Short answer: the Emotiva Airmotiv XB2, which is far easier to drive than the ELAC UBR62. The XB2 is very neutral and linear at its recommended toe-out angle, with better directivity than the similarly-priced ELAC Debut 3.0 DB63 and only a slight 2kHz upper-midrange recess. The UBR62 is a true three-way with a concentric 4-inch midrange and a dedicated 6.5-inch aluminum woofer, but Erin measured 83dB/2.83V/1m sensitivity and had to step up to a HINT 6 from his 110W Parasound.
Buy the Emotiva Airmotiv XB2. It is rated higher for sound quality than the ELAC Uni-Fi Reference UBR62 and costs less, which makes it the one to get unless you need something the other one does better.

Emotiva Airmotiv XB2: $549 per pair Emotiva eBay
Older models: the Emotiva B1+ (rated 4.1/5) and the Emotiva Airmotiv B2+ (ranked lower, rated 3/5).
Pros: Very neutral, linear frequency response at the recommended toe-out angle, with better directivity than the similarly-priced ELAC DB63. Decent bass extension for a bookshelf (F3 at 62Hz). AMT folded-ribbon tweeter with a rotating waveguide for placement flexibility. Great value: rated a top-three performer for the money by Erin’s Audio Corner. Measured bass extension of 62Hz (-3dB).
Cons: Slight recessed upper-midrange around 2kHz from the tweeter-to-woofer handoff. Sounds noticeably bright pointed directly at the listener: needs toeing out 10-20 degrees, crossfiring behind the head, for the most linear result. Elevated multi-tone distortion at higher output leads to some grainy, compressed mids when pushed. Irregular compression deviations affect dynamics at higher volume. Needs a subwoofer for real bass authority.

ELAC Uni-Fi Reference UBR62: $1,199 per pair Amazon eBay
Pros: True three-way stand-mount using a 1-inch tweeter concentrically mounted in a 4-inch aluminum midrange plus a dedicated 6.5-inch aluminum woofer. Erin found the directivity and overall tonality well controlled, with dual front slot vents minimizing placement sensitivity and cabinet bracing suppressing obvious coloration. The mostly 5-ohm-or-higher load is manageable for a genuinely 4-ohm-capable amplifier, and the coherent concentric upper range supports stable imaging across seats. Measured bass extension of 58.6Hz (-3dB), with a measured sensitivity of 83dB.
Cons: Erin measured very low 83dB/2.83V/1m sensitivity; his 110W Parasound was insufficient for the high-level test and the more powerful HINT 6 was needed. Impedance reaches 4 ohms near 50Hz (Erin), while woofer excursion and bass output were less capable than expected for the cabinet size. A broad 500-700Hz rise and associated lower/female-vocal coloration were audible, and the slightly subdued listening-window treble is necessary to avoid an overly bright in-room balance rather than evidence of ruler-flat axial tuning.
