Short answer: the Revel M105 for better sound quality, the ELAC Uni-Fi 2.0 UB52 for the lower price. The Revel M105 ranks #12 of 74 bookshelf speakers at $1500. The ELAC Uni-Fi 2.0 UB52 ranks #55 at $599, $901 cheaper.
What the ELAC Uni-Fi 2.0 UB52 offers: 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. Watch for: 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.
What the Revel M105 offers: CEA2034 spinorama shows an essentially flat on-axis response with only a small 5kHz peak, a smooth listening window, and clean waterfall decay. Wide horizontal dispersion gives flexibility with toe-in. The reviewer called it reference-quality performance with minor EQ correction applied. Watch for: Low nominal impedance demands a capable amplifier that can handle low-impedance loads. Bass distortion runs high in the 80-250Hz range from woofer displacement, and maximum output is limited compared to larger designs.
Buy the ELAC Uni-Fi 2.0 UB52 if the price matters more than sound quality. Buy the Revel M105 if sound quality matters more than the price.
