Short answer: the Dynaudio Special Forty on measured sound quality, the Triangle Borea BR03 on price. The Dynaudio Special Forty ranks #148 of 222 bookshelf speakers, rated 3.5/5, at $3,600. The Triangle Borea BR03 ranks #198, rated 2.8/5, at $399, $3,201 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. The catch: 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 Dynaudio Special Forty is the more accurate option. Premium bookshelf speakers with strong output, wide dispersion and fairly deep bass from a compact rear ported cabinet. Its measured preference score, a predictor of how neutral it sounds, is 4.73 against 4.03 for the Triangle Borea BR03. The tradeoff: A glaring, sometimes sibilant quality around 3-4kHz was the most noticeable issue in listening, the one thing the reviewer would want notched out with EQ.
Buy the Triangle Borea BR03 when the price outweighs sound quality for you, and the Dynaudio Special Forty when sound quality outweighs the price instead.
