Short answer: the Dynaudio Heritage Special if sound quality matters most, the Philharmonic BMR Monitor if price matters most. The Dynaudio Heritage Special ranks #28 of 130 bookshelf speakers at $7000. The Philharmonic BMR Monitor ranks #76 at $2200, $4800 cheaper.
What the Philharmonic BMR Monitor offers: Three-way design combining a 6” SB Acoustics mid-woofer, a 2.5” Tectonic balanced-mode radiator (BMR) for the midrange, and a ribbon tweeter - premium component choices relative to the asking price. A clear improvement over the V1: the earlier version’s overly hot, plateauing treble has been resolved, leaving a genuinely good in-room response outside of one specific area. Extremely wide horizontal radiation of about ±70-80°, creating an enveloping, wide soundstage that illuminates the sidewalls. Well-built, attractive cabinet. Midrange and tweeter show no stress or elevated distortion even at higher output - all the compression and distortion issues trace back to the mid-woofer alone. Watch for: A 1-2dB bump around 2-3kHz creates a “glare” on vocals, guitars, and strings that the reviewer noticed consistently across many tracks. The extremely wide radiation trades off against imaging precision - instrument placement became noticeably more diffuse and harder to pinpoint in a narrower, more reflective room, though it improved substantially in a larger, more open room with less sidewall interaction. A suspected resonance around 500Hz shows up as an imbalance in sound power and horizontal directivity measurements, loosely correlating with a vague sense of resonance the reviewer heard subjectively. Moderate sensitivity (about 84.1dB anechoic) and a mid-woofer that runs out of steam under real stress - distortion exceeds 3% even at 100Hz at 96dB, and the reviewer notes SB Acoustics’ published excursion specs tend to overstate real-world linear excursion by nearly 2x. Significant compression appears at 102dB: the woofer audibly unloads around 120Hz, and the ribbon tweeter also compresses heavily at high output - not well suited to very loud two-channel listening (above about 90dB at 4 meters). In-room bass rolls off around 50Hz, so a subwoofer is recommended for most music. Benefits noticeably from a few bands of EQ if available.
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 Philharmonic BMR Monitor when the price outweighs sound quality for you, and the Dynaudio Heritage Special when sound quality outweighs the price instead.
