Quick Answer: Sony BRAVIA Theater System 6 vs JBL Bar 700MK2 — Which 5.1 Home Theater Should You Buy in 2026?
Choose the Sony BRAVIA Theater System 6 if you want a conventional 5.1-channel layout with dedicated rear speakers, a center channel for dialogue, and Sony’s Multi Stereo mode. Choose the JBL Bar 700MK2 if you prioritize higher stated power, a larger 10-inch wireless subwoofer, and detachable wireless surround speakers. At the listed prices, the Sony costs $48.05 more, so the JBL is the stronger value unless Sony’s dialogue-focused layout matters most.

Performance
Core Performance
The two systems take different approaches to cinematic sound. The Sony BRAVIA Theater System 6 is presented as a 5.1-channel system built around three front-firing speakers, two rear speakers, and an included subwoofer. That physical arrangement gives the system a clear front stage and separate rear channels. Its dedicated center channel is particularly relevant for television viewing, since dialogue is assigned to a speaker designed for that role rather than being left to a generic left-right soundbar arrangement.
The JBL Bar 700MK2 emphasizes scale and impact. Its product description lists 780W maximum power, a wireless subwoofer with a 10-inch driver, and true 7.1-channel wireless surround sound. Those specifications make the JBL the more compelling choice on paper for action films, bass-heavy music, and listeners who want a system capable of producing a larger-feeling presentation. A power rating does not by itself establish sound quality, but it is a meaningful advantage in this comparison because Sony’s supplied product data does not include a directly comparable power figure.
Both systems support Dolby Atmos, so either can handle compatible immersive soundtracks. The Sony also supports DTS:X, while the JBL lists DTS Virtual:X. These are not identical labels: Sony’s specification names DTS:X support, whereas JBL’s description names a virtual surround format. Buyers with a large library of DTS:X content should therefore pay attention to that difference rather than treating the two format lists as interchangeable.
Handling & Ergonomics
The Sony follows the familiar physical-home-theater formula: place the main soundbar at the front, position the two rear speakers behind or beside the seating area, and use the included subwoofer for low-frequency effects. That makes the channel arrangement easy to understand, but the available information does not specify how the rear speakers connect or how much placement adjustment the system offers.
JBL’s defining usability feature is its detachable wireless surround design. The surround speakers lift off each end of the soundbar and can then be placed behind the listener. JBL explicitly describes the process as requiring no surround-speaker wires, which can be useful in rooms where running cable from the television area to the rear of the seating position would be inconvenient. The speakers can also be returned to the soundbar when a simpler front-of-room arrangement is preferred.
That flexibility does not make the JBL entirely cable-free: the soundbar, subwoofer, and rear speakers still need to be positioned and powered according to the system’s setup requirements. The supplied data confirms wireless surround-speaker operation and a wireless subwoofer, but it does not provide dimensions, weights, mounting details, or installation measurements. Treat those practical details as open questions before buying if your cabinet or wall space is limited.
Runtime / Fuel & Maintenance
Runtime and fuel economy do not apply to either product. These are powered home theater systems rather than battery-operated appliances. The relevant ownership considerations are installation, cable management, software or connection setup, and keeping the speakers and subwoofer clear of dust and obstructions.
The Sony package includes its subwoofer and rear speakers, while the JBL package includes a wireless subwoofer and detachable wireless surround speakers according to the supplied descriptions. Neither product’s provided data lists a battery-runtime figure for the surround speakers, a charging time, a replacement-battery schedule, or a power-consumption figure. Do not infer any of those specifications from the word “wireless.”
Best Use Cases
- Movies and TV dialogue: The Sony is the safer fit for shoppers who specifically want a dedicated center channel and a straightforward 5.1 layout.
- Action movies and bass: The JBL has the stronger stated hardware case, with 780W maximum power and a 10-inch wireless subwoofer.
- Flexible surround placement: The JBL is better suited to rooms where detachable wireless rear speakers are easier to position than permanently connected speakers.
