Please refer to the illustration for the ideal angles and positions of each loudspeaker in your surround system. The loudspeakers should be distanced from the wall according to the requirements of the loudspeaker. However, due to AV receiver crossover filter settings, they may be positioned closer to the wall. Experimentation is advised. If setting up a 5.1 system, you should place your surrounds in position (A).
If setting up a 7.1 surround system, you should place your side speakers in position (B) and rear loudspeakers in position (C) to create a full 360° soundstage.
If the sound is too bass heavy or there is a bass boom from the room when playing music (without a subwoofer), try moving the loudspeakers slightly further away from the wall(s). In a system with a subwoofer, try adjusting the crossover frequency settings for the loudspeakers and/or subwoofer or changing the subwoofer’s position. If placed in a corner, the subwoofer can overexcite certain room modes.
If there doesn’t seem to be much bass from the system, check what the AV receiver has set the speaker size to. If the loudspeakers have been set to large as part of the auto setup, try setting them to small, which will send more bass frequencies to the subwoofer. Also check the crossover frequencies of the loudspeakers and subwoofer, as well as the individual channel levels.
The Platinum C250 3G centre channel should be positioned so that it is pointing at the viewing position and at approximate ear height.
