Short answer: the Philharmonic BMR Monitor if sound quality matters most, the Triangle Borea BR03 if price matters most. The Philharmonic BMR Monitor ranks #134 of 222 bookshelf speakers, rated 3.6/5, at $2,200. The Triangle Borea BR03 ranks #198, rated 2.8/5, at $399, $1,801 cheaper.
The case for the Triangle Borea BR03: A budget French bookshelf speaker with dual front ports, decent bass for the price and solid, well braced build quality. The tradeoff: A noticeable mid-range suckout, most pronounced in the upper mid-range/lower treble, that the reviewer attributes to cabinet resonances and driver breakup rather than a deliberate voicing choice: it makes vocals and instruments sound recessed and thin rather than warm.
The Philharmonic BMR Monitor is the more accurate, deeper-bass pick. Three-way bookshelf speakers with premium drivers, a well-built cabinet and extremely wide dispersion for a broad soundstage. Its measured preference score, a predictor of how neutral it sounds, is 6.02 against 4.03 for the Triangle Borea BR03. Its bass reaches about 47Hz before falling 3dB, against 57Hz for the Triangle Borea BR03. The tradeoff: A 1-2dB bump around 2-3kHz creates a “glare” on vocals, guitars, and strings that the reviewer noticed consistently across many tracks.
Buy the Triangle Borea BR03 when the price outweighs sound quality for you, and the Philharmonic BMR Monitor when sound quality outweighs the price instead.
