Heresy, LA Scala, Unpacking & Assembly

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
