KEF Reference 1

KEF Reference 1 Bookshelf Loud Speaker Features

The unique feature of the Reference 1 speaker is its bass port or bass port tubes. The loud speaker comes with two, which can be easily changed by the owner to fine-tune the speakers’ bass balance in their room. The speaker measures 17.3 × 8.1 × 16.9 inches (440 × 205 × 430 mm) and weighs a rather substantial 40.1 pounds (18.2 kilogram). The loud speaker comes with biwire connectors and the Reference 1’s impedance is rated at 8 ohms.

Unlike the conventional speakers, the KEF Reference 1 have a midrange and treble drive units mounted one above the other, the speaker has a single Uni-Q driver with an integrated 5 inch (125 mm) midrange and 1 inch (25 mm) treble unit. The Uni-Q driver gives a more coherent sound compare to the separate tweeter and midrange driver. The speakers mounted on shelves or stands, Uni-Q’s inherently wide, even dispersion also makes it the perfect rear channel speaker in a home theatre system that effortlessly reveals all the subtitles encoded in modern soundtracks. The speaker also features a 6.5 inch (165 mm) woofer.

The front baffle of the speakers was designed to minimize the frequency response anomalies caused by diffraction – the baffle is made from a specially laminated aluminum/resin composite and secured to the Reference 1’s cabinet with high tensile bolts to enhance rigidity.

KEF Reference line also offers two towers, Reference 3 and Reference 5; two center channel speakers, Reference 2c and Reference 4c; and the Reference 8b subwoofer.
