Short answer: the KEF Q1 Meta, if you are buying new. The KEF Q150 ranks higher than it (#48 vs #65 of 179 bookshelf speakers, 3.7/5 vs 3.6/5) but is discontinued, so only consider it used; the KEF Q1 Meta is still sold new at $399.99.
The KEF Q150 is the deeper-bass option. Compact bookshelf speakers with a tweeter set in the center of the woofer, usable ported or sealed and easy to correct with EQ. Its bass reaches about 51Hz before falling 3dB, against 65.1Hz for the KEF Q1 Meta. The catch: A high-frequency lift in the estimated in-room response makes it sound noticeably brighter in an untreated room than in a heavily acoustically-treated one: a real preference factor depending on your room’s furnishings.
The case for the KEF Q1 Meta: Compact bookshelf speakers with a coaxial driver, an absorber behind the tweeter, an even tonal balance and respectable bass for the size. Watch for: The only measurements are KEF’s own, not independently verified, and spinorama.org computes no preference score for them because the data is truncated at low frequencies.
Buy the KEF Q1 Meta, since the KEF Q150 is discontinued and only worth hunting down used.
