What You Need to Know About Installing Klipschorns The Klipschorn® requires corner placement because the walls of the room serve to complete the speaker's low frequency horn. To achieve full low frequency extension, the Klipschorn® should fit tightly in a corner without baseboard or trim interference and the wall surfaces should extend at least 25 inches beyond the side grilles without obstructions. The Klipschorn is equipped with rubber wall seals to ensure airtight contact with the wall. Ideally the corners should be at least 8' but less than 20' apart with the ability to place the listener at least as far back from the plane of the speakers as they are apart. In situations where the Klipschorns will be greater than 20 feet apart a proper stereo image may not develop between your speakers. A third speaker, such as the La Scala II, can be installed in between widely spaced Klipschorns and fed a mono signal to compensate for this: The following page includes a Klipschorn tail board notch drawing. Print out, cut along the curved black line and place in contact with your floor board trim at a 45 degree angle to determine if there will be any corner fit issues. For rooms that lack appropriate corners, have only one good corner or have corners that are too far apart, false corners can be constructed that will provide 90% of the performance of a proper corner: Please contact Klipsch Technical Support at (800) 554-7724 for more detail. ...
