Use the best speaker cables you can. The length and type of speaker cable used in your system will have an audible effect. Under no circumstance should a wire of gauge higher (thinner) than #16 be used. In general, the longer the length used, the greater the necessity of a lower gauge, and the lower the gauge, the better the sound.
NOTE: MartinLogan recommends using 5 wall anchors to secure each F resco i to a wall. During the installation, if any of the screw/wall anchor positions are over a stud, it is recommended to screw directly into the stud. NOTE: T o assure that your F resco i is safely wall mounted, these instructions must be carefully followed.
