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 congura-

tion. The titanium dome and surround are formed as one common unit.

The chamber behind the tweeter dome is resistively damped via a lled tube to

reduce reection 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 oers numerous benets, including the elimina-

tion 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 amplier. Additionally, this technique

produces smoother amplitude response through the high frequency range. With its unique horn and phase plug,

the tweeter demands far less drive current from the ampli-

er, so the driver can maintain full dynamic capability at any

volume level.

This driver is inherently at 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.

Crossover Network

Through very accurate driver engineering, the system oers excellent perfor-

mance without the need for corrections in the crossover network. A cross-

over should provide a smooth transition from driver to driver, allowing each

element to operate at its optimum performance within its designed frequency

range. This accomplished, the network can be a straightforward design and

use extremely high quality parts without imposing unnecessary budget con-

straints. A simple, elegant crossover also means the speaker will have a more

direct and coherent character as compared with products that must employ

complex networks to iron out their shortcomings. Polyester capacitors along

with all air-core inductors, ensure

best performance and longev-

ity. The network produces

a fourth-order electro-acoustic lter when combined with the

smooth, natural roll o of the drivers.

Cabinet

Functionally, any loudspeaker enclosure provides a mechanical placement

of each transducer, a method for suppressing acoustical radiations and a reso-

nant chamber to extend low frequency performance. The Palladium Series is

an artistic blend of beauty and functional performance. Its industrial design

was guided by the global consultancy of BMW Group DesignworksUSA.

Enclosure resonances can be suppressed through the geometry of the enclo-

sure and mass of the panels. The Palladium Series enclosures contain nonpar-

allel wall structures and thick, high mass walls. Nonparallel wall structures sig-

nicantly decrease standing waves. Cabinet wall

thicknesses are a minimum of 1-inch thick with

an even thicker front bae. Custom inner and

outer laminated panels sandwich a middle layer of dissimilar material designed with a

dierent mechanical impedance to ensure the cabinet does not color the sound.

To further increase enclosure stiness, “H” braces are strategically positioned in the

enclosure to reinforce the structure, control resonance and minimize modal stand-

ing waves. The massive front bae design allows all woofers and the mid/high horn

structure to mount ush to the exterior edge. The width of the front bae has also

been minimized to decrease the total area. A smaller front bae directly correlates

to improved o-axis performance. The overall enclosure was designed to extend the

low frequency response of the woofers. This fourth-order, vented enclosure contains

tuned ports cleverly blended into the rear of the enclosure. Just below the ports on

the P-38F and P-37F , a high mass aluminum and steel base is integrated into the

bottom of the enclosure. The base contains four adjustable oor anchors, which

decouple the cabinet from the oor by supporting the cabinet at just four points.

Tractrix® Horn Design

Horn-loaded technology is the driving force behind the remark-

ably accurate Klipsch sound. Horns oer high eciency, low

distortion, controlled directivity and at frequency response,

allowing them to more closely reproduce the quality and tonal

characteristics of live sound. In the Palladium Series, the high and

mid-frequency drivers both use the latest evolution of our Tractrix®

Horn design, featuring a 90° x 60° coverage pattern and a lofted

throat design for exemplary on-axis response. These horns have

been molded as a single unit, using a proprietary, acoustically in-

ert, carbon-infused thermoset composite material. The high- and

mid-frequency drivers are connected to the horns via chamber-

dampened phase plugs that result in a 4:1 compression ratio,

delivering remarkable eciency with astonishingly low distortion.

This arrangement allows the Palladium Series to provide a unique

combination of precision, clarity and eortless power.
