The case for the Polk Signature Elite ES20: Large, efficient bookshelf speakers with unusually deep bass for the price and wide horizontal coverage. Watch for: Predicted in-room smoothness of 0.238 and directivity-index consistency of 3.81 are average rather than class-leading.

Its measured preference score, a predictor of how neutral it sounds, is 6.48 against 4.49 for the Polk Signature Elite ES20. The catch: At roughly $10000/pair, nearly four times the cost of the similarly-sized KEF R3.
