Short answer: the JBL 708P for directivity, the Adam Audio T7V for nearfield neutrality. The 708P’s spinorama is extremely good both on and off axis with excellent horizontal directivity, though a port resonance creates a mild rise around 600-900Hz. 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 its narrow vertical dispersion demands sitting at tweeter height.
Buy the JBL 708P when sound quality outweighs the price for you, and the Adam Audio T7V when the price outweighs sound quality instead.

JBL 708P: $4000 per pair B&H Photo Video eBay
Pros: Erin’s measurements give 43.9Hz -3dB extension and a 6.91 ideal-subwoofer score, with useful bass from a professional active monitor. The waveguide and onboard processing make it a practical choice for a carefully installed studio system. Measured bass extension of 43.9Hz (-3dB).
Cons: The 2.6dB response span from 300Hz to 5kHz includes audible-relevance irregularities, with port-region features and vertical crossover sensitivity. High-level distortion remains a constraint. Its professional positioning and amplifier power do not make it automatically more neutral than the cheaper 308P MKII. A port resonance adds a mild rise around 600 to 900Hz, and vertical dispersion is narrower than horizontal, so stay within a few degrees of the tweeter axis.

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.
