass or surround sound. It is a single compact bar with a centre tweeter and a Dialogue Mode button on the remote, and it connects over HDMI ARC or optical, both of which the 2016 TV provides.

The Bose TV Speaker is a single bar with three drivers: two angled full-range drivers and a centre tweeter tuned for speech, with a Dialogue Mode button on the remote and adjustable bass. It measures about 23.4 inches wide and 2.2 inches high, connects over HDMI ARC or optical, with a 3.5 mm subwoofer output and Bluetooth 4.2, and it has no Wi-Fi and no Dolby Atmos. It plays Dolby Digital up to 5.1, which is exactly what the B6 can send over ARC or optical. This guide describes the original model, not a later second-generation model sold in other regions.

Buy it if dialogue clarity is your main complaint and you want the smallest, simplest bar in this guide. Skip it if you want deep bass or surround sound without buying more hardware, since no subwoofer or rear speaker ships in the box.

Samsung HW-B750F: a full 5.1 set at a value tier

The Samsung HW-B750F is the value-tier pick for B6 owners who want a complete surround set without paying for Atmos features the TV cannot fully use. It is a 5.1-channel system with six speakers and a wireless subwoofer, and it connects over HDMI ARC, which fits its Dolby Digital 5.1 sound exactly.

Samsung lists a 5.1-channel system with six speakers and 400 watts in total, plus a wireless subwoofer, in a bar 40.6 inches wide. It plays Dolby Digital 5.1 and DTS Virtual:X, with Bass Boost, Adaptive Sound and Voice Enhance, and it connects over HDMI ARC or optical. Optional SWA-9250S rear speakers can be added later for true surround. Q-Symphony is listed for this bar, but it needs a compatible Samsung TV, so a B6 owner gets no benefit.

Buy it if you want a complete bar-and-subwoofer surround package at the lowest tier in this guide and you can live without Dolby Atmos. Skip it if you need Dolby Atmos or an eARC connection, or if your TV is small enough that a 40-inch bar will overhang the stand.

JBL Bar 500: the simplest 5.1 setup with deep bass

The JBL Bar 500 is the pick for B6 owners who want the deepest bass and the simplest 5.1 setup in this guide. It pairs a 5.1-channel bar with a 10-inch wireless subwoofer and MultiBeam processing, and its PureVoice mode keeps dialogue clear when action scenes get loud.

JBL lists a 5.1-channel system at 590 watts in total, with 290 watts in the bar and 300 watts in the wireless subwoofer, which uses a 10-inch driver. MultiBeam processing widens the sound, PureVoice keeps dialogue clear, and the bar supports Dolby Atmos with a 4K Dolby Vision passthrough. The bar has an HDMI eARC port, but the B6 only offers standard ARC, so Atmos arrives in compressed form. There is no DTS support and no rear-speaker support, so this is a bar-and-subwoofer system, not an expandable surround set.

Buy it if you want the deepest bass in this guide in a simple two-box setup and you watch a lot of action movies. Skip it if you need DTS:X, if you plan to add rear speakers later, or if a 10-inch subwoofer will overwhelm a small room.

Vizio M512a-H6: surround and height in one older set

The Vizio M512a-H6 is the only pick here that puts real height speakers, a wireless subwoofer and wired rear speakers in one older box. It is a 5.1.2-channel system with Dolby Atmos and DTS:X, plus HDMI eARC, an HDMI input and optical, so it connects to the B6 even though the TV cannot feed it lossless Atmos.

The Vizio M512a-H6 is a 5.1.2-channel system with 11 speakers, including two up-firing height drivers, a wireless subwoofer and two wired rear speakers. It supports Dolby Atmos and DTS:X, with an HDMI eARC port, an HDMI input, optical and a remote in the box, and its listed output is 103 dB. Over the B6, Atmos arrives only in compressed form over ARC. This is an older model, and the Vizio store now lists its newer SV and SL bars instead, so check the seller, the condition and the return terms before buying.

Buy it if you want real height and rear speakers in one purchase and you accept buying an older model through another retailer. Skip it if you want a current model, if wired rears will not work in your room, or if you need a bar that is easy to move, since this is a four-box system.

TCL S55H: Dolby Atmos with a subwoofer at a low tier

The TCL S55H is the low-tier Atmos pick for a B6 owner who wants a bar and a subwoofer without a large outlay. It is a 2.1-channel bar with a 5.5-inch wireless subwoofer, Dolby Atmos and DTS Virtual:X, and it connects over HDMI ARC, with Bluetooth for music from a phone.

