#30 Philharmonic BMR (v1): Current version: $2,200/pair Philharmonic Audio
Pros: 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.
Cons: 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.
How it compares: Just above it: ELAC VELA BS 403 - $699 more, 1.3Hz higher bass extension (-3dB). Just below it: Emotiva Airmotiv XB2 - $1651 cheaper, 3Hz higher bass extension (-3dB).
