Short answer: the JBL 305P MKII. It ranks #17 of 100 powered bookshelf speakers by sound quality, rated 4.3/5, at $289; the Palmer STUDIMON 5 ranks #66, rated 3.6/5, and costs $350, which makes this an easy call rather than a real tradeoff.
The JBL 305P MKII is the more accurate choice. Erin’s Klippel data gives 5.38 standalone and 7.52 with an ideal subwoofer, with bass reaching -3dB around 51Hz. Its measured preference score, a predictor of how neutral it sounds, is 5.38 against 3.48 for the Palmer STUDIMON 5. Watch for: The 3.3dB midrange span and rising response show it is not perfectly neutral.
What the Palmer STUDIMON 5 does well: The available third-party measurements predict 3.48 standalone and 6.37 with an ideal subwoofer. The tradeoff: The trace spans 4.0dB from 300Hz to 5kHz and estimates -3dB bass around 80Hz, with local irregularities despite the level overall trend.
Buy the JBL 305P MKII. It is rated higher for sound quality than the Palmer STUDIMON 5 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Speakers In Full
JBL 305P MKII: $289.00 per pair Amazon eBay
Older model: the JBL LSR305 (ranked lower, rated 4.2/5).
Same family: the JBL 306P MKII (larger bookshelf, rated 4.1/5) and the JBL 308P MKII (larger bookshelf, rated 4.4/5).
Pros: Erin’s Klippel data gives 5.38 standalone and 7.52 with an ideal subwoofer, with bass reaching -3dB around 51Hz. Broad horizontal coverage and reasonably smooth reflected sound support stable imaging across a desk. The existing review reports effective limiting and little sustained thermal compression, making it a strong budget-monitor option rather than just a speaker with a promising frequency curve. Measured bass extension of 50Hz (-3dB), with a measured sensitivity of 91.1dB.
Cons: The 3.3dB midrange span and rising response show it is not perfectly neutral. A port-related feature around 1.6kHz and some excess treble can be audible; the review recommends the treble-trim switch. Vertical crossover interference makes ear height important. Amplifier hiss may matter in very quiet nearfield use, and rear-port placement needs room-boundary adjustment.

Palmer STUDIMON 5: $350 per pair Thomann eBay
Pros: The available third-party measurements predict 3.48 standalone and 6.37 with an ideal subwoofer. Balanced inputs and a conventional compact monitor cabinet make it straightforward to use with studio equipment. The broad response trend is approximately level rather than strongly bright or dark.
Cons: The trace spans 4.0dB from 300Hz to 5kHz and estimates -3dB bass around 80Hz, with local irregularities despite the level overall trend. There are no room-EQ controls to address broad placement errors, and the available score does not establish clean output.
