Short answer: the KEF R3 Meta if sound quality matters most, the Emotiva Airmotiv XB2 if price matters most. The KEF R3 Meta ranks #10 of 222 bookshelf speakers, rated 4.6/5, at $2,499.99. The Emotiva Airmotiv XB2 ranks #48, rated 4.2/5, at $549, $1,950.99 cheaper.
The KEF R3 Meta is the better-sounding 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. 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.
The Emotiva Airmotiv XB2 is the deeper-bass pick. A great value bookshelf speaker with neutral sound, an AMT ribbon tweeter, and decent bass for its size. Its bass reaches about 62Hz before falling 3dB, against 76Hz for the KEF R3 Meta. The catch: Slight recessed upper-midrange around 2kHz from the tweeter-to-woofer handoff.
Buy the KEF R3 Meta if sound quality is the priority over the price, or the Emotiva Airmotiv XB2 if the price is the priority over sound quality.
