[. . . ] If they're fed any of the following signals, even if the input power is within the specified rating, excessive current may flow in the speaker coils, causing burning or wire breakage: 1.

En Getting to Know the Speakers Using the Included Cork Spacers You can improve the sound quality by attaching the included cork spacers to raise the speakers off the surface and reduce the contact area. The cork spacers also make the speakers stable and prevent them from slipping.

Using Close to a TV or Computer Connecting the Speakers TVs and computer monitors are magnetically sensitive devices and as such are likely to suffer from discoloration or picture distortion when conventional speakers are placed nearby. In this case, turn off your TV or monitor, wait 15 to 30 minutes, and then turn it back on again. This normally activates the degaussing function, which neutralizes the magnetic field, thereby removing any discoloration effects. If discoloration problems persist, try moving the speakers away from your TV or monitor. Note that discoloration can also be caused by a magnet or demagnetizing tool that's too close to your TV or monitor. Note: If the speakers are placed close to a TV or monitor, due to the electromagnetic waves radiated by the TV or monitor, you may hear noise from the speakers even after your amplifier has been turned off. Stubborn stains can be removed by using a soft cloth dampened with water and a mild detergent. Do not use abrasive cloths, thinners, alcohol, or other chemical solvents that may damage the finish. Speaker Placement The sound quality of the speakers is directly affected by the size and shape of the room they're used in and its furnishings. When considering where to place your speakers, read the following: · Where possible, mount the speakers on speaker stands, concrete blocks, bricks, or a sturdy bookshelf. Putting them directly on the floor will emphasize bass sounds, creating a boomy sound. · If a speaker is placed on an uneven surface where it can wobble or vibrate, bass performance will be adversely affected. You can eliminate speaker wobble by putting a shim made out of cork or metal, such as a coin, underneath the speaker or stand, as shown. Shim · If you mount the speakers on a flat surface, such as a bookshelf, you can improve the sound quality by inserting cork spacers or coins in between the speaker and the shelf. Raising them off the surface like this will reduce the contact area and improve the sound. · If you like lots of bass, mount the speakers on low speaker stands and place them in front of a solid wall. To achieve a good stereo sound, put the left and right speakers in similar locations at the same distance away from your listening position and at the same height. [. . . ] To achieve a good stereo sound, put the left and right speakers in similar locations at the same distance away from your listening position and at the same height. If you put them in totally different locations, for example, one on the floor and the other on a bookshelf, the stereo imaging will be adversely affected. · To determine the best positions for your speakers, imagine an equilateral triangle and put the left and right speakers at the ends of the base.
