Short answer: the Reflector Audio Square Two for better sound quality, the KEF LSX II LT for the lower price. The Reflector Audio Square Two ranks #26 of 64 powered bookshelf speakers at $6499. The KEF LSX II LT ranks #27 at $469.99, $6029.01 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 Reflector Audio Square Two offers: An exceptionally flat on-axis deviation of just 0.10dB from a coaxial horn design (four 5” woofers around a compression-driver tweeter) giving nominal 60x60 degree directivity from a compact 32cm cube, with a well-damped bass-alignment Q of 1.31. Sound on Sound’s review praised its detailed, neutral sound that stays phase-coherent with no appreciable latency. Watch for: A directivity-index standard deviation of 4.90, well above the 3-4 range typical of most monitors this size, reflects the narrow, symmetric horn pattern that Sound on Sound and ASR forum members flagged as double-edged, helpful in some rooms but limiting the sweet spot in others. Predicted in-room smoothness (0.49) is only middling, not matching the excellent on-axis figure. It’s a low-volume Latvian product with no published warranty term found anywhere.
