“In the

a frivolous activity”

“In the real world, one wishes to know more than we presently know about measurements and their relation to perceptions”

To achieve the target, prudent design decisions must be made.

Optimum performance is achieved by identifying the correct priorities

Tradeoffs are always involved in engineering, speaker engineering is not exempt

Revel was founded to create the world’s finest speakers, and endowed with resources to accomplish it.

Revel is grounded in innovative and compelling research.

Research has established a correlation between

what we hear and what we measure.

Revel tests their product using double blind listening trials. The net result is a speaker that is superior by choice.
