Short answer: the GR-Research LGK 2.0, though neither ranks well in its class. It ranks #117 of 168 bookshelf speakers by sound quality, rated 2.8/5, at $290; the Triangle Borea BR02 ranks #119, rated 2.7/5, and costs $299, so there is not much of a tradeoff to weigh. Both are rated below 3.0/5 among the 168 bookshelf speakers, so if sound quality matters, consider the Ascend Acoustics HTM-200SE2 instead, ranked #7 at $368.
Why pick the GR-Research LGK 2.0: A small kit speaker from GR Research built around a single 3” wide-band driver, sold as a kit or flat-pack for desktops and near-field listening. The tradeoff: Sensitivity is low at 84dB.
Why pick the Triangle Borea BR02: Compact 2-way standmount design well suited for tight desktop setups or small rooms. The catch: Shares the series upper-midrange dip and energetic mid-treble, resulting in lean vocal presentation and sibilance on bright recordings.
Buy the GR-Research LGK 2.0. It is rated higher for sound quality than the Triangle Borea BR02 and costs less, which makes it the one to get unless you need something the other one does better.
About the ratings: the Triangle Borea BR02’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 2.5 to 2.9, so this verdict could change once it is measured.

Triangle Borea BR02: $299.00 per pair Estimated Amazon eBay
Same family: the Triangle Borea BR03 (larger bookshelf, rated 2.8/5), the Triangle Borea BR04 (larger bookshelf, estimated 3/5), the Triangle Borea BR07 (smallest floorstanding, estimated 3/5), the Triangle Borea BR08 (floorstanding, estimated 3.2/5), the Triangle Borea BR09 (floorstanding, estimated 3.3/5), the Triangle Borea BR10 (largest floorstanding, estimated 3.3/5), the Triangle Borea BRC01 (smaller center, estimated 3.4/5) and the Triangle Borea BRC2 (larger center, estimated 3.3/5).
Pros: Compact 2-way standmount design well suited for tight desktop setups or small rooms. High sensitivity of 89dB allows it to reach good volume levels with modest amplifier power. Wide high-frequency dispersion creates an open, expansive soundstage.
Cons: Shares the series upper-midrange dip and energetic mid-treble, resulting in lean vocal presentation and sibilance on bright recordings. Low-frequency extension is limited with bass rolling off above 51Hz, and minimum impedance drops to 3.6 ohms.
