Short answer: the Philharmonic BMR (v1) on measured sound quality, the Emotiva Airmotiv XB2 on price. The Philharmonic BMR (v1) ranks #36 of 130 bookshelf speakers at $2200. The Emotiva Airmotiv XB2 ranks #40 at $549, $1651 cheaper.
What the Emotiva Airmotiv XB2 offers: Very neutral, linear frequency response at the recommended toe-out angle, with better directivity than the similarly-priced ELAC DB63. Decent bass extension for a bookshelf (F3 at 62Hz). AMT folded-ribbon tweeter with a rotating waveguide for placement flexibility. Great value - rated a top-three performer for the money by Erin’s Audio Corner. Watch for: Slight recessed upper-midrange around 2kHz from the tweeter-to-woofer handoff. Sounds noticeably bright pointed directly at the listener - needs toeing out 10-20 degrees, crossfiring behind the head, for the most linear result. Elevated multi-tone distortion at higher output leads to some grainy, compressed mids when pushed. Irregular compression deviations affect dynamics at higher volume. Needs a subwoofer for real bass authority.
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.
