Short answer: the Cambridge Audio L/R X for better sound quality, the Focal Alpha 65 EVO for the lower price. The Cambridge Audio L/R X ranks #47 of 67 powered bookshelf speakers at $2399. The Focal Alpha 65 EVO ranks #50 at $499, $1900 cheaper.
What the Cambridge Audio L/R X offers: A 2.5-way active design with 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 per speaker. 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 covers HDMI eARC, RCA aux, a moving-magnet phono input, optical digital, USB-C, USB-A, Wi-Fi streaming, and a subwoofer output, making it a full living-room hub rather than just a stereo pair. Watch for: 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.
What the Focal Alpha 65 EVO offers: ASR measured 42.5Hz -3dB extension, providing useful low-end reach for music. Analog input options and tonal controls make it straightforward to integrate into a studio, with a 5.71 ideal-subwoofer score indicating respectable but not leading tonality. Watch for: The measured 2.7dB response span from 300Hz to 5kHz and listening-window variation do not support a claim of reference-level neutrality. Placement and external correction may help. An anomalous distortion result from an individual sample should not be treated as a proven defect in every unit.
