Pros: Two-way design with a 28mm Esotar soft dome tweeter (Hexis-damped) and an 18cm mid-woofer, using a first-order crossover on the tweeter and second-order on the woofer. Exceptional bass extension for a bookshelf speaker: reaches a clean, authoritative 40Hz in-room, rare enough that the reviewer says most listeners could skip a subwoofer for typical music. Very low distortion across the board, staying below 1% THD down to 40Hz at 86dB and below 3% even at 96dB: unusually clean bass performance where most two-way bookshelf speakers start rising in distortion around 80Hz. Wide, remarkably consistent horizontal directivity (about ±50-60°) that holds steady up to roughly 13kHz: rare for a speaker in this format, thanks to a beveled tweeter edge that acts as a mild waveguide. Excellent compression and dynamic-range linearity at the frequency extremes, actually showing slight bass enhancement rather than the sharp low-end compression common in similarly-sized bookshelf speakers. Measured bass extension of 54Hz (-3dB), with a measured sensitivity of 83.5dB.

Cons: A resonance around 600-800Hz gives snares and similar percussion a muffled, flat quality lacking impact: confirmed as originating in the woofer itself (isolated via measurements of the raw driver out of the cabinet), and attempts at constrained-layer damping didn’t resolve it. A peak around 4kHz adds a sharp, edgy quality to some male vocals. A roughly 5dB boost above 10kHz gives cymbals and hi-hats excess shimmer that can sound unnatural, especially pointed directly on-axis. Vertical dispersion shows two separate crossover-related notches (above and below the tweeter reference line around 5kHz) rather than the usual single one, a direct consequence of the shallow crossover slopes used on both drivers. Multitone distortion is elevated in the midrange, possibly due to the woofer’s magnet structure lacking a shorting ring. Best aimed slightly off-axis (about 10-15° of toe-out) to tame the excess high-frequency shimmer, rather than pointed straight at the listener.

Pros: Smooth, “buttery” overall tonal character consistent with Dynaudio’s house sound. Surprisingly precise, focused imaging despite wide horizontal radiation (about ±70°): atypical, since wide-radiating speakers usually sacrifice some image precision in reflective rooms. Strong output capability: reached 100-101dB average at 3.5 meters with no audible distortion or woofer distress, and compression testing at 102dB shows the cabinet holding up mechanically well at extreme output. Bass reaches a genuine 50Hz (potentially 40Hz) in most rooms from a rear-ported design. Distortion stays below 1% at 86dB and doesn’t cross 3% THD until about 50Hz even at 96dB. Extra weight and impact on snares and percussion around 700-800Hz that the reviewer found appealing on many tracks. Measured bass extension of 54Hz (-3dB), with a measured sensitivity of 83.5dB.

Cons: A glaring, sometimes sibilant quality around 3-4kHz was the most noticeable issue in listening, the one thing the reviewer would want notched out with EQ. Multiple enclosure resonances appear between 500Hz-1kHz across on-axis, listening window, early-reflections, and sound-power measurements, corroborated by independent third-party CSD data showing similar 500-800Hz cabinet resonances. A dip around 1.2kHz traces to a cone-edge-to-surround compliance mismatch in the driver itself (confirmed by testing the bare driver’s impedance): a known artifact common to many similarly-sized drivers across several manufacturers, contributing to elevated second-order distortion in that region. A somewhat laid-back, recessed 1-2kHz character (sometimes described as a “BBC dip”) gives an overall subdued quality that isn’t overtly problematic but shapes the tonal balance. Impedance drops below 3 ohms in the 100-200Hz region, requiring a genuinely 4-ohm-stable amplifier rather than an AVR. Rear port means it can’t be placed directly against a wall.
