Kali Audio IN-8 V2 vs Emotiva Airmotiv 6s

Short answer: the Kali Audio IN-8 V2. It ranks #38 of 113 powered bookshelf speakers by sound quality (rated 4.4/5) at $998 and is still sold new; the Emotiva Airmotiv 6s ranks #77 (rated 4.0/5) and is discontinued, so it is only an option used.

The Kali Audio IN-8 V2 is the better-sounding, deeper-bass pick. The IN-8 V2’s coaxial midrange/tweeter supports coherent imaging, and low distortion at ordinary levels complements its 7.30 ideal-subwoofer score. Its bass reaches about 44Hz before falling 3dB, against 49.1Hz for the Emotiva Airmotiv 6s. The tradeoff: The measured 3.0dB response span from 300Hz to 5kHz includes unevenness that can make some vocals sound forward.

Why pick the Emotiva Airmotiv 6s: ASR measured 49.1Hz -3dB bass extension and a 5.75 ideal-subwoofer score. The catch: The 3.0dB response span from 300Hz to 5kHz includes lower-midrange unevenness that can change vocal weight.

Buy the Kali Audio IN-8 V2. It is rated higher for sound quality; the Emotiva Airmotiv 6s is no longer sold new.

Kali Audio IN-8 V2: $998 per pair Amazon eBay

Same family: the Kali Audio IN-5 (smaller bookshelf, rated 4.2/5) and the Kali Audio IN-UNF (larger bookshelf, rated 3.3/5).

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.

Emotiva Airmotiv 6s: $800 per pair Discontinued eBay

Pros: ASR measured 49.1Hz -3dB bass extension and a 5.75 ideal-subwoofer score. The review found useful output capability, making it a credible option for ordinary nearfield playback with additional bass support when needed. Measured bass extension of 49.1Hz (-3dB).

Cons: The 3.0dB response span from 300Hz to 5kHz includes lower-midrange unevenness that can change vocal weight. Treble peaks also prevent a fully neutral balance. Equalization may help, but the substantially higher EQ-optimized score is not its native performance. A suckout between 300 and 600Hz in the listening window is followed by a peak from 600Hz up. Discontinued.
