Installation and operation unpacking, handling and after care These Blade speakers are packed one speaker per carton. Prior to unpacking, please ensure that the serial numbers of the speakers supplied match each other. Then, unpack the speakers carefully following the instructions printed on the carton and inspect for any sign of damage. Your speakers left KEF in perfect condition. If any damage is apparent, you should notify your retailer or consultant immediately.
Installation and operation speaker placement and room acoustics Positioning the speaker in a corner or near to a side wall is not recommended as the significant bass boost caused by this position will affect the sound and cause the stereo image to deteriorate. It is best to place the speakers symmetrically within the room, relative to the walls, ceiling and floor, where possible.
Installation and operation amplifier to speaker connections All connections should be made with the amplifier switched OFF. Ensure the integrity of all connections prior to switching the amplifier ON. KEF Blade speakers are fitted with purpose designed silver-plated Bi-wire/Bi-amp terminals which will accept bare wire, spade or 4mm connectors. Most good quality speaker cables have some indication, such as colour coding or ‘ribbing’ on the insulating material, indicating which conductor is ‘+’ or positive.
