Short answer: the KEF Q Concerto Meta. It ranks #11 of 131 bookshelf speakers by sound quality, rated 4.6/5, at $1,399.99; the JBL 708i ranks #72, rated 3.7/5, and costs $3,198, so there is not much of a tradeoff to weigh.
The case for the KEF Q Concerto Meta: 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.
The case for the JBL 708i: High-output 8-inch professional monitor with JBL’s compression driver and Image Control Waveguide. The tradeoff: This is not self-powered: achieving the measured active-mode response requires compatible external amplification and JBL processing, adding substantial cost and complexity.
Buy the KEF Q Concerto Meta. It is rated higher for sound quality than the JBL 708i and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

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.

JBL 708i: $3,198 per pair B&H Photo Video eBay
Pros: High-output 8-inch professional monitor with JBL’s compression driver and Image Control Waveguide. In JBL’s intended bi-amplified Crown DCI/DSP configuration, ASR data shows 39Hz extension, controlled roughly +/-50-degree horizontal coverage and a 6.21 preference score with a subwoofer. Measured bass extension of 43.9Hz (-3dB).
Cons: This is not self-powered: achieving the measured active-mode response requires compatible external amplification and JBL processing, adding substantial cost and complexity. On-axis smoothness (0.241), predicted in-room smoothness (0.198) and a 4.33 raw preference score are modest for the system price.
