Short answer: the KEF R3 Meta. It ranks #10 of 222 bookshelf speakers by sound quality, rated 4.6/5, at $2,499.99. The Zu Audio Method ranks #220, rated 2.0/5, at $700, $1,799.99 cheaper, not enough of a saving to outweigh the sound-quality gap.
The KEF R3 Meta is the more accurate, deeper-bass pick. A three way bookshelf speaker with KEF’s coaxial driver, superb accuracy that holds across the room, and bass that reaches deep for its size. Its measured preference score, a predictor of how neutral it sounds, is 6.10 against 0.25 for the Zu Audio Method. Its bass reaches about 76Hz before falling 3dB, against 92Hz for the Zu Audio Method. Watch for: Pointed straight on-axis, there’s a 1-2dB bump around 9kHz that stays consistent across angles thanks to the constant-directivity waveguide: only toeing the speaker out about 10° tames it.
What the Zu Audio Method does well: A very easy to drive bookshelf speaker with an 8 inch coaxial driver that plays loud from small amplifiers. The tradeoff: A severe suckout in the 1.5-3kHz range (down as much as 19dB below the mean at its worst) removes attack and clarity from brass, woodwinds, and snares, and gives an overall laid-back, unengaging character.
Buy the KEF R3 Meta. It is rated higher for sound quality, and saving $1,799.99 with the Zu Audio Method does not make up for the sound-quality gap.
