Cambridge Audio L/R X: Designed In-House

Cambridge Audio was founded in 1968, and the L/R X is designed by its in-house team, which Cambridge calls its most ambitious work in active loudspeakers. The proprietary 28mm tweeter uses a dual-radius aluminum dome, a custom waveguide, a phase ring and an advanced rear-chamber design for detail and depth.

Side-Mounted Passive Radiators

The L/R X uses dual 6-inch passive radiators, mounted on the sides, instead of a port. Cambridge says they produce the low-end weight of much larger speakers, with extension you can feel down to 35Hz. The L/R X is tuned for free-standing speakers, and the Room Acoustics sliders in the StreamMagic app let you match the bass to your room and placement.

Front and Downward-Firing Woofers

Each L/R X uses two 5-inch woofers, one front-facing and one hidden and firing downward, which together retrieve detail into the lowest frequencies. With the 6-inch passive radiators, frequency response is 35Hz to 24kHz (+/-3dB), and Cambridge says the L/R X delivers deep bass without the need for a separate subwoofer.

WiSA: No Cable Between Speakers

This is the feature that separates the L/R X from the L/R M, which links its speakers by USB-C cable. WiSA (Wireless Speaker and Audio) technology creates a high-quality wireless link between the primary and secondary speakers. Each speaker simply needs power. No cable running across the floor, behind the couch, or under a rug.

This matters most in real living rooms. If you want speakers flanking a fireplace, a mantle, or a wide entertainment center, running a cable from one speaker to the other is a genuine obstacle. With the L/R X, you plug each speaker into the nearest outlet and they find each other automatically. You can still use a USB-C cable to tether them if you prefer a wired connection, but the wireless option is there and it works without compromising audio quality.

64-Bit DSP and Advanced Speaker Protection

With 800 watts on tap, the L/R X has serious power reserves, and the 64-bit DSP pipeline makes sure all of that power is managed intelligently. The DSP runs the digital crossovers and DynamEQ, and Cambridge says Advanced Speaker Protection preserves performance when the volume rises, so you can push the L/R X hard on those big nights in. For a pair of speakers that might live in a family room, a media room, or anywhere that other people have access to the volume control, that's a meaningful assurance.

StreamMagic Gen 4: Every Source, One System

The L/R X runs Cambridge Audio's 4th generation StreamMagic platform, handling Spotify Connect, TIDAL Connect, Qobuz, Amazon Music, Deezer, plus internet radio natively. Over a wired network it plays high-resolution files up to 384kHz and DSD256. AirPlay 2, Google Cast, and Roon Ready support mean it integrates into any multi-room setup you already have, or serves as the foundation for a new one.

Connectivity for Every Source in Your System

HDMI eARC connects to your TV and lets you control volume with your existing remote. The built-in moving magnet phono stage takes a turntable directly, no external preamp needed. USB-C handles computer audio, USB-A plays from media drives, and Optical TOSLINK covers legacy sources. Bluetooth is there for casual streaming. There's also a subwoofer output if you want to add one, though at 35Hz extension, most listeners won't need it.

Six Finishes, Including Premium Walnut

The L/R X is available in six finishes: Black, White, Orange, Green, Blue, or Walnut. Cambridge calls the walnut a premium finish, and it carries a modest premium at $2,499/pair (vs. $2,399 for the other finishes). A floating base and subtle LED underlighting complete the design.
