NEW IN BOX, THESE SOUND GREATBOX ISNT PERFECT

Klipsch Palladium 4.5 Midrange Replacement Speaker for the following model speakers P-39F, P-38F, P-37F, P-17B, P-27C These were removed from a pair of Pallidum P-39F Floor Standing Speakers. These are in good working order. Please see pics for cosmic condition. The pics are a combination of the 2 speakers we have in-stock at time of listing. Description from owners manual: Midrange - “The midrange is where we live.” Paul W. Klipsch The inverted dome midrange driver operates from 500 Hz to 3.5 kHz and is a unique design, not found on any previous Klipsch product. The driver sensitivity of 106 dB allows minimal excursion at normal playback volume. As cone excursion reduces, so does distortion. The 4.5-inch aluminum dome is driven by 3 high temperature N35H neodymium magnets, ensuring linearity under a range of listening volumes. The pole piece is topped by a copper cap to minimize unwanted inductive components. The surround has half the density of the material typically used and thus offers reduced mass. Unlike most designs, this midrange driver delivers much more output from the dome and less from the surround. As a surround is always in motion and always changing shape, output from its surface is high in distortion—minimizing surround surface area is another means to reducing overall distortion. The midrange unit is housed in its own magnetically-shielded sealed enclosure, which isolates the driver from acoustic energy generated by the woofers. Every effort has been made to ensure great accuracy, as well as long-term durability from this unique driver.

Klipsch Palladium High Frequency Replacement Tweeter works in the following models P-39F, P-38F, P-37F, P-17B, P-27C This was removed from a Pallidum P-39F Floor Standing Speakers. it is in good working order. Please see pics for cosmic condition. Description from owners manual: Treble Compression Driver Low distortion, high sensitivity, wide bandwidth and neutral tonality have been, in this ground-breaking design, pushed beyond the standards for any previous Klipsch driver. Built around a .75-inch titanium dome, the tweeter makes use of two very large high temperature N35H neodymium magnets in an unconventional configuration. The titanium dome and surround are formed as one common unit. The chamber behind the tweeter dome is resistively damped via a filled tube to reduce reflection of the back wave—and thereby the distortion that would otherwise be produced. The phase plug that puts the dome into a compression mode also has a unique chamber within it that extends the upper frequency limit of the driver. This proprietary technique offers numerous benefits, including the elimination of undesirable standing waves in the high pressure layer between the phase plug and horn. The result is a smooth impedance transfer function, and a benign load on the partnering amplifier. Additionally, this technique produces smoother amplitude response through the high frequency range. With its unique horn and phase plug, the P-39F tweeter demands far less drive current from the amplifier, so the driver can maintain full dynamic capability at any volume level. This driver is inherently flat from 3 KHz to 30 KHz. and has an inherent sensitivity some 10 dB greater than direct radiating designs. Distortion is also reduced by a factor of 10 dB, against conventional tweeters
