Short answer: the Cambridge Audio L/R M. Both are rated 4.2/5 for sound quality (#30 and #26 of 105 powered bookshelf speakers), and the Cambridge Audio L/R M costs $1,599 against $2,998 for the Kali Audio SM-5, so with nothing between them on sound quality, price settles it.
What the Cambridge Audio L/R M does well: The middle model of Cambridge’s L/R active range, between the L/R S and L/R X. Watch for: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured L/R S and L/R X.
Why pick the Kali Audio SM-5: Erin’s measurements show bass reaching -3dB around 43Hz and a 2.8dB midrange response span. Watch for: Scores of 5.18 standalone and 7.13 with an ideal subwoofer are good but below the leading reference monitors, so its advanced driver layout does not justify a near-top ranking by itself.
Buy the Cambridge Audio L/R M. Both are rated the same for sound quality, and it costs $1,399 less than the Kali Audio SM-5.
Worth knowing: the Cambridge Audio L/R M has not been measured yet. Its rating is estimated from related models, with a likely range of 3.8 to 4.5, so treat this verdict as provisional.

The Two Speakers In Full
Cambridge Audio L/R M: $1,599.00 per pair Estimated Cambridge Audio eBay
Same family: the Cambridge Audio L/R S (smaller bookshelf, rated 4.4/5) and the Cambridge Audio L/R X (larger bookshelf, rated 4.1/5).
Pros: The middle model of Cambridge’s L/R active range, between the L/R S and L/R X. Each speaker pairs a 28mm tweeter with a 4” woofer and a 4.75” passive radiator, driven by 150W, and Cambridge specifies 40Hz to 24kHz (±3dB), so it reaches deeper than the 3”-woofer L/R S. Inputs cover nearly any source: HDMI eARC for a TV, a moving-magnet phono stage, optical, USB-C audio, RCA and Bluetooth, plus app-based room and placement correction and a subwoofer output.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured L/R S and L/R X. Passive radiators extend bass in place of a larger woofer, so very loud low bass will compress sooner than from a bigger cabinet, and Bluetooth is limited to SBC and AAC.

Kali Audio SM-5: $2,998 per pair B&H Photo Video eBay
Pros: Erin’s measurements show bass reaching -3dB around 43Hz and a 2.8dB midrange response span. The coaxial mid/tweeter and large waveguide give useful consistency horizontally and vertically, reducing sensitivity to listening height. Built-in per-speaker DSP and mounting options make placement flexible. Existing testing reports low midrange distortion at 96dB. Measured bass extension of 45Hz (-3dB).
Cons: Scores of 5.18 standalone and 7.13 with an ideal subwoofer are good but below the leading reference monitors, so its advanced driver layout does not justify a near-top ranking by itself. A small upper-midrange irregularity remains. The five-inch woofer and limiter constrain loud bass; the review places compression onset roughly in the 96-102dB/1m region.
