Short answer: the JBL 705P for measured accuracy; the 305P MKII for value. The 705P’s spinorama shows flat response with excellent directivity, similar to its larger 708P sibling, though a cancellation around 750Hz and a boost at the 1.75kHz crossover show in the on-axis curve. The 305P MKII remains a fantastic value, with possible slight amp hiss at low levels.
On the JBL 305P MKII side: A fantastic value in studio monitors. Set against that: Possible slight hissing from the amps at low levels.
Buy the JBL 305P MKII. It is rated higher for sound quality than the JBL 705P and costs less, which makes it the one to get unless you need something the other one does better.

JBL 305P MKII: $289.00 per pair Amazon eBay
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.

JBL 705P: $1998 per pair B&H Photo Video eBay
Pros: ASR’s data gives bass reaching -3dB around 48Hz and a 6.71 ideal-subwoofer preference score. Its waveguided compression driver and dedicated amplification are suited to studio use, and the broad response trend is close to level. It has useful low-frequency reach for a five-inch monitor. Measured bass extension of 47.6Hz (-3dB).
Cons: The standalone score is 4.70, and a localized cancellation near 750Hz contributes to the large 7.8dB midrange response span. A crossover-region rise also prevents reference-flat reproduction. An average flat trend does not erase these features, and amplifier wattage is not a measured clean-SPL rating. The data does not support calling it uniformly flat simply because it shares technology with larger JBL models.
