Short answer: the Philharmonic BMR (v1). It ranks #36 of 130 bookshelf speakers by sound quality at $2200; the Sonus Faber Sonetto II G2 ranks #103 and costs $3500, which makes this an easy call rather than a real tradeoff.
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 Philharmonic BMR (v1) offers: Large three-way combining a Scan-Speak 7-inch paper/carbon woofer, 2.5-inch Tectonic balanced-mode midrange and RAAL 64-10 ribbon. Erin measured approximately +/-1.5dB linearity from 80Hz upward, very broad +/-40-degree-or-better horizontal coverage and about 83dB/2.83V/1m sensitivity. The port is tuned in the mid/low-30Hz region without audible chuffing, the midrange provides unusually expansive staging, and distortion remained subjectively unobtrusive. Watch for: The measured 83dB sensitivity and roughly 4-ohm load demand meaningful external amplification. A 1-2dB shelf below about 300Hz reduces warmth unless corrected, while a response/impedance feature near 250-300Hz corresponded with Erin’s sense of resonance. The ribbon produces narrower vertical than horizontal radiation, and second-order high-frequency distortion plus dynamic enhancement near 3kHz appeared in testing. This was an earlier cabinet/version, not the current v2.
Buy the Philharmonic BMR (v1). It ranks higher for sound quality than the Sonus Faber Sonetto II G2 and costs less, so there is no real case for the other one.
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.
