Short answer: the Genelec 8351B for better sound quality, the Kali Audio LP-6 for the lower price. The Genelec 8351B ranks #6 of 66 powered bookshelf speakers at $9150. The Kali Audio LP-6 ranks #31 at $298, $8852 cheaper.
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.
What the Genelec 8351B offers: CEA2034 spinorama shows exceptionally flat response both on- and off-axis. Predicted in-room response is “as good as it gets” - should sound very neutral in nearly any room. Horizontal beamwidth of about ±50 degrees is described by the reviewer as exceptionally smooth, a model example of well-executed directivity control. Vertical directivity is nearly as good as horizontal, a benefit of its coaxial driver design that’s rare among non-coaxial monitors. Distortion at 86dB SPL/1m is remarkably low - the reviewer says it’s “better than many headphones.” Watch for: Deep bass distortion rises substantially at higher output (96dB SPL/1m) - the reviewer notes “deep bass suffers” below about 100Hz. A distortion spike also appears near 8-10kHz at that same higher output level. Cumulative spectral decay (waterfall) measurements show resonances around 1-2kHz. Very expensive.
Buy the Kali Audio LP-6 if the price matters more than sound quality. Buy the Genelec 8351B if sound quality matters more than the price.
