Short answer: the Neumann KH120 MKII for flat, extended response, the Kali Audio SM-5 for its true coaxial design. The KH120 MKII is about as flat as the reviewer has measured, staying flat almost to 50Hz, with just a minor directivity blip around 2kHz. The SM-5 mounts its tweeter inside the midrange, but bass output is limited by the 5” mid-bass driver.
Buy the Neumann KH120 MKII. It is rated higher for sound quality than the Kali Audio SM-5 and costs less, so only choose the other one for a particular feature it does better.

Neumann KH120 MKII: $2000 per pair B&H Photo Video eBay
Pros: ASR’s Klippel data shows exceptional neutrality: only a 1.5dB span from 300Hz to 5kHz and low listening-window narrow-band deviation of 0.208. Scores of 6.49 standalone and 8.44 with an ideal subwoofer place it among the strongest measured options here. Bass reaches -3dB around 45Hz. The review reports very low distortion at 86dB/1m and clean performance outside deep bass at 96dB. Measured bass extension of 46Hz (-3dB).
Cons: Vertical crossover interference makes listening height important even though horizontal dispersion is well controlled. A small directivity irregularity remains around 2kHz. Distortion increases below about 50Hz at high output; a subwoofer can extend the system and reduce low-frequency demands. High price, and a flat anechoic response still needs suitable placement in the room.

Kali Audio SM-5: $3000 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.
