Short answer: the JBL 305P MKII. It ranks #17 of 100 powered bookshelf speakers by sound quality, rated 4.3/5, at $289; the Mackie MR524 ranks #32, rated 4.0/5, and costs $379.98, so there is not much of a tradeoff to weigh.
What the JBL 305P MKII does well: Erin’s Klippel data gives 5.38 standalone and 7.52 with an ideal subwoofer, with bass reaching -3dB around 51Hz. The catch: The 3.3dB midrange span and rising response show it is not perfectly neutral.
What the Mackie MR524 does well: The available third-party data suggests a useful combination of bass reach and midrange balance: -3dB around 46Hz, a 2.0dB midrange span, and preference estimates of 5.11 standalone and 7.06 with an ideal subwoofer. The tradeoff: The measured response trends upward toward the treble by about 0.47dB per octave, which can lend a brighter balance.
Buy the JBL 305P MKII. It is rated higher for sound quality than the Mackie MR524 and costs less, which makes it the one to get unless you need something the other one does better.

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.

Mackie MR524: $379.98 per pair B&H Photo Video eBay
Same family: the Mackie MR624 (larger bookshelf, estimated 4/5) and the Mackie MR824 (larger bookshelf, estimated 4/5).
Pros: The available third-party data suggests a useful combination of bass reach and midrange balance: -3dB around 46Hz, a 2.0dB midrange span, and preference estimates of 5.11 standalone and 7.06 with an ideal subwoofer. Balanced inputs, boundary compensation and treble trim are practical studio features. Measured bass extension of 46.2Hz (-3dB).
Cons: The measured response trends upward toward the treble by about 0.47dB per octave, which can lend a brighter balance. Boundary compensation and treble trim help with setup but are less flexible than parametric correction.
