Short answer: the Neumann KH420 for better sound quality, the Klipsch The Sevens for the lower price. The Neumann KH420 ranks #4 of 66 powered bookshelf speakers at $10500. The Klipsch The Sevens ranks #58 at $999.99, $9500.01 cheaper.
What the Neumann KH420 offers: CEA2034 spinorama shows an extended, flat on-axis response that matches Neumann’s own published measurement to within 0.08dB at its one minor dip (around 60Hz), with excellent off-axis behavior. Predicted in-room response is smooth and rated “excellent” by the reviewer. Horizontal beamwidth of about ±55 degrees is very well controlled and stays consistent across frequency. Distortion is low at 86dB SPL/1m. Exceptionally high sustained output capability - the reviewer needed to “hold on for dear life” during extreme-level testing at 7 feet, with bass output described as making the entire house resonate. Reviewer’s overall verdict was “Great,” placing it on the recommended list and calling it a speaker “you could buy and forget about upgrading ever again.” Watch for: Horizontal beamwidth, while well controlled, is on the narrow side at about ±55 degrees. Vertical directivity is more limited than horizontal - the reviewer recommends staying within about ±30 degrees of the reference axis (just below the tweeter waveguide edge). Distortion rises noticeably in the bass region at 96dB SPL/1m, with an unusual 3rd-harmonic uptick appearing near 10kHz at that output level. At 106dB SPL/1m, the tweeter’s protection limiting engages and the clipping indicator activates - a real, measurable output ceiling despite the speaker’s otherwise very high capability. Very expensive.
What the Klipsch The Sevens offers: Genuinely good bass - reaches about 40 Hz in-room with a solid, controlled thump and no real strain, backed by measured extension to F3 49Hz/F10 36Hz. “Wireless” design only requires one power outlet: a single signal cable runs from the primary speaker to the secondary, so only the primary needs a power cable. Extensive inputs - HDMI, phono, 3.5mm, USB, optical, plus Bluetooth. Companion app exposes treble/mid/bass adjustment, subwoofer output, and a dynamic bass mode, giving real tuning flexibility. Good linearity overall once EQ’d - dropping the treble by 1-2dB got the reviewer to a more satisfying tonal balance. Watch for: Notably narrower horizontal radiation than its stablemate, the Klipsch The Nines, meaning less favorable room interaction and a smaller sweet spot - the reviewer suspects this is a meaningful part of why he preferred the Nines. Out of the box (flat EQ), the top end is a bit too lifted/bright. A persistent dip in the upper mid-range (2-4kHz) that the reviewer found dull and lifeless regardless of EQ tweaking to the treble control - he felt this region specifically needed better tuning from Klipsch, not just a treble slider adjustment. Response isn’t quite flat even after adjustment - there’s peaking up around 8kHz that reinforces a scooped-sounding in-room balance at the listening seat.
Buy the Neumann KH420 if sound quality matters more than the price. Buy the Klipsch The Sevens if the price matters more than sound quality.
If sound quality matters at all to you, skip the Klipsch The Sevens. It ranks near the bottom of the 66 powered bookshelf speakers, so look higher up the list instead.
