Bring even, balanced sound to a larger or open-plan space with this WiiM AMP Ultra and OSD R83 ceiling speaker system, supplied with two pairs of speakers.
Four reference-grade 8" in-ceiling speakers spread the sound evenly across a bigger footprint, so the music stays consistent wherever you are in the room.
One compact WiiM amplifier powers the lot, streaming from the WiiM Home app and keeping your install tidy.
Ideal For: Larger open-plan kitchens, living spaces or two adjoining areas that need even sound from four ceiling speakers.
The four R83 speakers are wired as two pairs across the amplifier's left and right channels, presenting a 4 Ohm load the WiiM AMP Ultra is built to drive at 200W per channel.
The result is wider, more even coverage than a single pair can give, with every speaker playing the same source in perfect step.
- Four-Speaker Coverage: Two pairs of R83 ceiling speakers spread sound evenly across a larger or open-plan room.
- Driven By One Amplifier: The WiiM AMP Ultra powers all four speakers and is rated to handle the lower 4 Ohm load with ease.
- All-In-One Streaming: Built-in Wi-Fi with Spotify Connect, TIDAL, Qobuz and Amazon Music, with no separate streamer required.
- HDMI ARC For TV: Hook up a television for richer, clearer film and TV audio across the whole space.
- Reference-Grade Sound: Carbon fibre woofers and pivoting tweeters keep detail sharp at every listening position.
- Discreet, Flush Fit: All four speakers sit neatly into the ceiling for a clean, clutter-free finish.
