Short answer: the KEF LSX II LT for dispersion, the Topping MA4 for a novel budget design. The MA4 is Topping’s first loudspeaker, notable for skipping the DAC and DSP the company built its reputation on, but its on-axis deviation measures 0.503dB average, on the rougher side for this catalog, and listening window smoothness sits at a moderate 0.44. The LSX II LT spreads about +/-60 degrees each way, though small drivers leave it SPL-limited around 88-92dB/1m.
What the KEF LSX II LT gets right: 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. 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.
Buy the Topping MA4. It is rated higher for sound quality than the KEF LSX II LT.

KEF LSX II LT: $479.99 per pair Amazon eBay
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.

Topping MA4: €449 per pair Audiophonics eBay
Pros: The selected manufacturer-supplied Klippel data shows a 1.6dB span from 300Hz to 5kHz, bass reaching -3dB around 50Hz, and preference scores of 5.64 standalone and 7.83 with an ideal subwoofer. That is strong measured tonal performance for a compact monitor. Its analog crossover and balanced XLR connection suit an existing audio interface. Measured bass extension of 49.8Hz (-3dB).
Cons: The native listening-window response is not as smooth as the leading Genelec and Neumann measurements. No USB, Bluetooth or built-in room-correction DSP: source control and correction need external equipment. Bass extension alone does not establish clean output capability. On-axis narrow-band deviation measures 0.503dB and listening-window smoothness a moderate 0.44.
