WHY THE PRICE IS JUSTIFIED

The pair price buys matched amplifiers, DSP crossover/limiting, a carefully controlled waveguide and calibration capability—not passive-speaker jewelry. Sound On Sound describes its response as perhaps the flattest it has measured and calls its distortion notable.

MATERIALS

CabinetLow-resonance injection-molded composite

Controls enclosure vibration without wasting volume.

Woofer6.5-inch long-throw driver

Active DSP limits excursion while allowing clean low-frequency extension.

TweeterTitanium-fabric dome

Supports low-resonance high-frequency output.

CRITERIA

10/10
Smooth VoicingSound On Sound calls it probably the flattest response it has measured on a commercial speaker.
10/10
Even DispersionThe MMD waveguide provides controlled off-axis behavior.
10/10
Low DistortionIndependent measurements highlight notably low distortion; DSP manages driver stress.
9/10
Bass ControlIt reaches about 39 Hz (-3 dB) with DSP excursion management.
9/10
Driver IntegrationDSP crossover filters provide controlled phase and a seamless handoff.
9/10
Solid CabinetLow-resonance molded enclosure is designed as an inert professional tool.
10/10
Easy LoadAmplifiers are built in; MA 1 calibration also reduces room/placement fuss.

IDEAL FOR

  • ·Nearfield or midfield critical listening
  • ·Small-to-medium rooms
  • ·Users willing to use active speakers and room alignment

NOT FOR

  • ·Those requiring a passive amp/speaker system
  • ·Very large rooms at cinema SPL

DESIGN & ERGONOMICS

Compact, sober professional design rather than decorative furniture. Its small footprint and optional MA 1 alignment are genuinely ergonomic advantages in normal rooms.

LONGEVITY

Professional product line with firmware and service support; active electronics are less DIY-repairable than passive speakers, but Neumann has an established global service network.
