Short answer: the Genelec 8040B for better sound quality, the Kali Audio LP-6 for the lower price. The Genelec 8040B ranks #9 of 66 powered bookshelf speakers at $2350. The Kali Audio LP-6 ranks #31 at $298, $2052 cheaper.
What the Genelec 8040B offers: Based on their smaller speaker’s performance against others, I’m ranking this accordingly. Watch for: Very expensive
What the Kali Audio LP-6 offers: CEA2034 spinorama shows generally flat on-axis response with excellent horizontal and vertical directivity. Deep bass distortion stays below the fundamental tone throughout testing, and the noise floor is low enough that hiss isn’t audible at normal listening distance. Exceptional value at $298 per pair. Watch for: Port resonance creates bumps around 900Hz-1kHz in the frequency response. Distortion measurements are worse than the on-axis response alone would suggest. Diffraction causes a treble rise above 10kHz, and bass shelves down slightly in the low end.
Buy the Genelec 8040B if sound quality matters more than the price. Buy the Kali Audio LP-6 if the price matters more than sound quality.
