Short answer: the Mission LX-3 MKII. It ranks #138 of 222 bookshelf speakers by sound quality (rated 3.6/5); the Triangle Borea BR03 ranks #198 (rated 2.8/5).
The Triangle Borea BR03 is the deeper-bass pick. A budget French bookshelf speaker with dual front ports, decent bass for the price and solid, well braced build quality. Its bass reaches about 57Hz before falling 3dB, against 67.4Hz for the Mission LX-3 MKII. 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 Mission LX-3 MKII is the better-sounding pick. Large affordable standmount speakers with a 6.5 inch woofer, useful bass and easy to drive sensitivity. The catch: On-axis smoothness of 0.217 and predicted in-room smoothness of 0.344 reveal clear response unevenness, with a -0.46dB-per-octave downward tilt.
Buy the Mission LX-3 MKII. It is rated higher for sound quality than the Triangle Borea BR03.
