Klipsch RF-52 are 2-way floorstanding speakers in the lower half of the Klipsch Reference Series. They feature a 1" titanium tweeter for high frequencies situated behind, what Klipsch calls, a Tractrix horn and dual 5.25" mid/bass driver made of a composite ceramic and copper material that Klipsch calls Cerametallic. The 2-way crossover is set at 1900 Hz, and the speaker has reported frequency response of 34Hz to 23kHz (+/-3dB). They feature a rear-firing port to eliminate vibration and use magnetically attached grilles. The RF-52 speakers are sold individual for around $300 each or ($600 / pair) and are only available in a black woograin vinyl finish. They were first produced in 2006. The next model up is the Klipsch RF-62 ($400 / each) and the step-down model is the Klipsch RF-10 ($250 / each) with similar design, but with 6.5" and 4.5" mid-range drivers, respectively.
