Paradigm Monitor SE 8000F vs Triangle Borea BR09

Short answer: the Paradigm Monitor SE 8000F. It ranks #172 of 226 floorstanding speakers by sound quality, rated 3.6/5, at $1,999.98. The Triangle Borea BR09 ranks #195, rated 3.3/5, at $1,850, $149.98 cheaper, a saving that is not big enough to make up the sound-quality gap.

The Paradigm Monitor SE 8000F is the better-sounding choice. Flagship Monitor SE tower with three 8-inch bass drivers and an 8-inch midrange delivering high 95dB in-room sensitivity and massive dynamic impact. Watch for: Substantial physical bulk and weight require ample room clearance.

What the Triangle Borea BR09 does well: Flagship Borea floorstander with triple 6.3-inch woofers producing deep bass extension to 35Hz and massive acoustic output for large listening rooms. The tradeoff: Large cabinet requires significant floor space and distance from room corners to avoid bass boom.

Buy the Paradigm Monitor SE 8000F. It is rated higher for sound quality, and the $149.98 you would save on the Triangle Borea BR09 does not close the gap.

About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Paradigm Monitor SE 8000F 3.4 to 3.8; Triangle Borea BR09 3.1 to 3.5). Treat this verdict as provisional.
