Klipsch Heresy III Speaker User Manual


 
praised loudspeakers in the world and is the only loudspeaker
that has been in continuous production for over 60 years. The
Klipschorn is a testament to design that stands the test of
time. With extremely high sensitivity, this three-way, fully horn-
loaded loudspeaker with a folded tri-hedral bass horn utilizes
the walls and corners of the listening room as part of its
design. This combination of attributes enables it to span more
than nine full octaves with dynamic, smooth, ultra low
distortion sound.
HERESY III
First introduced in 1957, the Heresy started life as a compact
center channel speaker for the Klipschorn in three-speaker
stereo arrays. The Heresy is a compact, three-way design that
uses horn-loaded compression drivers for midrange and treble
reproduction and a direct radiating 12-inch woofer for the low
frequencies.
CORNWALL III
The Cornwall was introduced in 1959 as a larger full range
alternative to the Heresy as a center channel speaker in a
three-speaker stereo array. It provided the full range bass
response of the Klipschorn with sensitivity and output closer to
the fully horn-loaded models. Like the Heresy, the Cornwall is
a three-way design utilizing horn-loaded compression drivers
for midrange and treble frequencies and a direct radiating
15-inch woofer for the low frequencies.
LA SCALA II
The La Scala was developed as a more portable Klipschorn to
serve as a public address speaker for the 1963 gubernatorial
campaign of Winthrop Rockefeller. Like the Klipschorn, it
displays extremely high sensitivity and is a fully horn-loaded,
three-way speaker featuring a shorter, two-fold bass horn that
can operate independently of listening room corners. As a
result, the La Scala’s only sonic compromise as compared to
the Klipschorn is a slightly higher bass cutoff.
UNPACKING & ASSEMBLY
Heresy III and Cornwall III
The Heresy III and Cornwall III models are large, heavy speak-
ers. It is recommended that two people unpack and install
these models. Open the top carton flaps, invert the carton and
pull it up and off of the speaker. Remove the internal packing
and save for future use.
Klipschorn and LaScala II
The Klipschorn and La Scala II low and high frequency
cabinets are shipped in two separate cartons. Unpacking and
setup will require two people.
The Klipschorn and LaScala II high and low frequency
cabinets are matched by serial number for proper
acoustic performance. Please take care to match upper
and lower cabinet serial numbers when assembling these
loudspeakers.
Low Frequency Cabinet
: After opening the top flaps of the
low frequency carton, invert the carton and lift it off of the
speaker cabinet. Remove the inner packing and plastic
sheeting. The top of the cabinet, with its rubber bumpers,
should be facing up.(See Figures 1 and 2.)
Klipschorn
Slide the bass cabinet into the corner where it will be placed
for a test fit and make note of any obstructions that interfere
with a tight fit. Remove the cabinet from the corner to install
the high frequency cabinet. There is a left and a right low fre-
quency cabinet with respect to the input panel. This allows the
speaker’s binding posts to be oriented toward the electronics
to minimize the length of speaker wire. In preparation for
hookup, position the speaker near, but not tight into, the
corner and remove the low frequency grille (two wing nuts) on
the input panel side of the cabinet and set aside until the
connection process is complete.
Open the top flaps of the high frequency carton marked “Open
This End” and invert the carton. Lift the carton up off the
cabinet and remove the packing pad. Lift the high frequency
cabinet off the floor and set it on top of the low frequency
cabinet, aligning the three rubber bumpers on the top of the
low frequency cabinet with the three recesses on the under-
side of the high frequency cabinet. Thread the high and mid
frequency driver leads in the upper cabinet through the hole in
the cabinet’s lower panel. Connect the Green (+) tagged pair
of wires to the pair of binding posts labeled “Tweeter Out.”
Take care to match the Red (+) and Black (-) binding posts
with the Green (+) and Black (-) sleeves on the ends of these
wires. Follow this same procedure to connect the Yellow
tagged pair of wires to the pair of binding posts labeled “Mid
Out.” (See Figure 5.)
La Scala II
For the La Scala II high frequency cabinet, open the top flaps
of the high frequency carton marked “Open This End.” The
bottom of the cabinet should be facing up with the low fre-
quency connection cable attached to it. Free this cable, invert
the carton and lift it off the cabinet. With assistance, lift the
high frequency cabinet off the floor and carefully rest the rear
portion on top of the front half of the low frequency cabinet.
Secure the low frequency cable to the input connectors on the
12