TCL lists a 2.1-channel system at 220 watts in total, with a 5.5-inch wireless subwoofer, Dolby Atmos and DTS Virtual:X, in a bar 31.9 inches wide. It offers six EQ presets, AI Sonic room calibration and Bluetooth 5.3, and it connects over HDMI ARC. The Atmos effect here is processed rather than physical, since a 2.1-channel bar has no up-firing drivers, and over the B6 it arrives in compressed form, so expect a wider sound rather than height from above.

Buy it if you want an Atmos-labelled bar with a subwoofer at the lowest tier in this guide and your B6 is 55 inches or smaller. Skip it if you want discrete height speakers or rear surround in the box, since this is a compact two-piece set.

What to check before you buy a soundbar for the B6

A soundbar is a room purchase as much as an electronics purchase, so the checks below matter more than the channel count on the box. Measure the TV stand, find the HDMI ARC port on the TV, and think about where a subwoofer and any rear speakers will sit before you choose a tier.

How to match the best soundbars for lg b6 to your room and TV size

Room size decides the system before price does, so start with the space rather than the specification sheet. A compact bar suits a bedroom or a small apartment living room, while a larger open room needs a wider bar, a real subwoofer and rear speakers behind the sofa to fill the space.

For a 55-inch B6, which is about 48 inches wide, a bar between 31 and 40 inches wide looks balanced, and three picks here sit in that range. For a 65-inch B6, which is about 57 inches wide, the 40.6-inch Samsung HW-B750F is the widest pick here, so measure the stand, not the TV. A bar that overhangs the stand is a daily annoyance.

HDMI ARC, optical and the Atmos limit on the B6

The connection on the back of the B6 decides which sound formats the bar can receive, so check it before you buy. HDMI ARC carries compressed Dolby Atmos and Dolby Digital 5.1, while optical carries Dolby Digital 5.1 and stereo, and neither port on this 2016 TV carries lossless Atmos or eARC audio.

The B6 is a 2016 TV, so its HDMI ports run at 4K and 60Hz with HDCP 2.2, and the audio return port is HDMI 2, marked as HDMI ARC. That port sends Dolby Digital and compressed Dolby Atmos from the TV apps and connected sources, while optical sends Dolby Digital 5.1 and stereo. Most bars here have no HDMI input, so every source connects to the TV first. Check the exact model number, OLED55B6P or OLED65B6P, before buying, because LG later reused the B6 name for a 2026 TV with eARC, which is a different product.

Budget, setup and the costs buyers often miss

The price tier of the bar is only part of the cost, so plan for the extras before you decide. A single bar needs one HDMI cable and a power outlet, while a full system needs power outlets for the subwoofer and each rear speaker, plus a mount if the bar does not sit on the TV unit.

Optional subwoofers and rears for the Sonos Beam (Gen 2) are sold separately, so a compact bar can cost far more once the system is complete. The Vizio set needs cable runs to its wired rears, the Samsung and JBL sets need a power outlet for the subwoofer, and the LG bars need only one outlet for the subwoofer. If the household rents or moves often, a single bar or a two-piece set is easier to pack than a system with rear speakers.

Frequently asked questions about soundbars for the B6

The questions below cover the doubts that come up most often before a purchase, from whether optical still works to which features the 2016 TV simply cannot provide. Each answer follows the same rule as the rest of this guide: it states what the specifications support, and it names the case where the answer changes.

Will the best soundbars for lg b6 work over optical?

Yes, every bar in this guide that lists an optical input will work with the B6 over optical, and the Bose TV Speaker, the Samsung HW-B750F and the LG bars are the most direct optical options here. Optical carries Dolby Digital 5.1 and stereo, so it suits dialogue and surround sound, but it cannot carry Dolby Atmos at all.

Does the B6 support eARC or 4K at 120Hz?

No, the 2016 LG B6 does not support eARC or 4K at 120Hz, and no soundbar can add those features to the TV. Its HDMI ports run at 4K and 60Hz, its audio return port is standard HDMI ARC, and its optical output is the second audio option, so buy for ARC and optical, not for eARC.

Do I need rear speakers for a B6 in a small room?

Not usually, because rear speakers need space behind the sofa and power outlets, and a small room can sound crowded with a full 5.1 set. A compact bar with a subwoofer, such as the LG S40T or the Sonos Beam (Gen 2) with a subwoofer added later, usually fills a bedroom or small living room better.

Conclusion

Start with the LG S60T for the simplest LG match, or the Samsung HW-B750F for a full 5.1 set at a value tier. If dialogue or size matters more, the Bose TV Speaker and the Sonos Beam (Gen 2) cover those needs well. Check the HDMI ARC port on your B6, measure your room, and choose the bar you will enjoy every day.
