Short answer: the JBL 308P MKII for a flatter on-axis response; the Adam Audio T7V for nearfield balance. The T7V is quite balanced and neutral, very close to the Yamaha HS8, but its on-axis response is a bit wide for a nearfield and narrow vertical dispersion means sitting at tweeter height. The JBL is essentially flat from 45Hz to above 15kHz with almost no directivity error and a resonance around 18kHz.
Buy the JBL 308P MKII. It is rated higher for sound quality than the Adam Audio T7V and costs less, which makes it the one to get unless you need something the other one does better.

JBL 308P MKII: $298 per pair Amazon B&H Photo Video eBay
Pros: A 1.8dB response span from 300Hz to 5kHz and 7.69 ideal-subwoofer score support unusually good tonal balance for an accessible studio monitor. Measured -3dB extension of 42.5Hz supplies useful musical bass, and the waveguide helps maintain consistent horizontal coverage. Measured bass extension of 42.5Hz (-3dB).
Cons: Amplifier hiss may be noticeable in quiet, close-range use. Bass distortion and output limits matter when playing loudly, despite the 8-inch woofer. Keep the tweeter near ear height; vertical crossover behavior is less forgiving than the best coaxial designs. A resonance around 18kHz and a slight dip around 1.4kHz.

Adam Audio T7V: $579.98 per pair Amazon eBay
Pros: Audioholics’ measurements provide useful evidence about the midrange and treble, with a digitized 2.4dB response span from 300Hz to 5kHz. Basic tonal controls and analog connections suit a straightforward nearfield system. Measured bass extension of 65Hz (-3dB).
Cons: Correct listening height is important for the two-way crossover. Basic shelf controls offer less adjustment flexibility than parametric room correction.
