Short answer: the KEF LS50 Wireless II for measured off-axis consistency, the KRK Rokit 5 G4 for a hifi-leaning listen. The Rokit 5 G4 has deeper bass than the HS5 and good horizontal directivity, its small woofer mating well with the waveguided tweeter, but it is not quite as detailed as the HS5. The LS50 Wireless II’s Uni-Q array measures the tightest directivity spread of this batch with a smooth listening window.
What the KEF LS50 Wireless II offers: Uni-Q coincident driver array (130mm aluminum woofer with a 25mm MAT dome tweeter mounted at its acoustic center) gives excellent, consistent off-axis dispersion, measuring the tightest directivity spread of this batch alongside a smooth listening-window response. The catch: Primary/Secondary architecture means one speaker handles every input while the other depends on a wireless or wired Ethernet link back to it - placement is less flexible than a fully symmetric pair.
Buy the KEF LS50 Wireless II. It is rated higher for sound quality, and the KRK Rokit 5 G4 is discontinued, so it is only available used.

Pros: Erin’s measurements give preference scores of 5.43 standalone and 7.51 with an ideal subwoofer, with a -3dB point around 51Hz. The coincident Uni-Q layout helps preserve tonal consistency across horizontal and vertical listening positions. Low listening-window narrow-band deviation of 0.308 supports relatively clean midrange reproduction. HDMI eARC and streaming functions make it a capable all-in-one stereo system. Measured bass extension of 51.3Hz (-3dB).
Cons: The 3.0dB response span is good but not reference-leading, and dispersion still varies with frequency. Compact bass drivers limit deep-bass output. App placement adjustments are not the same as microphone-based automatic room correction. The price and primary/secondary architecture are practical trade-offs; neither driver geometry nor a single directivity statistic guarantees the best sound in every room.

KRK Rokit 5 G4: $337 per pair Discontinued eBay
Newer model: the KRK Rokit 5 G5. It’s likely to perform similarly, though we don’t have measurements to confirm that yet.
Pros: ASR’s data gives -3dB bass around 56Hz and scores of 3.92 standalone and 6.29 with an ideal subwoofer. The waveguide provides useful horizontal directivity control, while onboard adjustments help tailor broad balance. The existing review reports low distortion at 86dB and low audible hiss. Measured bass extension of 55.7Hz (-3dB).
Cons: The 3.6dB midrange span and listening-window narrow-band deviation of 0.502 show that native response is not reference-flat. A port-region resonance and other tonal irregularities remain. Its deeper bass does not establish greater detail or mixing accuracy than another monitor. EQ can help, but the unequalized measurements determine the starting recommendation. Discontinued.
