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 ¾” 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 as against conventional tweeters.
Crossover Network
The network is a two board construction located adjacent to the speaker's base
plate which also allows for the tri-wire input connectors to be conveniently
located at floor level. This minimizes the length of speaker wire and produces a
clean finished look.
Through very accurate driver engineering, the system offers excellent
performance without the need for corrections in the crossover network. A
crossover 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 constraints. 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 longevity. The network produces a 4th order electro-acoustic filter
when combined with the smooth, natural roll off of the drivers.
