The Palladium P-39F is a three-way loudspeaker with a fourth-order crossover. The cones of its three 9" woofers are constructed from an outer aluminum skin bonded to a Rohacell core, this in turn bonded to Kevlar. The result is a rigid but lightweight diaphragm. Each woofer's basket is cast aluminum, and its 1.5"-diameter voice-coil is wound from flat copper-clad aluminum wire. Three different neodymium magnets make up the drive system.

The mid-frequency driver is front-loaded with a modified Tractrix horn with a 4:1 high-compression phase plug in its center. The 4.5" inverted-dome driver is a first for Klipsch—although the company does credit PWK's famous dictum "The midrange is where we live." The midrange is claimed to have a raw sensitivity of 110dB. Like the woofers, the midrange driver uses three magnets (the primary magnet uses the other two to stabilize its output). The midrange driver is housed in its own tuned, sealed enclosure within the P-39F's shell.

The tweeter is also front-loaded with a Tractrix horn, this one with a 10:1 compression phase plug and a 0.75" dome diaphragm of titanium. The space behind the driver is a resistively damped tube. Klipsch says that the design of the phase plug "extends the upper frequency of the driver by 10kHz," which is said to have the salubrious effect of eliminating standing waves in the high-pressure layer between plug and driver.

The fourth-order crossover is built on two printed circuit boards mounted to the bottom plate of the speakers with isolation grommets. The parts quality is said to be superb: air-core conductors, polypropylene caps, ultra-low-inductance resistors, etc. The woofers cross over to the mids at 500Hz, the mids cruise from 500Hz to 3.2kHz, and Klipsch claims the tweeter goes from 3.2 to 30kHz!

Are there better loudspeakers for $20,000/pair than the Klipsch Palladium P-39F? Possibly—I haven't heard every one of them yet. (Give me time and I'll certainly try.) What I can tell you is that the P-39F surprised me with its balance, lively sound, and ungimmicky naturalness. It's well built and, I think, really good-looking. If, like me, you think you know what a horn speaker sounds like, the P-39F just might astound you. It certainly astounded me. It's what you learn after you know it all that really counts.

Overall, this is impressive measured performance, suggesting that Klipsch has some excellent speaker engineers on staff.
