Short answer: the Neumann KH 310 A if sound quality matters most, the Klipsch The Nines if price matters most. The Neumann KH 310 A ranks #20 of 113 powered bookshelf speakers, rated 4.6/5, at $4,998. The Klipsch The Nines ranks #63, rated 4.2/5, at $999.99, $3,998.01 cheaper.
Why pick the Klipsch The Nines: The 1.7dB response span from 300Hz to 5kHz supports even mids, and measured -3dB extension is 42.5Hz. It keeps a wired aux input, which the Neumann KH 310 A lacks. Watch for: The 6.90 ideal-subwoofer score reflects limitations beyond the narrow midband span.
The Neumann KH 310 A is the more accurate, deeper-bass option. The sealed three-way design combines 35.2Hz measured -3dB extension with low distortion in the review’s demanding playback tests. Its measured preference score, a predictor of how neutral it sounds, is 6.21 against 5.32 for the Klipsch The Nines. Its bass reaches about 35.2Hz before falling 3dB, against 42.5Hz for the Klipsch The Nines. The catch: Its measured tonal balance is not as even as the KH 150 or the best coaxial alternatives.
Buy the Klipsch The Nines when the price outweighs sound quality for you, and the Neumann KH 310 A when sound quality outweighs the price instead.

The Two Speakers In Full
Klipsch The Nines: $999.99 per pair Crutchfield eBay
Newer model: the Klipsch The Nines II, ranked higher, estimated 4.3/5.
Same family: the Klipsch The Fives (smaller bookshelf, rated 4.3/5) and the Klipsch The Sevens (smaller bookshelf, ranked lower, rated 3.7/5).
Pros: The 1.7dB response span from 300Hz to 5kHz supports even mids, and measured -3dB extension is 42.5Hz. Extensive consumer connections and app adjustment make it convenient for TV and music, while the horn provides a focused listening presentation. Erin called it his favorite Klipsch speaker. Measured bass extension of 42.5Hz (-3dB), with a measured sensitivity of 82.5dB.
Cons: The 6.90 ideal-subwoofer score reflects limitations beyond the narrow midband span. Horizontal coverage is relatively focused, so placement matters for multiple seats. The reviewer preferred reduced treble, and bass limiting at higher playback levels means the large woofer is not a guarantee of unlimited output. The app’s flat setting leaves treble elevated; Erin preferred a -2dB tweeter trim.

Neumann KH 310 A: $4,998 per pair B&H Photo Video eBay
Same family: the Neumann KH80 DSP (smaller bookshelf, rated 4.6/5), the Neumann KH120 MKII (smaller bookshelf, rated 4.7/5), the Neumann KH 150 (smaller bookshelf, ranked higher, rated 4.8/5), the Neumann KH420 (larger bookshelf, ranked higher, rated 4.8/5) and the Neumann KH 750 DSP (subwoofer, rated 3.5/5).
Pros: The sealed three-way design combines 35.2Hz measured -3dB extension with low distortion in the review’s demanding playback tests. Its 2.2dB response span from 300Hz to 5kHz and 7.70 ideal-subwoofer score support balanced monitoring with useful full-range capability. Measured bass extension of 35.2Hz (-3dB).
Cons: Its measured tonal balance is not as even as the KH 150 or the best coaxial alternatives. Correct orientation and listening height matter for the separated drivers. The analog system lacks the integrated calibration workflow of newer DSP models, so room correction requires additional equipment. An unexplained dip around 80Hz shows in the measurements.
