Short answer: the Kali Audio LP-6 V2. It ranks #37 of 119 powered bookshelf speakers by sound quality, rated 4.4/5, at $498; the Klipsch The Nines ranks #66, rated 4.2/5, and costs $899, so there is not much of a tradeoff to weigh.
Why pick the Kali Audio LP-6 V2: Affordable studio monitors with balanced sound and solid bass, plus switches to tune them for your room. Watch for: The 2.5dB response span from 300Hz to 5kHz leaves some tonal unevenness.
The case for the Klipsch The Nines: Powered horn speakers with even mids, solid bass, HDMI ARC and a phono input, convenient for both TV and music. It keeps a wired aux input, which the Kali Audio LP-6 V2 lacks. Watch for: The 6.90 ideal-subwoofer score reflects limitations beyond the narrow midband span.
Buy the Kali Audio LP-6 V2. It is rated higher for sound quality than the Klipsch The Nines and costs less, which makes it the one to get unless you need something the other one does better.
