Short answer: the Adam Audio S2V for driver integration, the Kali LP-6 for measured directivity. The S2V blends its 7 inch woofer and AMT tweeter through an imperceptible crossover with distortion 70dB down at 1kHz, but an intentional shelving curve dips the low bass roughly 200-500Hz. The LP-6’s port resonance bumps its response around 900Hz-1kHz, yet it keeps excellent horizontal and vertical directivity.
What the Kali Audio LP-6 offers: CEA2034 spinorama shows generally flat on-axis response with excellent horizontal and vertical directivity. Watch for: Port resonance creates bumps around 900Hz-1kHz in the frequency response.
Buy the Adam Audio S2V. It is rated higher for sound quality; the Kali Audio LP-6 is no longer sold new.

The Two Speakers In Full
Kali Audio LP-6: $298 per pair Discontinued eBay
Newer model: the Kali Audio LP-6 V2, ranked higher, rated 4.4/5.
Pros: The original LP-6 measures 43.9Hz at -3dB and scores 6.33 with an ideal subwoofer. Its waveguide and placement controls make it a credible budget studio monitor, with useful bass for ordinary music listening. Measured bass extension of 43.9Hz (-3dB).
Cons: The measured 2.9dB response span from 300Hz to 5kHz is less even than the newer LP-6 V2. First-generation amplifier hiss can be distracting at short distances. Do not assume the V2’s noise improvements or measurements apply to this model. A port resonance adds bumps around 900Hz to 1kHz. Discontinued.

Adam Audio S2V: $3,399.98 per pair Amazon eBay
Pros: A 7.98 ideal-subwoofer score and relatively even listening-window response support a strong role as a subwoofer-assisted studio monitor. The review’s low-distortion findings add useful evidence beyond amplifier ratings, and onboard DSP permits tailored adjustment. The review measured distortion about 70dB below the signal at 1kHz. Measured bass extension of 52.7Hz (-3dB).
Cons: Measured -3dB extension is 52.7Hz, so the large cabinet does not automatically deliver the deepest bass here. The native balance rises toward the treble, with some lower-midrange unevenness. DSP can improve that balance, but an EQ-optimized result is not its unadjusted performance.
