Same family: the Cambridge Audio L/R S (smaller bookshelf, rated 4.4/5) and the Cambridge Audio L/R M (smaller bookshelf, estimated 4.2/5).
Pros: Active speakers with HDMI eARC, a phono input, Wi-Fi streaming, wide even dispersion, and solid bass. An active 2.5-way speaker pair with HDMI eARC, a phono input, Wi-Fi streaming and measured bass down to 43Hz (-3dB). Each speaker has a 28mm aluminum tweeter, a front-facing 5-inch mid-woofer, a second 5-inch woofer at the base whose passband overlaps the first (the source of the “.5”), and dual 6-inch side-firing passive radiators. Erin’s Audio Corner measured wide, even horizontal dispersion (a broad flare out to about the -6dB point around 1.5 to 3kHz) and deeper extension than the smaller L/R S, with an F3 of about 43Hz and F10 of about 37Hz. In-app DSP for room size, speaker distance from the front wall, and reflective surface type gave an audible change in bass tightness in testing. Connectivity also covers RCA aux, optical digital, USB-C, USB-A and a subwoofer output, making it a full living-room hub rather than just a stereo pair. Measured bass extension of 43Hz (-3dB).
Cons: On-axis response is less linear than the L/R S, with dips in the bass, a peak around 1-2kHz, and a dip spanning the upper mid-range into the lower treble; Cambridge confirmed the dip is a deliberate DSP notch for a tweeter breakup resonance rather than a driver flaw, but it was audible as a mild suck-out in an AB pink-noise comparison. Vertical dispersion is narrower and asymmetric than the L/R S, at about plus 20 to minus 10 degrees, because the greater distance between the tweeter and mid-woofer creates more lobing, so listening height and stand placement matter more. Multitone distortion rides close to the 3% threshold at 96dB measured at 1 meter in the far field, limiting headroom for loud, wide-band material. Output falls off quickly below about 50Hz, so home-theater use with deep bass content benefits from an added subwoofer.
Is the Cambridge Audio L/R X right for you?
Buy it if
- you want to connect a TV over HDMI.
- you want deep bass without a subwoofer (-3 dB at 43 Hz).
Skip it if
- you want the best value: the higher-rated JBL 308P MKII costs about $2,101 less.
