Short answer: the Revel Concerta2 M16, narrowly. Its CEA2034 spinorama is essentially flat on-axis from 200Hz to 10kHz with some bass boost around 100Hz, though harmonic distortion peaks around 80Hz and spikes around 350Hz. The Definitive Technology Demand D11 is close to class-leading apart from one narrow resonance, a real jaggy around 600Hz that appears consistently on- and off-axis.
Buy the Revel Concerta2 M16 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.

The Two Speakers In Full
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.

Definitive Technology Demand D11: $999 per pair Discontinued Amazon eBay
Pros: CEA2034 spinorama shows a mostly flat, well-controlled response: close to class-leading if not for one narrow resonance. Distortion is well controlled and the deep cabinet lets it play loud without bottoming out except on the deepest bass content. Cabinet construction and finish are a clear step above budget speakers. Measured bass extension of 60.1Hz (-3dB), with a measured sensitivity of 87dB.
Cons: A narrow but real ~600Hz jaggy shows up consistently in on-axis and off-axis measurements. Horizontal directivity is uneven because of the offset tweeter position, giving the left and right channels slightly different off-axis energy. There’s a low-frequency rattle/noise at very deep bass levels the reviewer called “horrendous.” Discontinued; the Demand series has moved on to newer models.
