Short answer: the KEF R3 Meta. It ranks #10 of 131 bookshelf speakers by sound quality, rated 4.6/5, at $2,499.99; 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 R3 Meta: Three-way design with an unconventional concentric layout: the 1” tweeter is recessed into the throat of the 5.25” midrange driver, deeper integration than a standard coaxial arrangement. Watch for: Pointed straight on-axis, there’s a 1-2dB bump around 9kHz that stays consistent across angles thanks to the constant-directivity waveguide - only toeing the speaker out about 10° tames it.
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 R3 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.

Pros: Three-way design with an unconventional concentric layout: the 1” tweeter is recessed into the throat of the 5.25” midrange driver, deeper integration than a standard coaxial arrangement. A quasi sealed/ported bass alignment gives an extended low-end shelf tuned to match typical in-room gain, reaching about 50Hz for most content - deeper than recently-tested rivals like the Focal Aria 906, Polk R200, and an 8” Aperion design. Spinorama measurements show class-leading directivity and sound power, plus very linear on-axis response (at the recommended 10° toe-out) and early-reflections directivity, so it takes EQ exceptionally well. The vertical sweet spot extends to about ±20-30° off the reference axis with nearly identical tonality, unusually wide for a two- or three-way design. A clear upgrade over the earlier, non-Meta R3, eliminating the treble brightness the original had even when toed off-axis. Outperforms similarly-priced rivals (Revel M106, Wharfedale Linton, Philharmonic BMR V2, JBL HDI 1600) specifically on directivity and linearity in the reviewer’s measurements. At $2500/pair, called the best value in its class with near-reference-level anechoic performance. Measured bass extension of 76Hz (-3dB), with a measured sensitivity of 85.9dB.
Cons: Pointed straight on-axis, there’s a 1-2dB bump around 9kHz that stays consistent across angles thanks to the constant-directivity waveguide - only toeing the speaker out about 10° tames it. Minimum impedance dips to about 3.2 ohms nominal (EPDR as low as 1.9 ohms), so it needs a 4-ohm-stable amplifier; a standard AVR likely won’t cut it. Distortion crosses the reviewer’s 3% threshold around 80Hz at 96dB output and shows added deviation again near 50Hz, indicating it runs out of headroom at higher volumes - a subwoofer is recommended for loud listening. Horizontal radiation narrows from about ±70° at low frequency to ±40° at high frequency. Below about 100Hz, compression testing shows fairly wide deviations at both 86dB and 96dB output, though the reviewer notes this is typical for speakers in this size and price class. Current R3 owners who are already happy with that speaker have little reason to upgrade.

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.
