Short answer: the Philharmonic BMR (v1) on measured sound quality, the Sonus Faber Lumina II Amator on price. The Philharmonic BMR (v1) ranks #36 of 130 bookshelf speakers at $2200. The Sonus Faber Lumina II Amator ranks #106 at $2000, $200 cheaper.
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.
What the Sonus Faber Lumina II Amator offers: Solid bass extension for a bookshelf (F3 63Hz, F10 43Hz), reaching about 50Hz in-room. Decent sensitivity and wide, consistent horizontal dispersion (~60-70 degrees) - better directivity than expected for a two-way design. Gorgeous, luxury-grade cabinet design. Watch for: Very bright treble, running 3-6dB above the midrange depending on measurement angle - independently corroborated by other owners online, not just one reviewer’s opinion. Causes audible sibilance and a forward, grainy character. Notably the brightest of three Sonus Faber models Erin’s Audio Corner has tested, even brighter than the brand’s own Sonetto II G2. A mechanical resonance/ringing artifact shows up around 1kHz in measurements. Needs a subwoofer for anything below about 50Hz.
Buy the Philharmonic BMR (v1) when sound quality outweighs the price for you, and the Sonus Faber Lumina II Amator when the price outweighs sound quality instead.
Skip the Sonus Faber Lumina II Amator if sound quality matters to you. It ranks near the bottom of the 130 bookshelf speakers.
