Brand: Definitive Technology
#44 Definitive Technology Demand D11: $999 Discontinued Amazon
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.
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. Discontinued.
How it compares: Just above it: Yamaha NS-800A - $3801 more, 5.1Hz lower bass extension (-3dB). Just below it: Dynaudio Contour 20i - $4751 more, 7.5Hz lower bass extension (-3dB).
