Short answer: the KEF Q Concerto Meta. It ranks #11 of 222 bookshelf speakers by sound quality, rated 4.6/5, at $999.99; the Triad In-Room Gold LCR ranks #203, rated 2.7/5, and costs $6,600, so there is little reason to consider the other one.
The KEF Q Concerto Meta is the more accurate choice. A neutral three way bookshelf speaker that sounds consistent from seat to seat, with smooth treble that many rivals at its price lack. Its measured preference score, a predictor of how neutral it sounds, is 6.01 against 4.04 for the Triad In-Room Gold LCR. The tradeoff: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
Why pick the Triad In-Room Gold LCR: A sealed three way home theater speaker with dual 8.5 inch woofers, very low distortion at high volume and broad coverage. The tradeoff: At $6600/pair, Erin found the raw response and value hard to defend without EQ: a 100-300Hz dip makes male vocals thin, a 1kHz dip adds hollowness, and a 4-5kHz rise makes sibilants harsh.
Buy the KEF Q Concerto Meta. It is rated higher for sound quality than the Triad In-Room Gold LCR and costs less, so only choose the other one for a particular feature it does better.
