The Reference 203

Reference 203

The 203 shares all this technical virtuosity, only on a slightly smaller scale.

Computer matched high order 4-way crossovers assure fluid transitions between the five drivers:

The Hypertweeter, the new UNI-Q coincident source midrange/HF and the two high-tech 165mm (6 1/2”) LF drivers. With KEF's ultra low distortion motor systems and stiff, lightweight reinforced diaphragms, they deliver deliciously open bass with incredibly low distortion even at high volume.

The curved section cabinets are massively braced to eliminate box colourations, and the open chassis design with vented cones eliminates any trapped air noise. Magnetically shielded like the rest of the range, the 203 combines heavyweight muscle with intricate delicacy right across the frequency range. Stereo imaging is superb, the detailing immaculate and the response so fluid you could almost drink it.
