Short answer: the Cambridge Audio L/R X. Both are rated 4.1/5 for sound quality (#48 and #44 of 68 powered bookshelf speakers), and the Cambridge Audio L/R X costs $2399 against $3199 for the Barefoot Footprint 01, and with sound quality even, the cheaper one is the better buy.
What the Cambridge Audio L/R X does well: 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. The tradeoff: 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.
The case for the Barefoot Footprint 01: Measured bass reaches 35.2Hz at -3dB, giving substantial low-end weight. The catch: The 6.70 ideal-subwoofer score and 2.9dB response span from 300Hz to 5kHz indicate tonal unevenness relative to the strongest monitors.
Buy the Cambridge Audio L/R X. Both are rated the same for sound quality, and it costs $800 less than the Barefoot Footprint 01.

The Two Speakers In Full
Cambridge Audio L/R X: $2,399.00 per pair Amazon eBay
Pros: 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. 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.

Barefoot Footprint 01: $3,199 per pair B&H Photo Video eBay
Pros: Measured bass reaches 35.2Hz at -3dB, giving substantial low-end weight. Its active multiway format and opposed bass drivers offer a compact professional system, with a 5.48 standalone preference score reflecting useful full-range capability.
Cons: The 6.70 ideal-subwoofer score and 2.9dB response span from 300Hz to 5kHz indicate tonal unevenness relative to the strongest monitors. Driver count and opposed-woofer construction do not guarantee neutral room sound. Careful placement and correction remain worthwhile.
