#10 KEF R5: $2,999 per pair Discontinued eBay

Pros: Slim three-way tower with the acoustic advantages of KEF’s coincident Uni-Q midrange/tweeter: horizontal and vertical off-axis responses track the direct sound smoothly, producing stable imaging and a well-behaved directivity index. Erin measured deep low-frequency reach for the cabinet width (77Hz F3 but 33Hz F10) and less than 1% harmonic distortion at 86dB. At 96dB it remains clean when high-passed, and its mild response deviations are suitable for equalization because the radiation pattern stays orderly. Measured bass extension of 77Hz (-3dB), with a measured sensitivity of 86dB.

Cons: The unusual gap between 77Hz F3 and 33Hz F10 indicates a gradual bass contour rather than flat deep-bass output; a subwoofer and roughly 80Hz high-pass are recommended for high-level playback. Erin measured a minimum near 3.5 ohms around 150Hz, although most of the curve remains above 4 ohms, so amplifier quality still matters. Sensitivity is approximately 86dB/2.83V/1m. At 102dB, compression reaches roughly 1dB around 150Hz, showing the limits of the twin 5.25-inch woofers. This original model lacks the Meta version’s MAT rear-wave absorption. Discontinued.

How it compares: Just above it: KEF R5 Meta - $1001 more. Just below it: Revel F226Be - $4701 more, 3.7Hz higher bass extension (-3dB).
