What the KEF Q Concerto Meta does well: Really good in-room neutrality with consistent horizontal directivity from seat to seat. Watch for: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
What the Monolith Encore B6 does well: For its budget price, the B6 delivers useful midbass punch and a long reflex tail: Erin measured F3 at 68Hz and F10 near 37Hz. Watch for: Erin measured 85.3dB sensitivity and a 3.4-ohm minimum, so this is not an easy load despite its modest output ceiling.

The Two Speakers In Full
KEF Q Concerto Meta: $1,399.99 per pair Amazon Crutchfield eBay
Pros: 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. Measured bass extension of 53Hz (-3dB), with a measured sensitivity of 84.2dB.
Cons: 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.

Monolith Encore B6: $360 per pair Amazon Monoprice eBay
Pros: For its budget price, the B6 delivers useful midbass punch and a long reflex tail: Erin measured F3 at 68Hz and F10 near 37Hz. The revised tweeter assembly yields broadly smooth horizontal directivity and an early-reflections trend that accepts EQ well. At sane levels, its 6.5-inch pulp woofer provides satisfying attack, and gloss top/bottom panels plus a braced MDF cabinet are unusually substantial for the class. Measured bass extension of 68Hz (-3dB), with a measured sensitivity of 85.3dB.
Cons: Erin measured 85.3dB sensitivity and a 3.4-ohm minimum, so this is not an easy load despite its modest output ceiling. Low-frequency compression reaches about 2dB and distortion rises rapidly when driven full-range; use an 80Hz subwoofer crossover. Response variation is roughly +2.7/-3.7dB, with residual crossover/treble irregularities that keep it from true neutrality without EQ. The listening window tightens vertically, so ear height matters.
