Short answer: the KEF LS50 Meta for better sound quality, the NHT SuperZero 2.1 for the lower price. The KEF LS50 Meta ranks #4 of 179 bookshelf speakers, rated 4.5/5, at $1,599.99. The NHT SuperZero 2.1 ranks #86, rated 3.3/5, at $124.99, $1,475 cheaper.
The KEF LS50 Meta is the more accurate, deeper-bass choice. An iconic compact KEF speaker with highly accurate sound, pinpoint imaging and a coaxial driver that keeps tone even across the room. Its measured preference score, a predictor of how neutral it sounds, is 5.74 against 3.03 for the NHT SuperZero 2.1. Its bass reaches about 68Hz before falling 3dB, against 101.1Hz for the NHT SuperZero 2.1. 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.
Why pick the NHT SuperZero 2.1: Tiny, affordable sealed satellites that are easy to place near a wall, built to pair with a subwoofer. The catch: This is intentionally a satellite: estimated in-room extension is only 84Hz and the standalone preference score falls to 3.03.
Buy the KEF LS50 Meta if sound quality is the priority over the price, or the NHT SuperZero 2.1 if the price is the priority over sound quality.
