CONTENTS
This package should contain 2 sets (4 each) of feet. The rubber feet are used for solid flooring such as wood, tile and concrete, and the chrome-plated spikes are used for carpet. Spikes may be used on solid flooring when placed on chrome plated isolation discs.
UNPACKING
Place the package on the floor with the box flaps up. Cut the tape with a utility knife to open the package. Fold the carton flaps back and carefully slide the speaker and packaging from the box, or turn the box over with flaps open and remove the box. Stand the speaker and packing upright, making sure the loudspeaker plinth is on the bottom, and remove the packing material.
CONNECTING YOUR FLOORSTANDING LOUDSPEAKERS
All three floorstanding loudspeakers have the same quality nickel-plated binding posts that will accommodate stripped wire, spade connectors or banana plugs. Be sure to use quality speaker cables, up to 12 gauge (AWG). The lowest gauge possible is recommended. Before using banana plugs, be sure to remove the black and red inserts on the binding posts. The straps connecting the binding posts should remain in place for conventional wiring, but may be removed where bi-wiring is preferred. See the following diagrams in the AMPLIFICATION section for further instruction.
AMPLIFICATION
Conventional amplification involves a single stereo amplifier wired to a single set of binding posts with straps connecting the second set of posts as seen in diagram above.
Simply attach the positive wire + to the red post, and the negative wire – to the black post.
BI-AMPLIFICATION
This connection method (see diagram above) uses two separate two channel amplifiers to power one set of speakers. One stereo amplifier connects to one speaker, and the other identical amplifier powers the second speaker. This is referred to as bi-amplification.
Be sure to remove the terminal straps before using the bi-amplification method. Connect positive + and negative – cables from the amplifier to the top terminals, and make sure the connection is tight. Connect the second set of cables (positive and negative) to the bottom terminals and tighten. Repeat these same steps using the second amplifier to connect to the second terminals.
ROOM POSITION
Placement of your floorstanding loudspeakers is a personal preference, but it is recommended that speakers be placed at least 6 feet apart whether they are being used for a stereo application, or as the main left and right channels for a home theater. For best imaging and separation, listening distance from the speakers should be about 1.5 times the distance the speakers are apart from each other.
Example: If the distance between each speaker and the listening position is 9 feet, then the speakers should be 6 feet apart from one another.
Also be sure that loudspeakers are placed at least 12 inches away from any wall. Further adjustments can be made to optimize your listening experience.
NOTE: When moving floorstanding loudspeakers take extra caution to place hands in a position that will not damage the drivers. This can best be done by placing one hand in the port at the back of the loudspeaker, and the other hand at the either top corner.
SPIKE AND RUBBER FEET
LIst of items included in package:
Spiked and rubber feet are to be used for bass decoupling (reducing bass transmission) and should only be used when plinth is on the bottom of the speaker. To install metal spiked feet, first thread ridged discs onto the metal spikes until flush. Follow by threading both into the insert at the bottom corners of the plinth. To level the speaker, height may be adjusted by turning the spike ONLY.
To avoid damage to floors other than carpet, the metal spike can be used with protective ring as shown below left. Threaded rubber feet can be used on virtually all surfaces. Installation is shown below on right
PORT TUNING
If placing your floorstanding loudspeakers 6 inches or closer to a wall, bass output can be controlled by reducing the amount of air flow from rear ports. You can “tune” bass output by using the tuning stops provided with your loudspeaker by inserting as shown. NOTE: Port tuning stops included in Kendall model ONLY
