Short answer: the Dynaudio Heritage Special if sound quality matters most, the Sonus Faber Sonetto II G2 if price matters most. The Dynaudio Heritage Special ranks #28 of 130 bookshelf speakers at $7000. The Sonus Faber Sonetto II G2 ranks #103 at $3500, $3500 cheaper.
What the Sonus Faber Sonetto II G2 offers: Two-way design with a 1.125” damped Apex Dome silk tweeter and 6.5” cone woofer, using a base of concrete, aluminum, and steel with under-cabinet venting. Notably more neutral than Sonus Faber’s own Lumina 2, which runs 2-5dB hotter in the treble. Horizontal directivity narrows at a fairly constant, well-behaved rate rather than narrowing-then-widening-then-narrowing like some rivals (including the Lumina 2), meaning sidewall reflections match the direct sound well enough that the reviewer doesn’t recommend sidewall absorption for this speaker. The tweeter-to-woofer crossover handoff around 3kHz looks clean, suggesting a higher-order crossover than typical for the size/price class. Good dynamic range - the low end loses only about 2dB from 76dB to 96dB, otherwise holding up well. Not a difficult amplifier load (about 4.2 ohms minimum impedance). Bass extension reaches a genuine 50Hz in-room, fuller than the Lumina 2. Watch for: Sounds notably bright pointed directly on-axis; toeing the speaker out about 30° reduces treble energy and sibilance meaningfully. A resonance around 700Hz gives vocals a slightly nasal, hollow quality. A dip in the upper midrange (roughly 1-2kHz) reduces perceived detail and attack, while the elevated treble can read as “analytical” or “detailed” to some listeners despite being a coloration rather than true resolution. Needs more clearance from the rear wall than some rivals - about 1.5-2 feet in an ideal room, more or less depending on your specific room modes - or the 80-120Hz region can become boomy. Vertical listening window is limited to about ±10-15° from the tweeter axis. Some unexplained directivity irregularities appear around 1.2kHz and 1.6kHz, possibly port-related, along with a longer decay in the 800Hz-1600Hz range in burst-decay measurements. Multitone distortion approaches the reviewer’s 3% threshold through the midrange, though likely not obviously audible without direct A/B comparison. A resonance in the cabinet appears around 400Hz in impedance measurements.
What the Dynaudio Heritage Special offers: One of the rare cases where the reviewer measured a speaker as flawed but still genuinely enjoyed listening to it. A massive 4” voice coil on the midwoofer gives it exceptional output capability for a bookshelf speaker - averaged 100dB at 3.5 meters with no audible mechanical noise, port chuffing, or woofer bottoming even when deliberately pushed hard. Bass is very robust and doesn’t noticeably give up output as volume increases, staying solid at both low and high listening levels. Big, well-proportioned soundstage - wide without losing image focus. Limited run of 2,500 pairs with genuine collectible/heritage value; the tweeter (Esotar 3) and midwoofer both use premium Dynaudio-made drivers with an unusually wide, stout voice coil. Watch for: At lower listening volumes, dynamic range and kick-drum punch fell short of higher-sensitivity speakers the reviewer has tested (JBL 4367, KEF Reference 1 Meta) - the sheer output ceiling is impressive, but it isn’t a highly dynamic-sounding speaker at modest levels. A degree of “softness” in the upper mid-range. Selective sibilance in the 4-6kHz treble region that shows up on some tracks but not others, which the reviewer found mildly aggravating and would want to EQ down given the choice. Neither the tweeter nor the woofer is fully flush-mounted to the baffle, likely intentional as part of the heritage-styled look, but the reviewer wonders how much this affected linearity. At $7,000/pair MSRP (and a discontinued limited run, so used/open-box pricing around $5,000/pair is about the best you’ll do now), this is a serious investment for a bookshelf speaker.
Buy the Sonus Faber Sonetto II G2 when the price outweighs sound quality for you, and the Dynaudio Heritage Special when sound quality outweighs the price instead.
The Sonus Faber Sonetto II G2 is not a sound-quality pick. It sits near the bottom of the 130 bookshelf speakers; there are better options higher up.
