Add a more immersive rear-channel experience to a compatible Sony soundbar setup with the Sony SA-RS5 180 W Wireless Rear Speakers. This pair of wireless rear speakers is designed to work with compatible Sony soundbars and features built-in batteries, allowing flexible placement without requiring a continuous power connection.
Each speaker combines an up-firing speaker, wide-directivity woofer, soft-dome tweeter and dual passive radiators. The up-firing speakers reflect sound from the ceiling to contribute to a more immersive overhead audio experience, while the woofer, tweeter and passive radiators help create a wider soundstage with enhanced low-frequency reproduction.
With 180 W total output (90 W per speaker), 10-hour battery life and wireless connection to a compatible soundbar, the SA-RS5 gives you greater flexibility when positioning rear speakers around your room. The speakers can also be wall-mounted or placed on a suitable surface, while Sound Field Optimisation helps configure the speakers to the room.
Key Features
180 W Total Power Output
A rear-speaker setup needs enough output to make surround effects clearly noticeable. The SA-RS5 delivers 180 W total output, with 90 W allocated to each speaker, providing dedicated amplification for the left and right rear channels.
Up-Firing Speakers for Immersive Sound
Conventional rear speakers direct sound primarily toward the listener. The SA-RS5 incorporates up-firing speaker units that direct sound toward the ceiling, helping create a more immersive overhead audio effect when used with compatible Sony soundbars and supported surround formats.
10-Hour Built-in Battery
Keeping rear speakers connected to power can restrict placement around the room. The SA-RS5 has a built-in battery offering up to 10 hours of battery life, allowing the speakers to operate without a continuous AC connection under specified usage conditions.
10-Minute Quick Charge
When you need the speakers again quickly, a 10-minute quick charge can provide up to 90 minutes of playback. This makes short charging periods more useful when the speakers have been left without sufficient charge.
Wide-Directivity Woofer & Soft-Dome Tweeter
The SA-RS5 uses a wide-directivity woofer and soft-dome tweeter in each rear speaker. This combination is designed to provide a wider soundstage while maintaining clarity across different parts of the audio spectrum.
Dual Passive Radiators
Low-frequency reproduction can be difficult to maintain from compact rear speakers. The SA-RS5 uses dual passive radiators to enhance low-end tones, adding more bass presence to rear-channel audio.
Wireless Rear-Speaker Connection
Running cables from a soundbar to rear speakers can make installation more complicated. The SA-RS5 connects wirelessly with a compatible Sony soundbar, reducing the need for speaker signal cables between the soundbar and rear speakers.
Flexible Placement
The speakers can be placed on a suitable surface or wall-mounted, giving you more flexibility when arranging the rear channels around your listening area. Their built-in batteries also allow cable-free operation when sufficiently charged.
Sound Field Optimisation
Getting rear speakers positioned correctly can affect the overall surround experience. The SA-RS5 includes a dedicated OPTIMISE function that works with a compatible soundbar to measure speaker and ceiling distances and help optimise the sound field for the room.
