Short answer: the Neumann KH 310 A for better sound quality, the Kali Audio LP-6 for the lower price. The Neumann KH 310 A ranks #13 of 66 powered bookshelf speakers at $4400. The Kali Audio LP-6 ranks #31 at $298, $4102 cheaper.
What the Neumann KH 310 A offers: CEA2034 spinorama shows a near-perfect on-axis response with superb directivity control and minimal off-axis variation. Distortion measured very low at 96dB SPL/1m. Bass stays clean and dry without bloat, and vocals show no harshness. Tri-amplified design delivers 290W combined output and up to 116.3dB SPL. Watch for: An unidentified dip around 80Hz shows up in the measurements, which Neumann was asked to investigate. Bass response shifts somewhat with amplifier temperature. Distortion rises above 100% THD at the very bottom of the bass range, as expected at that extreme. Expensive at $4,400 per pair.
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 Neumann KH 310 A if sound quality matters more than the price. Buy the Kali Audio LP-6 if the price matters more than sound quality.
