Short answer: the KEF LS50 Wireless II if sound quality matters most, the Edifier R1280T if price matters most. The KEF LS50 Wireless II ranks #18 of 100 powered bookshelf speakers, rated 4.3/5, at $2,999. The Edifier R1280T ranks #89, rated 3.1/5, at $119.99, $2,879.01 cheaper.
Why pick the Edifier R1280T: ASR’s review found useful moderate-level bass output from an inexpensive powered pair. The catch: Preference scores of 2.41 standalone and 5.02 with an ideal subwoofer reflect substantial tonal limitations, not just missing bass.
The KEF LS50 Wireless II is the more accurate, deeper-bass choice. Erin’s measurements give preference scores of 5.43 standalone and 7.51 with an ideal subwoofer, with a -3dB point around 51Hz. Its measured preference score, a predictor of how neutral it sounds, is 5.43 against 2.41 for the Edifier R1280T. Its bass reaches about 51.3Hz before falling 3dB, against 63Hz for the Edifier R1280T. It keeps a wired aux input, which the Edifier R1280T lacks. The catch: The 3.0dB response span is good but not reference-leading, and dispersion still varies with frequency.

Edifier R1280T: $119.99 per pair Amazon eBay
Pros: ASR’s review found useful moderate-level bass output from an inexpensive powered pair. Remote volume and bass/treble controls make it easy to use without separate amplification. Measured bass reaches -3dB around 63Hz. Measured bass extension of 63Hz (-3dB).
Cons: Preference scores of 2.41 standalone and 5.02 with an ideal subwoofer reflect substantial tonal limitations, not just missing bass. The response spans 5.5dB from 300Hz to 5kHz, and listening-window narrow-band deviation is 0.650. Resonances and treble unevenness affect reflected sound too. Listening height is important, and high-level compression changes the balance.

KEF LS50 Wireless II: $2,999.00 per pair Amazon KEF Crutchfield eBay
Same family: the KEF LSX II LT (smaller bookshelf, ranked lower, rated 4/5), the KEF LSX II (smaller bookshelf, estimated 4.1/5) and the KEF LS60 (floorstanding, rated 4.8/5).
Pros: Erin’s measurements give preference scores of 5.43 standalone and 7.51 with an ideal subwoofer, with a -3dB point around 51Hz. The coincident Uni-Q layout helps preserve tonal consistency across horizontal and vertical listening positions. Low listening-window narrow-band deviation of 0.308 supports relatively clean midrange reproduction. HDMI eARC and streaming functions make it a capable all-in-one stereo system. Measured bass extension of 51.3Hz (-3dB).
Cons: The 3.0dB response span is good but not reference-leading, and dispersion still varies with frequency. Compact bass drivers limit deep-bass output. App placement adjustments are not the same as microphone-based automatic room correction. The price and primary/secondary architecture are practical trade-offs; neither driver geometry nor a single directivity statistic guarantees the best sound in every room.
