Short answer: a tie on sound quality. Both are rated 4.5/5 (#15 and #19 of 222 bookshelf speakers), so choose on features and fit.
What the KEF R3 does well: A three way bookshelf speaker with KEF’s coaxial driver for stable imaging across seats and very low distortion, easy to run with a modest amp. The tradeoff: The low-frequency alignment rolls gradually rather than delivering high-output sub-bass; KEF specifies 58Hz +/-3dB and Erin’s high-level data supports using an 80Hz subwoofer crossover.
The Epos ES14N is the deeper-bass choice. A modern revival of a classic British bookshelf speaker with a time aligned sloping baffle, smooth accurate sound, and very low distortion. Its bass reaches about 51.2Hz before falling 3dB, against 58Hz for the KEF R3. The tradeoff: Off axis sound tracks the on axis response less consistently than most measured speakers as frequency rises, so the room’s reflected sound differs more from what you hear directly.
Buy the KEF R3 or the Epos ES14N on features: they are rated the same for sound quality at close to the same price.
