Short answer: the Reflector Audio Square Two on measured sound quality, the KEF LSX II LT on price. The Reflector Audio Square Two ranks #5 of 100 powered bookshelf speakers, rated 4.5/5, at $6,499. The KEF LSX II LT ranks #35, rated 4.0/5, at $699.99, $5,799.01 cheaper.
What the KEF LSX II LT does well: The coincident driver provides useful consistency across listening positions, and the app offers placement and subwoofer adjustments. The tradeoff: The 3.4dB midrange response span and treble-region dips keep it below more neutral monitors.
The Reflector Audio Square Two is the more accurate option. The manufacturer-supplied data shows a very small 1.1dB span from 300Hz to 5kHz and preference scores of 6.52 standalone and 8.34 with an ideal subwoofer. Its measured preference score, a predictor of how neutral it sounds, is 6.52 against 4.81 for the KEF LSX II LT. The tradeoff: The nominal 60-by-60-degree pattern calls for careful aiming and gives less freedom to move than wide-dispersion monitors.
Buy the KEF LSX II LT if the price matters more than sound quality. Buy the Reflector Audio Square Two if sound quality matters more than the price.

The Two Speakers In Full
KEF LSX II LT: $699.99 per pair Amazon eBay
Same family: the KEF LSX II (larger bookshelf, estimated 4.1/5), the KEF LS50 Wireless II (larger bookshelf, ranked higher, rated 4.3/5) and the KEF LS60 (floorstanding, rated 4.8/5).
Pros: The coincident driver provides useful consistency across listening positions, and the app offers placement and subwoofer adjustments. Erin’s measurements give preference scores of 4.81 standalone and 7.03 with an ideal subwoofer, with -3dB bass around 56Hz. HDMI and USB connectivity make it convenient for a small TV or desktop system. Horizontal and vertical dispersion both reach about ±60°, giving a broad sweet spot for more than one seat. Measured bass extension of 55Hz (-3dB), with a measured sensitivity of 84dB.
Cons: The 3.4dB midrange response span and treble-region dips keep it below more neutral monitors. The existing review finds bass compression around 88-92dB/1m and rising distortion at higher levels, so the small drivers suit close listening rather than a large room. This LT version has no analog input; a turntable cannot plug straight into it.

Reflector Audio Square Two: $6,499 per pair Monheim Microphones eBay
Pros: The manufacturer-supplied data shows a very small 1.1dB span from 300Hz to 5kHz and preference scores of 6.52 standalone and 8.34 with an ideal subwoofer. Its horn-centered layout and four surrounding woofers offer a compact, controlled-radiation monitor, with a measured -3dB point around 49Hz. The linked Sound on Sound review also supports its use for detailed monitoring.
Cons: The nominal 60-by-60-degree pattern calls for careful aiming and gives less freedom to move than wide-dispersion monitors.
