Genelec 8351B vs Kali Audio IN-8 V2

Short answer: the Genelec 8351B for measured flatness, the Kali Audio IN-8 V2 for placement flexibility. The 8351B’s CEA2034 spinorama is exceptionally flat on and off axis, but deep bass distortion rises at 96dB SPL/1m and suffers below about 100Hz. The IN-8 V2’s front-ported coaxial cabinet allows near-wall placement without port noise, though it sounds notably forward in the 4-5kHz range on axis and wants about 10° of toe-out plus EQ.

Buy the Genelec 8351B when sound quality outweighs the price for you, and the Kali Audio IN-8 V2 when the price outweighs sound quality instead.

The Two Speakers In Full

Genelec 8351B: $9150 per pair B&H Photo Video eBay

Pros: The vertical ASR measurement scores 7.75 with an ideal subwoofer and reaches 35.2Hz at -3dB. Coaxial midrange and treble help maintain consistent sound as the listening angle changes. Low measured distortion at ordinary listening levels and GLM calibration make it a strong precision-monitoring choice. Measured bass extension of 33Hz (-3dB).

Cons: Bass distortion increases at higher playback levels, so a subwoofer remains useful for demanding material. Upper-treble distortion in the test also cautions against assuming unlimited output. Calibration hardware adds to an already expensive system, and the quoted result is for the measured vertical orientation.

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.
