Short answer: the Wharfedale Diamond 220. It ranks #27 of 71 bookshelf speakers by sound quality at $350; the ELAC Uni-Fi 2.0 UB52 ranks #52 and costs $599, so there is not much of a tradeoff to weigh.
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 Wharfedale Diamond 220 offers: Amir found the on-axis response smooth once the grille is removed, calling grille removal “a huge improvement” since the stock grille caused unusually strong comb filtering around 5kHz. Good horizontal dispersion from the waveguide-loaded tweeter and controlled distortion. After some EQ (a room mode filter and treble shelf), the reviewer called it “a truly hifi speaker” where “every audiophile track…sounded very good,” and said he was “happy to recommend” it for the budget class. Watch for: Response rolls off below 200Hz, so a subwoofer is recommended for full-range use. Some port rattling was noted at high volumes, traced to vibration rather than the woofer itself. Best performance requires removing the grille and applying the reviewer’s EQ filters.
Buy the Wharfedale Diamond 220. It ranks higher for sound quality than the ELAC Uni-Fi 2.0 UB52 and costs less, so there is no real case for the other one.
