Short answer: the Kali Audio SM-5 for better sound quality, the Edifier MR4 for the lower price. The Kali Audio SM-5 ranks #4 of 64 powered bookshelf speakers at $3000. The Edifier MR4 ranks #31 at $129.97, $2870.03 cheaper.
What the Edifier MR4 offers: More balanced than the R1280DB. The value king. Impressively deep, flat bass down to 70Hz for such a small speaker, and its waveguide gives it unusually wide, consistent horizontal directivity for the price. Balanced XLR/TRS inputs are rare this cheap. Watch for: No Bluetooth unlike other Edifier models. Distortion climbs sharply above 86dB SPL, breaking into audible squealing near 96dB, and there’s a dip in the lower treble that needs a bit of EQ or the rear HF control to smooth out. Playback volume is limited with bass-heavy material - pushing it loud brings audible clicking/static.
What the Kali Audio SM-5 offers: True coaxial design with the tweeter mounted inside the midrange, and an unusually large waveguide that extends into the front baffle itself - directivity is excellent both horizontally (about +/-55 degrees) and vertically (+50/-40 degrees), so off-axis and low-seated listening positions still get a consistent tonal balance. Overall linearity is very good with in-room extension to about 40-45Hz. Distortion at 96dB is very low through the midrange, with only a mild, expected breakup around 3kHz tied to a small dip in the response there. Built-in DSP with free downloadable software lets you EQ each speaker individually for placement or room correction without an outboard processor, and the cabinet is wall-mountable - useful for surrounds, front heights, or tight desk setups. Compares very favorably to Kali’s own IN-8: similar raw linearity and distortion, but without the IN-8’s diffraction issues above 7kHz. Watch for: Bass output is limited by the 5” mid-bass driver - don’t expect much excursion or high-SPL low end, though extension itself is reasonable for the size. A mild high-Q resonance lingers around 2.5-4kHz in burst decay, though not strong. Instantaneous dynamic range is limited to roughly 96-102dB at 1m before compression sets in.
