Neumann KH80 DSP vs Adam Audio A4V

Last updated: August 25, 2026

Short answer: the Neumann KH80 DSP. It ranks #7 of 64 powered bookshelf speakers by sound quality at $598.98; the Adam Audio A4V ranks #48 and costs $599.99, so there is not much of a tradeoff to weigh.

What the Neumann KH80 DSP offers: Compact 2-way nearfield monitor - a 1” tweeter in an elliptical waveguide over a 4” mid-woofer, crossed over around 1.8kHz with steep 48dB/octave slopes. Exceptionally linear on-axis response, within about ±1.5dB, with essentially nothing worth equalizing beyond a minor, likely port-related wrinkle around 800Hz. Vertical dispersion is unusually wide and consistent for a monitor this size, holding together to roughly ±40° versus the ±20° or so typical of similarly compact designs - a benefit of the steep crossover slopes and waveguide minimizing comb filtering, so listening height and seating posture matter less than on most small monitors. Back-panel switches (freestanding, small/medium/large desk) tailor the low-mid response to compensate for desk-boundary reflections. Distortion in the midrange doesn’t change when high-passed to a subwoofer at 80Hz, showing the drivers already have a clean distortion profile on their own. Maintains good composure and linearity up to about 96dB SPL down to roughly 80Hz before an active protection circuit engages; tested with dense multitone program material rather than a sine sweep, output around 96dB costs only about 1dB in the midrange, putting realistic maximum SPL near 95dB. Watch for: High price for its size, at roughly $1,000/pair. The horizontal pattern stays wide and essentially constant out to about ±30° before beaming and narrowing further out (then flattening again near 2kHz) - a wide, controlled pattern in absolute terms, but one that reflects more high-frequency energy off nearby sidewalls than a narrower design would. At greater listening distances or in more reflective rooms (tested around 6 feet away at 75-80dB), that shows up as a top end that reads a bit hot despite the speaker measuring essentially flat on-axis - a byproduct of its directivity rather than its tonal balance, and mostly moot for genuine nearfield desktop use inside about a meter. The estimated in-room response shows a shallow dip around 1-2kHz and a treble trend running 2-3dB above the midrange in that same far-field estimate. Multitone distortion for a single speaker climbs into the 3-5% range at 96dB SPL, though that’s only really relevant well above typical nearfield listening levels. Bass rolls off below its F3 of 57Hz (F10 48Hz), so the 4” mid-woofer still needs a subwoofer for real low-end content. The companion app for EQ/setup is iPad-only, with no Android or Bluetooth option despite being control-only, and the in-room calibration microphone is a separate purchase in most cases. In a separate comparison test, the smoother-measuring KH80 actually sounded smaller and less present than the cheaper JBL 305P MKII, which had more perceived bass and clarity despite measuring worse on paper.

What the Adam Audio A4V offers: Compact current-generation monitor with an X-ART tweeter, onboard DSP, room controls and Sonarworks integration. ASR data shows good on-axis smoothness (0.132), a nearly neutral +0.23dB/octave slope and a 5.43 preference score with a subwoofer. Watch for: Measured bass extension is only 52Hz and the raw preference score falls to 3.02 without a subwoofer. Directivity-index consistency is middling at 3.77, and its analog-only XLR/RCA audio inputs omit USB and S/PDIF.

Buy the Neumann KH80 DSP. It ranks higher for sound quality than the Adam Audio A4V and costs less, so there is no real case for the other one.

If sound quality matters at all to you, skip the Adam Audio A4V. It ranks near the bottom of the 64 powered bookshelf speakers, so look higher up the list instead.
