#12 KEF Reference 203: $5000 per pair Discontinued eBay

Newer model: the KEF Reference 3 Meta, ranked lower, rated 4.6/5.

Pros: An unusually accomplished 4-way design for its era: excellent on-axis linearity (within about +/-3dB), genuinely good directivity both horizontally (~55 degrees) and vertically (~40-50 degrees), and an estimated in-room response that closely matches what the reviewer actually heard. Distortion is excellent - under 1% harmonic above 80Hz at both 86dB and 96dB, and multitone stays around 1% even at 96dB. Bass reaches a real F3 of 51Hz (F10 37Hz), with in-room extension into the low-mid-40s. The reviewer’s overall listening notes were essentially “nothing stood out bad or good” - a genuinely neutral, accurate speaker with a distinctive rounded-baffle look that avoids the diffraction issues a flat baffle this wide would normally have. Measured bass extension of 51Hz (-3dB), with a measured sensitivity of 88dB.

Cons: This is a 20+ year old, long-discontinued speaker only findable secondhand (Facebook Marketplace, Craigslist, audio forums) - condition, driver matching, and component aging vary by unit, so audition before buying if at all possible. Demands a robust amplifier: impedance dips to about 3.6 ohms with an EPDR of 2.2 ohms. The small supertweeter shows minor breakup artifacts at the extremes of the vertical polar plot and some compression at very high output in the top octave, though neither was audible in normal listening.

How it compares: Just above it: JBL 4367 - $11500 more, 4.5Hz higher bass extension (-3dB). Just below it: KEF Reference 3 Meta - $11000 more, 2Hz lower bass extension (-3dB).
