Short answer: the Emotiva Airmotiv 6s for bass and output; the JBL 306P MKII for even on-axis response. The Emotiva has lots of bass energy below 300Hz and plays louder than a JBL 305P MKII, but its listening window has a 300-600Hz suckout followed by a peak from 600Hz up. The JBL is smooth on-axis for a compact 6.5-inch monitor, with a dip around 1.6kHz.
On the JBL 306P MKII side: CEA2034 spinorama shows a nice, smooth on-axis response with very good directivity control for a compact 6.5” monitor. Set against that: A narrow but noticeable dip around 1.6kHz shows up in the on-axis and listening-window curves.
Buy the JBL 306P MKII. It is rated higher for sound quality, and the Emotiva Airmotiv 6s is discontinued, so it is only available used.

JBL 306P MKII: $398 per pair B&H Photo Video eBay
Pros: A 6.94 ideal-subwoofer score and 46.9Hz measured -3dB extension make this a useful affordable nearfield monitor. The waveguide supports broad horizontal listening coverage, and basic boundary controls help with setup. Measured bass extension of 46.9Hz (-3dB).
Cons: The 3.4dB response span from 300Hz to 5kHz is less even than the 308P MKII’s, with midrange resonances affecting neutrality. Hiss can matter at a quiet desk, while bass distortion limits demanding playback. A subwoofer improves bandwidth but does not remove the midrange irregularities. A narrow dip around 1.6kHz shows in the on-axis and listening-window curves.

Emotiva Airmotiv 6s: $800 per pair Discontinued eBay
Pros: ASR measured 49.1Hz -3dB bass extension and a 5.75 ideal-subwoofer score. The review found useful output capability, making it a credible option for ordinary nearfield playback with additional bass support when needed. Measured bass extension of 49.1Hz (-3dB).
Cons: The 3.0dB response span from 300Hz to 5kHz includes lower-midrange unevenness that can change vocal weight. Treble peaks also prevent a fully neutral balance. Equalization may help, but the substantially higher EQ-optimized score is not its native performance. A suckout between 300 and 600Hz in the listening window is followed by a peak from 600Hz up. Discontinued.
