Short answer: the Klipsch RP-600M II. It ranks #124 of 222 bookshelf speakers by sound quality, rated 3.7/5, at $449.99; the Triangle Borea BR04 ranks #191, rated 3.0/5, and costs $649, which makes this an easy call rather than a real tradeoff.
The Klipsch RP-600M II is the better-sounding option. Redesigned waveguide extends flush to the baffle edge, reducing diffraction compared to the original Klipsch RP-600M. The catch: On-axis, the treble runs notably hot (even hotter than the original Klipsch RP-600M in some respects) and needs about 20° of toe-out or the grille installed to sound balanced.
Why pick the Triangle Borea BR04: A larger Triangle Borea BR03 with a 6.3” cellulose woofer and a front port, rated from 44Hz at 90dB, so it is easy to drive and can sit near a wall. Watch for: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
Buy the Klipsch RP-600M II. It is rated higher for sound quality than the Triangle Borea BR04 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
About the ratings: the Triangle Borea BR04’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 2.7 to 3.3, so this verdict could change once it is measured.
