Short answer: the ELAC Uni-Fi 2.0 UB52 on measured sound quality, the Klipsch R-41M on price, though neither ranks well in its class. The ELAC Uni-Fi 2.0 UB52 ranks #130 of 160 bookshelf speakers, rated 2.4/5, at $599. The Klipsch R-41M ranks #158, rated 1.3/5, at $141.55, $457.45 cheaper. Both are rated below 3.0/5 among the 160 bookshelf speakers, and the Ascend Acoustics HTM-200SE2, ranked #7 at $368, is a better place to start if sound quality matters.
The ELAC Uni-Fi 2.0 UB52 is the more accurate, deeper-bass pick. Wide, smooth horizontal directivity: beamwidth holds to about ±60 degrees up to 8kHz before narrowing. Its measured preference score, a predictor of how neutral it sounds, is 5.32 against 3.04 for the Klipsch R-41M. Its bass reaches about 55.7Hz before falling 3dB, against 80Hz for the Klipsch R-41M. Watch for: Dipped 3db from 1.5-3kHz.
Why pick the Klipsch R-41M: Binding posts are unusually nice for the price point, and impedance is well controlled in the bass, easing the load on the amplifier. The tradeoff: CEA2034 spinorama shows a sharp, prominent peak around 1kHz that the reviewer compared to “Pinocchio’s nose,” plus poor directivity that makes the off-axis sound diverge sharply from on-axis.
Buy the ELAC Uni-Fi 2.0 UB52 if sound quality is the priority over the price, or the Klipsch R-41M if the price is the priority over sound quality.

ELAC Uni-Fi 2.0 UB52: $599.00 per pair Amazon eBay
Same family: the ELAC Uni-Fi 2.0 UF52 (floorstanding, estimated 4.2/5) and the ELAC Uni-Fi 2.0 UC52 (center, rated 3.9/5).
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.

Klipsch R-41M: $141.55 per pair Amazon eBay
Newer model: the Klipsch Reference R-40M, ranked higher, estimated 1.4/5.
Same family: the Klipsch R-51M (larger bookshelf, ranked higher, rated 1.6/5).
Pros: Binding posts are unusually nice for the price point, and impedance is well controlled in the bass, easing the load on the amplifier. The horn-loaded tweeter can play loud without strain. Measured bass extension of 80Hz (-3dB), with a measured sensitivity of 85dB.
Cons: CEA2034 spinorama shows a sharp, prominent peak around 1kHz that the reviewer compared to “Pinocchio’s nose,” plus poor directivity that makes the off-axis sound diverge sharply from on-axis. Sensitivity is only 85dB through most of the music-energy range despite Klipsch’s horn-loaded reputation for efficiency. In an A/B against a $118/pair Pioneer SP-BS22-LR, the R-41M had “no bass” and all mid-to-treble energy; the reviewer’s verdict was “please avoid the Klipsch R-41M unless you just want a speaker as an ornament.”
