Short answer: the Buchardt Audio E50 if sound quality matters most, the Triangle Borea BR03 if price matters most. The Buchardt Audio E50 ranks #16 of 222 bookshelf speakers, rated 4.5/5, at $4,600. The Triangle Borea BR03 ranks #198, rated 2.8/5, at $399, $4,201 cheaper.
What the Triangle Borea BR03 does well: A budget French bookshelf speaker with dual front ports, decent bass for the price and solid, well braced build quality. Watch for: 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 Buchardt Audio E50 is the more accurate, deeper-bass option. A bookshelf speaker with remarkably deep bass for its size, a very neutral midrange, and low distortion, with no need to sit near a wall. Its measured preference score, a predictor of how neutral it sounds, is 5.84 against 4.03 for the Triangle Borea BR03. Its bass reaches about 40Hz before falling 3dB, against 57Hz for the Triangle Borea BR03. The tradeoff: A roughly 3dB dip in the upper midrange/lower treble softens attack and dialogue clarity: the reviewer’s main complaint, and it’s baked into the crossover rather than a directivity artifact, so it’s audible both on and off axis.
Buy the Triangle Borea BR03 if the price is the priority over sound quality, or the Buchardt Audio E50 if sound quality is the priority over the price.
