Short answer: the Revel Concerta2 M16 on price, the JBL HDI-1600 on measurements. The Revel costs $600, $1,380 less and its CEA2034 spinorama is essentially flat from 200Hz to 10kHz with some bass boost around 100Hz, but harmonic distortion shows a peak around 80Hz and a sharp spike around 350Hz, and the woofer gets unhappy before the tweeter handoff. The JBL ranks #45 of 134 with a very flat spinorama, but dips above 10kHz on axis.
Buy the JBL HDI-1600 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the AsciLab C6B instead.

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.

Revel Concerta2 M16: $600 per pair used (about) Discontinued eBay
Pros: CEA2034 spinorama shows an on-axis response that’s essentially flat from 200Hz to 10kHz, with some bass boost around 100Hz. Predicted in-room response is very nice, with just extra bass and a bit of roll-off above 20kHz: the reviewer calls it “nice!” Distortion is well controlled through most of the range at both test levels. Measured bass extension of 60.1Hz (-3dB).
Cons: Harmonic distortion shows a notable peak around 80Hz and a sharp spike around 350Hz, plus the woofer appears to get a bit unhappy right before handing off to the tweeter. Cumulative spectral decay (waterfall) shows some lingering resonances in the 300Hz-1kHz region. The reviewer cautions not to over-cover the cabinet/grille area with thin fabric, as it can audibly affect the top-end response. Discontinued.
