room itself. The goal is simple: to achieve consistently excellent results in the real world of the owner’s home. After all, that’s all that really matters. -
Page 9: Un-Crating & Installing The Ls3/4
Un-crating & Installing the LS3/4 Your new Wisdom Audio Wisdom Series LS3 or LS4 in-wall speaker is a sub- stantial piece of equipment. Please exercise caution when unpacking your LS4 to ensure that you do not strain yourself from its (perhaps unexpected) weight. - Page 10 The wall bracket must be attached to at least one stud in the wall, using the lag screws provided, as shown in the illustration below. Once the bracket is securely fastened to the wall, the LS3 or LS4 may be lifted up and on to the interlocking cleat system that holds it. (We recommend 3-4 people be involved in the step, as the LS4 weighs in at a little under 300 pounds (about 135 kg).
- Page 11 Once in position, use the included security screws on each side of the speaker to lock it into place in its bracket. These screws ensure that the speaker cannot come off the bracket, even in the event of an earthquake The connections to the speaker may be made either before or after the speaker is hung on its bracket.

Page 12: Room Acoustics & Placement
Room Acoustics & Placement Wisdom Audio believes in equalization. Assume for a moment that you had a “perfect” loudspeaker: as soon as you place it in your room, its perfection is gone. In fact, even good rooms often introduce deviations of 20 dB to the re- sponse of the system, particularly at low frequencies. -

Page 17: Optimizing The System
Optimizing the System A Wisdom Audio loudspeaker system is just that: a system, designed to provide the highest calibre of performance, in the widest variety of possible settings. As such, simply connecting all the wires does not mean the system is optimized. -
Page 18: Care & Maintenance
Care & Maintenance To remove dust from the cabinet of your LS4, use a feather duster or a lint-free soft cloth. To remove stubborn dirt and fingerprints, we recommend isopropyl alcohol and a soft cloth. Lightly dampen the cloth with alcohol first and then clean the surface of the LS4 with the cloth. -
