Short answer: the JBL Stage 250B. It ranks #52 of 88 bookshelf speakers by sound quality, rated 3.2/5, at $439.95; the ELAC Uni-Fi 2.0 UB52 ranks #68, rated 2.4/5, and costs $599, so there is not much of a tradeoff to weigh.
The case for the JBL Stage 250B: Good local Spinorama scores of 4.06 raw and 6.60 with a subwoofer, with smooth horizontal directivity from JBL’s next-generation HDI waveguide. Watch for: Its objective score is good rather than class-leading, and the rear port needs some wall clearance.
What the ELAC Uni-Fi 2.0 UB52 does well: Wide, smooth horizontal directivity - beamwidth holds to about ±60 degrees up to 8kHz before narrowing. The catch: Dipped 3db from 1.5-3kHz.
Buy the JBL Stage 250B. It is rated higher for sound quality than the ELAC Uni-Fi 2.0 UB52 and costs less, which makes it the one to get unless you need something the other one does better.

JBL Stage 250B: $439.95 per pair Amazon JBL eBay
Older model: the JBL Stage A130 (ranked lower, rated 2.1/5).
Pros: Good local Spinorama scores of 4.06 raw and 6.60 with a subwoofer, with smooth horizontal directivity from JBL’s next-generation HDI waveguide. The current Stage 2 model offers solid build details, magnetic grilles and useful 56Hz measured extension at an accessible price. Measured bass extension of 64.5Hz (-3dB).
Cons: Its objective score is good rather than class-leading, and the rear port needs some wall clearance. At 86dB sensitivity and six-ohm nominal impedance it is not especially easy to drive, while the compact woofer limits deep-bass output.

ELAC Uni-Fi 2.0 UB52: $599.00 per pair Amazon eBay
Pros: Wide, smooth horizontal directivity - beamwidth holds to about ±60 degrees up to 8kHz before narrowing. Vertical directivity is substantially better than average, giving more listening-height leeway than most two-way bookshelf speakers. Measured bass extension of 55.7Hz (-3dB), with a measured sensitivity of 83.3dB.
Cons: Dipped 3db from 1.5-3kHz. On-axis response shelves down above 1.5kHz along with multiple resonances, leading the reviewer to predict it will “likely sound dull.” Nasty resonance at 600Hz - audible as an actual buzzing artifact on some recordings (the reviewer demonstrated it with an Eva Cassidy track), and it shows up as a sharp distortion spike exceeding 4% at 585Hz when driven to 96dB SPL/1m. Not recommended.
