Short answer: the JBL 308P MKII for a flatter on-axis response. Its spinorama is essentially flat from 45Hz to above 15kHz with almost no directivity error, though a resonance around 18kHz and a slight dip near 1.4kHz remain. The Kali IN-8 V2 is the three-way coaxial with front porting for near-wall placement, but it is notably forward in the 4-5kHz range on axis and needs about 10° of toe-out.
Buy the JBL 308P MKII. Both are rated the same for sound quality, and it costs $700 less than the Kali Audio IN-8 V2.

Kali Audio IN-8 V2: $998 per pair Amazon eBay
Pros: The IN-8 V2’s coaxial midrange/tweeter supports coherent imaging, and low distortion at ordinary levels complements its 7.30 ideal-subwoofer score. Measured -3dB extension of 45.4Hz provides useful bass; boundary settings assist placement. The front port allows placement near a wall without port noise problems. Measured bass extension of 44Hz (-3dB), with a measured sensitivity of 89dB.
Cons: The measured 3.0dB response span from 300Hz to 5kHz includes unevenness that can make some vocals sound forward. Bass and limiter behavior constrain high-level playback. These measurements apply to the V2, not the first-generation IN-8. On-axis, the 4 to 5kHz range sounds forward; Kali recommends about 10° of toe-out, and some EQ helps.

JBL 308P MKII: $298 per pair Amazon B&H Photo Video eBay
Pros: A 1.8dB response span from 300Hz to 5kHz and 7.69 ideal-subwoofer score support unusually good tonal balance for an accessible studio monitor. Measured -3dB extension of 42.5Hz supplies useful musical bass, and the waveguide helps maintain consistent horizontal coverage. Measured bass extension of 42.5Hz (-3dB).
Cons: Amplifier hiss may be noticeable in quiet, close-range use. Bass distortion and output limits matter when playing loudly, despite the 8-inch woofer. Keep the tweeter near ear height; vertical crossover behavior is less forgiving than the best coaxial designs. A resonance around 18kHz and a slight dip around 1.4kHz.