- Immersive formats: Both support Dolby Atmos; Sony lists DTS:X, while JBL lists DTS Virtual:X.
- Whole-room playback: Sony’s Multi Stereo mode is designed to play the same sound from all speakers for a room-filling effect.
Maintenance & Running Costs
Neither system has listed consumables such as filters, brushes, bags, blades, or cleaning solutions. Routine care is therefore primarily cosmetic and environmental: keep dust from accumulating on the soundbar, rear speakers, and subwoofer, and avoid blocking speaker openings. The supplied research does not identify replacement drivers, service intervals, consumable parts, or a maintenance kit for either model.
The initial purchase price is the clearest running-cost difference in the available data. The JBL is listed at $549.95, while the Sony is listed at $598.00. That makes the Sony $48.05 more expensive before taxes, delivery, accessories, or any later discounts. Both systems include the major components described for their respective packages, so the comparison is not simply between a standalone soundbar and a complete system.
Wireless connectivity can reduce visible cable routing, but it does not eliminate the need to plan power access. The JBL’s detachable surround speakers and wireless subwoofer may be easier to arrange than a more conventional wired layout, while the Sony’s included rear speakers and center-channel design make its hardware configuration more traditional. Because the research does not specify cable lengths, replacement-part pricing, or warranty terms, those costs should be checked separately before purchase.
Features & Usability
Sony’s feature set is centered on channel separation and speech clarity. The BRAVIA Theater System 6 has three front-firing speakers, two rear speakers, and a dedicated center channel. Sony also includes Multi Stereo, which plays the same sound through all speakers to create a room-filling boost. This mode may be useful for everyday television, parties, or content that does not have a discrete surround mix.
Its format support includes Dolby Atmos and DTS:X. That gives the Sony a broad stated format range for compatible movies and shows. The product description also frames it as a system intended to deliver sound straight from cinema, but the available data does not provide independent measurements for frequency response, maximum loudness, dialogue accuracy, or Atmos height performance.
JBL’s strongest usability feature is the detachable surround arrangement. Instead of leaving the surround speakers fixed to the soundbar, the owner can lift them off each end and place them behind the seating area. JBL describes the system as delivering true 7.1-channel wireless surround sound, which is a more expansive channel claim than Sony’s 5.1 configuration.
The JBL also lists Dolby Atmos and DTS Virtual:X, 780W maximum power, and a 10-inch wireless subwoofer. Together, those features make it appealing to buyers who want a dramatic presentation without paying more than the Sony’s listed price. The limitation is that the supplied JBL data does not state a dedicated center-channel specification, a Multi Stereo-style mode, or independent dialogue measurements.
Price & Value Analysis
At the listed prices, the JBL Bar 700MK2 costs $549.95 and the Sony BRAVIA Theater System 6 costs $598.00. The difference is $48.05, with JBL costing less. The price gap is not large, but it matters because the JBL also lists 780W maximum power, a 10-inch wireless subwoofer, and detachable wireless surround speakers.
The JBL is worth the extra attention from value-focused buyers who want the most substantial specification package for the money. Its lower price, higher stated maximum power, 7.1-channel wireless-surround description, and larger stated subwoofer driver give it a convincing on-paper advantage. It is especially attractive if flexible rear-speaker placement is more important than having a dedicated center channel.
The Sony can justify its $48.05 premium for a different type of buyer. Its 4.6/5 listed rating is higher than the JBL’s 4.2/5, and its dedicated center channel, three front-firing speakers, included rear speakers, Dolby Atmos, DTS:X, and Multi Stereo mode create a focused feature set for TV and movie dialogue. Buyers who prefer Sony’s conventional 5.1 approach may reasonably pay more for that layout.
Do not read the price difference as proof that one system sounds better in every room. The available research does not include standardized listening scores, measured loudness, frequency-response graphs, distortion results, or room-size testing for these exact product listings. The best value depends on whether you prioritize JBL’s stated power and flexible wireless surround design or Sony’s dedicated center channel and higher listed customer rating.
