Short answer: the HEDD Type 05 A-CORE for better sound quality, the KEF LSX II LT for the lower price. The HEDD Type 05 A-CORE ranks #24 of 100 powered bookshelf speakers, rated 4.2/5, at $1,398. The KEF LSX II LT ranks #35, rated 4.0/5, at $699.99, $698.01 cheaper.
The case for the KEF LSX II LT: The coincident driver provides useful consistency across listening positions, and the app offers placement and subwoofer adjustments. Watch for: The 3.4dB midrange response span and treble-region dips keep it below more neutral monitors.
The HEDD Type 05 A-CORE is the more accurate, deeper-bass option. ASR’s Klippel data shows useful bass reach for this size, with -3dB around 44Hz. Its measured preference score, a predictor of how neutral it sounds, is 5.35 against 4.81 for the KEF LSX II LT. Its bass reaches about 43.9Hz before falling 3dB, against 55Hz for the KEF LSX II LT. It has an adjustable EQ, which the KEF LSX II LT lacks. The catch: The 2.7dB midrange span and listening-window narrow-band deviation of 0.404 trail the most linear monitors here.
Buy the KEF LSX II LT when the price outweighs sound quality for you, and the HEDD Type 05 A-CORE when sound quality outweighs the price instead.

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.

HEDD Type 05 A-CORE: $1,398 per pair B&H Photo Video eBay
Same family: the HEDD Type 07 A-Core (larger bookshelf, estimated 4.2/5).
Pros: ASR’s Klippel data shows useful bass reach for this size, with -3dB around 44Hz. Preference scores of 5.35 standalone and 7.23 with an ideal subwoofer support it as a balanced all-round option. The AMT tweeter and analog signal path appeal to users who want a studio monitor without digital conversion or firmware dependence. Measured bass extension of 43.9Hz (-3dB).
Cons: The 2.7dB midrange span and listening-window narrow-band deviation of 0.404 trail the most linear monitors here. The response rises modestly toward the treble. The analog-only design does not provide built-in room correction or digital inputs, and published amplification power should not be read as a measured clean-output rating.
