Short answer: the Kali Audio SM-5 for better sound quality, the JBL One Series 104 for the lower price. The Kali Audio SM-5 ranks #4 of 64 powered bookshelf speakers at $3000. The JBL One Series 104 ranks #62 at $129, $2871 cheaper.
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.
What the JBL One Series 104 offers: Heavy internal EQ from the amplifier meaningfully compensates for otherwise poor raw driver measurements, and casual listening on undemanding content sounded like a scaled-down JBL 305P Mark II - well above typical computer-speaker quality for the price. Solid build quality for a $90-130 powered pair with dual built-in amplifiers. Watch for: Measuring the passive drivers alone (bypassing the amplifier’s EQ) showed “no bass, no low mids, and highly irregular highs” - a disaster by the reviewer’s description. Even with the amplifier’s correction applied, there’s an on-axis cancellation around 7.4kHz from the coaxial driver design, and JBL’s own published frequency-response graph uses a compressed 95dB vertical scale that hides real deviations the reviewer’s 50dB-scale CEA-2034 measurement reveals. Female vocals and “lisping” content became bright and annoying; the reviewer’s verdict was “can’t recommend it though if you want a true hi-fi experience.”
Buy the Kali Audio SM-5 if sound quality matters more than the price. Buy the JBL One Series 104 if the price matters more than sound quality.
If sound quality matters at all to you, skip the JBL One Series 104. It ranks near the bottom of the 64 powered bookshelf speakers, so look higher up the list instead.
