KLIPSCH R-28F

Pre owned. In good condition, with several signs of wear, some of which are shown in the photos. Supplied with user manual and original packaging.

The Klipsch Reference R-28F is a 2-way floorstanding loudspeaker featuring a bass-reflex design, developed for music reproduction and home cinema applications. Part of the Reference series, it combines high efficiency with a construction designed to fill medium to large rooms, delivering dynamic performance even when paired with relatively low-powered amplifiers, provided they have an adequate power supply.

The high-frequency section features a 1" aluminium-dome tweeter incorporating LTS (Linear Travel Suspension) technology, designed to control diaphragm movement and reduce distortion. The driver is coupled to a Tractrix acoustic horn, which controls dispersion in both the horizontal and vertical planes, providing wide sound coverage and good intelligibility. This design also helps maintain directivity and reduce high-frequency attenuation as the listening distance increases.

The mid-bass section features two 8" woofers with IMG (Injection Molded Graphite) cones, made from graphite and finished in copper. The drivers are equipped with substantial magnets and operate within a bass-reflex enclosure featuring a flared front-firing laminar port, designed to reduce airflow noise during playback at high volume levels. The specified frequency response extends down to 35 Hz, allowing music to be enjoyed without necessarily requiring a subwoofer.

With a sensitivity rating of 98 dB, the R-28F can achieve high sound pressure levels without requiring particularly powerful amplification. Its dynamic range and controlled dispersion contribute to clear, impactful reproduction of both music and movie soundtracks.

The cabinet features a brushed black polymer finish, complemented by the copper-coloured woofers, distinctive elements of the Reference series design.
