Short answer: the Neumann KH 310 A for better sound quality, the Klipsch The Nines for the lower price. The Neumann KH 310 A ranks #13 of 62 powered bookshelf speakers at $4400. The Klipsch The Nines ranks #30 at $999.99, $3400.01 cheaper.
What the Klipsch The Nines offers: Erin calls these his favorite Klipsch speaker he has heard. With the tweeter trim set to -2dB, the listening-window response stays within roughly +/-1.5dB from 40Hz to just above 10kHz, and they produced genuinely powerful bass that reached about 30Hz in his room. The 8-inch woofer remains below 3% THD from 30Hz upward at 96dB/1m; compression is well controlled through about 90dB, and its limiter was not a concern at realistic listening levels. Exceptional all-in-one connectivity includes HDMI ARC, phono, USB, optical, Bluetooth, analog inputs and a subwoofer output; the Klipsch Connect app supplies useful bass/mid/treble adjustment. Watch for: The app’s flat setting leaves the treble elevated, and Erin preferred a -2dB tweeter trim. There is a likely tweeter/waveguide breakup feature around 16kHz, though he did not hear it. Horizontal coverage is narrow (about +/-30 degrees), prioritizing a focused image over room involvement; listeners who prefer a wider soundstage may not like that trade-off. Ear height matters: he recommends the reference plane between woofer and tweeter rather than directly on tweeter axis. The speaker begins limiting above roughly 90dB/1m, and the two cabinets still require a physical inter-speaker cable.
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.
Buy the Klipsch The Nines if the price matters more than sound quality. Buy the Neumann KH 310 A if sound quality matters more than the price.
