Short answer: the JBL HDI-1600 for measured smoothness, the Emotiva Airmotiv XB2 on value. The HDI-1600’s CEA2034 spinorama is very flat through the critical mid and upper frequencies with a slight bass boost and very smooth early-window directivity, its only flaw a dip above 10kHz on-axis. The XB2 is very neutral and linear at its toe-out angle and beats the similarly-priced ELAC Debut 3.0 DB63 on directivity, with a slight 2kHz upper-midrange recess.
Buy the Emotiva Airmotiv XB2, since the JBL HDI-1600 is discontinued and only worth hunting down used.

Emotiva Airmotiv XB2: $549 per pair Emotiva eBay
Older models: the Emotiva B1+ (rated 4.1/5) and the Emotiva Airmotiv B2+ (ranked lower, rated 3/5).
Pros: Very neutral, linear frequency response at the recommended toe-out angle, with better directivity than the similarly-priced ELAC DB63. Decent bass extension for a bookshelf (F3 at 62Hz). AMT folded-ribbon tweeter with a rotating waveguide for placement flexibility. Great value: rated a top-three performer for the money by Erin’s Audio Corner. Measured bass extension of 62Hz (-3dB).
Cons: Slight recessed upper-midrange around 2kHz from the tweeter-to-woofer handoff. Sounds noticeably bright pointed directly at the listener: needs toeing out 10-20 degrees, crossfiring behind the head, for the most linear result. Elevated multi-tone distortion at higher output leads to some grainy, compressed mids when pushed. Irregular compression deviations affect dynamics at higher volume. Needs a subwoofer for real bass authority.

JBL HDI-1600: $1980 per pair Discontinued Crutchfield eBay
Pros: CEA2034 spinorama is very flat in the critical mid-to-upper frequencies, with a slight bass boost that should have a good subjective effect and very smooth early-window directivity. Predicted in-room response in a simulated average listening room closely tracks the reviewer’s own preferred target curve. Measured bass extension of 55.7Hz (-3dB), with a measured sensitivity of 85dB.
Cons: A dip appears above 10kHz on-axis. Cumulative spectral decay (waterfall) shows some messiness around the crossover along with a 700Hz resonance. Harmonic distortion rises to nearly 2% right at the 1.9kHz crossover point at 96dB SPL/1m. Discontinued.
