Short answer: the Genelec 8320A for better sound quality, the KEF LSX II LT for the lower price. The Genelec 8320A ranks #9 of 58 powered bookshelf speakers at $850. The KEF LSX II LT ranks #27 at $600, $250 cheaper.
What the KEF LSX II LT offers: Coaxial (Uni-Q-style) driver keeps the tweeter centered in the midrange, giving wide and consistent dispersion both horizontally and vertically (about ±60° each) - a wide sweet spot for multiple seats or positions. The KEF Connect app provides genuinely useful DSP control: desk/wall boundary compensation, adjustable bass contour (standard/less/extra), treble trim, and subwoofer integration, letting you tune the sound to wherever it’s placed. Distortion at a moderate 86dB looks good for the speaker’s compact size. Tonal profile stays consistent from 0° to 30° off-axis, so side-seat listeners hear essentially the same balance as someone centered. Extensive connectivity for its size: HDMI, USB, optical, sub output, plus Wi-Fi/Bluetooth. Clearly outperformed the reviewer’s soundbars, including ones bundled with their own subwoofers, as a TV audio replacement. Watch for: Small drivers mean it’s SPL-limited: bass compression kicks in around 88-92dB/1m per speaker, and multitone distortion crosses the reviewer’s 3% threshold around 96dB - not intended for loud or large-room duty. F3 of 55Hz and F10 of 46Hz mean it loses much of its bass by around 50Hz; a subwoofer (controllable through the same app) is needed for real low end. Diffraction dips appear around 4-5kHz and again near 8kHz, likely tied to the tweeter housing or surround, giving a mild reduction in treble attack and sibilance. A possible port or enclosure resonance shows up around 800Hz in the rear-radiation measurements, though the reviewer wasn’t certain of the exact cause or whether it’s audible. No analog input on this LT variant, so a turntable can’t be connected directly - only the pricier standard LSX II model includes one.
What the Genelec 8320A offers: The Directivity Control Waveguide and die cast aluminum Minimum Diffraction Enclosure produce a listening window smoothness score of 0.53 and a low frequency alignment Q of just 0.227, the cleanest, least resonant bass rolloff of any speaker in this whole batch. It network calibrates through Genelec’s GLM software for automatic room correction, and Intelligent Signal Sensing drops standby power to under 0.5W. Watch for: On axis deviation measures 0.169dB average, decent but not class leading next to the AsciLab and Audio Smile entries in this batch. The compact 4.1 inch woofer limits low frequency extension to a measured 67.4Hz at -3dB, so a subwoofer is needed for full range use. The GLM calibration kit that unlocks its room correction features is sold separately from the speaker price, and max SPL tops out around 100dB, modest next to Genelec’s larger 8000 series monitors.
