Short answer: the Philharmonic Ceramic Mini. It ranks #2 of 179 bookshelf speakers by sound quality, rated 4.7/5, at $900; the KEF LS50 Meta ranks #4, rated 4.5/5, and costs $1,199, which makes this an easy call rather than a real tradeoff.
Why pick the KEF LS50 Meta: An iconic compact KEF speaker with highly accurate sound, pinpoint imaging and a coaxial driver that keeps tone even across the room. Watch for: F3 of 67Hz and F10 of 42Hz mean it doesn’t get much below 50Hz in-room; a subwoofer is recommended for real bass.
The Philharmonic Ceramic Mini is the deeper-bass pick. A beautifully finished bookshelf speaker with near reference accuracy, low distortion, a touch of warmth and a wide soundstage. Its bass reaches about 51Hz before falling 3dB, against 68Hz for the KEF LS50 Meta. The tradeoff: Somewhat limited output capability for its size: audible woofer compression (“flopping”) around 95dB at 3 meters for a stereo pair, so keep to moderate levels or pair with a subwoofer for home theater use.
Buy the Philharmonic Ceramic Mini. It is rated higher for sound quality than the KEF LS50 Meta and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
