Short answer: the Kali Audio SM-5 for better sound quality, the JBL 305P MKII for the lower price. The Kali Audio SM-5 ranks #4 of 42 powered bookshelf speakers at $3400. The JBL 305P MKII ranks #9 at $319, $3081 cheaper.
What the Kali Audio SM-5 gets right: True coaxial design with the tweeter mounted inside the midrange. The catch: 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.
What the JBL 305P MKII offers: A fantastic value in studio monitors. Watch for: Possible slight hissing from the amps at low levels.
Buy the Kali Audio SM-5 if sound quality matters more than the price. Buy the JBL 305P MKII if the price matters more than sound quality.

Kali Audio SM-5: $3400 Sweetwater
Pros: 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.
Cons: 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.

JBL 305P MKII: $319.00 Amazon
Pros: A fantastic value in studio monitors. Extremely close to the Focal Alpha 50 EVO, almost indistinguishable. Surprisingly deep and wide soundstage. Good horizontal dispersion (~70 degrees). Has a proper limiter that controls output cleanly rather than crudely cutting bass, and holds up well under sustained loud playback with minimal thermal compression.
Cons: Possible slight hissing from the amps at low levels. Rear ported, can be an issue close to walls. A port resonance around 1.6kHz is audible and distracting on some tracks. Midrange is somewhat scooped rather than flat for a studio monitor, and treble runs about 1.5dB hot - Erin’s Audio Corner recommends using the -2dB treble shelf switch. Vertical dispersion narrows around the crossover, so try to stay within about 10 degrees of the tweeter axis.
