KEF Q Concerto Meta vs Mission LX-3 MKII

Last updated: September 16, 2026

Short answer: the KEF Q Concerto Meta. It ranks #11 of 130 bookshelf speakers by sound quality; the Mission LX-3 MKII ranks #80.

KEF Q Concerto Meta vs Mission LX-3 MKII

What the KEF Q Concerto Meta offers: Really good in-room neutrality with consistent horizontal directivity from seat to seat. Directivity holds remarkably steady from lower treble into upper treble, where many similarly-priced speakers narrow sharply as frequency rises - one of the reviewer’s top 10 picks under $1,500. Watch for: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment. Needs to be pointed closer to on-axis rather than heavily toed out - combined with its rolled-off, shelved-down top end, too much toe-out makes it sound noticeably dark.

What the Mission LX-3 MKII offers: A large affordable standmount with a 6.5-inch woofer, 88dB rated sensitivity and useful bass. ASR measured 48Hz estimated in-room extension, a controlled Q of 0.60, a 5.52 subwoofer-assisted preference score and reasonable +/-55-degree horizontal coverage. Watch for: On-axis smoothness of 0.217 and predicted in-room smoothness of 0.344 reveal clear response unevenness, with a -0.46dB-per-octave downward tilt. The 345mm-tall, 8.4kg cabinet is bulky and current US availability is limited.
