Short answer: the KEF Q Concerto Meta on measured sound quality, the Emotiva Airmotiv XB2 on price. The KEF Q Concerto Meta ranks #11 of 222 bookshelf speakers, rated 4.6/5, at $1,399.99. The Emotiva Airmotiv XB2 ranks #48, rated 4.2/5, at $549, $850.99 cheaper.
The KEF Q Concerto Meta is the better-sounding, deeper-bass choice. A neutral three way bookshelf speaker that sounds consistent from seat to seat, with smooth treble that many rivals at its price lack. Its bass reaches about 53Hz before falling 3dB, against 62Hz for the Emotiva Airmotiv XB2. The catch: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
What the Emotiva Airmotiv XB2 does well: A great value bookshelf speaker with neutral sound, an AMT ribbon tweeter, and decent bass for its size. The tradeoff: Slight recessed upper-midrange around 2kHz from the tweeter-to-woofer handoff.
Buy the KEF Q Concerto Meta if sound quality is the priority over the price, or the Emotiva Airmotiv XB2 if the price is the priority over sound quality.
