Placement

Using as a surround speaker

Enhance the sensation of being at a live performance by giving three-dimensional sound movement to the sound effects. Place the surround speakers at the side of the listener or at a position diagonally from the listener. Ideally, speakers should be placed symmetrically.

Place these speakers so that their height is 1 meter higher than that of the listener’s ears.

The speaker cabinet is made of wood and sensitive to extreme temperatures and humidity. Avoid placing the speaker system in locations subjected to direct sunlight or in humid places such as near an air conditioner, bathroom, or kitchen.

Installing on the wall

If the speakers are to be wall-mounted, make sure that the walls are strong enough to support the speaker’s weight. The weight that mounting screws can support varies greatly depending on the wall material and the position of the reinforcing ribs embedded in the wall. Use the thickest and longest possible mounting screws with mounting screw head diameters less than 10 mm and shank diameters less than 4 mm (consult with your interior designer or contractor).

Attach the supplied cushioning pads as shown to wall-mount the speaker securely.

Installation using commercially-available stands and fixtures

The surround speaker bottom and rear are equipped with screw holes so that you can attach commercially-available stands or mounting fixtures for a variety of mounting options. (Two M5 screw holes, 60 mm pitch on the bottom and the rear.)

Note:

When attaching an accessory item to a speaker, be careful of the length of the screws used. Use only screws that provide the required strength with a screw length between 3 and 11 mm.

Use with a TV set

In general, Braun tubes used for color television sets, etc. are extremely sensitive and can be affected even by the magnetism of the earth. If a speaker system is used near them, therefore, discoloration or distortion of pictures will occur. To allow use with color television sets, etc., this speaker system is provided with magnetic shielding.

Even so, discoloration may still result, depending on the installation environment. If discoloration occurs, turn off the power of the television set, wait for 15 to 30 minutes and then turn it on again. This activates the self-demagnetizing function of the television set, improving the display condition. If discoloration persists even after performing this remedy, move the speaker apart from the television set. Discoloration may also be caused when a magnet or other magnetizing object exists near the television because of the combined effect.

Speaker care

Your Onkyo speakers are finished with a high quality covering that serves to protect the wood speaker cabinet.

Wipe the cabinet periodically with a dry, silicon-embedded or plain soft cloth.

The covering may be cleaned with a soft cloth moistened with water and a mild soap. Avoid the use of furniture polishes or harsh cleansers. Use a soft brush or hand vacuum cleaner to remove dust and lint from the grille material.

Natural wood finished cabinets

The cabinets are finished with a natural wood surface. They have a unique wood grain pattern. Your cabinets have their own raw beauty and uniqueness which is unlocked from the tree; this is depicted by the cross-grain patterns with dark and light coloring. You can enjoy Onkyo’s craftsmanship not only when designing for the best sound quality, but to assimilate natural blessings for the visual senses. The paint and finishing work of the cabinets are conducted under the strictest quality control standards.
