Definitive Technology Demand D11 vs Infinity Reference R162

Last updated: August 18, 2026

Short answer: the Definitive Technology Demand D11 for better sound quality, the Infinity Reference R162 for the lower price. The Definitive Technology Demand D11 ranks #44 of 100 bookshelf speakers at $999. The Infinity Reference R162 ranks #51 at $500, $499 cheaper.

The case for the Definitive Technology Demand D11: CEA2034 spinorama shows a mostly flat, well-controlled response - close to class-leading if not for one narrow resonance. The tradeoff: A narrow but real ~600Hz jaggy shows up consistently in on-axis and off-axis measurements.

On the Infinity Reference R162 side: CEA2034 spinorama shows good directivity with wide, consistent horizontal and vertical response, and blended early reflections that need little room treatment. Set against that: Elevated output above 3kHz adds brightness, with a resonance around 700Hz and some distortion near the crossover point.

Buy the Definitive Technology Demand D11 if sound quality matters more than the price. Buy the Infinity Reference R162 if the price matters more than sound quality.

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.

Infinity Reference R162 ranking card

Pros: CEA2034 spinorama shows good directivity with wide, consistent horizontal and vertical response, and blended early reflections that need little room treatment. 1” CMMD waveguide tweeter and 6.5” CMMD woofer, 85.5dB sensitivity.

Cons: Elevated output above 3kHz adds brightness, with a resonance around 700Hz and some distortion near the crossover point. EQ or a simple inline tweeter resistor can tame the treble; the reviewer still called it a very enjoyable system for the price. Discontinued.
