Short answer: the Ascend Acoustics Sierra-2EX V2. It ranks #41 of 222 bookshelf speakers by sound quality, rated 4.3/5, at $1,748. The KEF Q3 Meta ranks #156, rated 3.4/5, at $764.97, $983.03 cheaper, which does not close the gap in sound quality.
The KEF Q3 Meta is the deeper-bass choice. Coaxial bookshelf speakers with very wide dispersion, punchy kick drums and bass tuning that works close to a wall. Its bass reaches about 52Hz before falling 3dB, against 58.6Hz for the Ascend Acoustics Sierra-2EX V2. The tradeoff: Not well suited to high-output use: compression and strain in the 1-2kHz region emerge above about 90dB at 10 feet, so a high-output home theater setup isn’t the best application.
The Ascend Acoustics Sierra-2EX V2 is the more accurate pick. A ribbon tweeter bookshelf speaker with hand matched pairs, a frequency response printout for each unit, and a long seven year warranty. Its measured preference score, a predictor of how neutral it sounds, is 5.88 against 4.66 for the KEF Q3 Meta. Watch for: On-axis response is relatively uneven, with an average deviation of about 0.45dB, so a listener sitting dead center may notice more unevenness than with smoother AsciLab or Ascend towers.
Buy the Ascend Acoustics Sierra-2EX V2. It is rated higher for sound quality, and the $983.03 you would save on the KEF Q3 Meta does not close the gap.
