SUBWOOFER PLACEMENTS

A powered subwoofer delivers crucial impact in a home theater system although it is one of the least demanding speakers to position. Since low bass frequencies are omni- directional, you can usually place your subwoofer just about anywhere in your home theater room and still get good results.

Placing your subwoofer near a wall will generally produce more output due to wall reflection. Moreover, if you place your subwoofer in the corner, the output is maximized even moire. Keep in mind that even though the bass increases as you place the sub near a wall or corner, the quality of bass may be slightly "boomier" and less controlled. Thus, aim for a spot where you get a compromise between quality and quantity of bass.

One cool technique for placing for your subwoofer is to put your sub in your listening spot (i.e. on your sofa), play some music, move around the room, and listen. Be sure that you bend down closer to the floor as you walk as this will lead to more accuracy as to what you will get. You will probably notice that the bass sounds a little bit different as you move around the room from one location to another. When you reach a spot where the bass sounds best, that may be the location where you want to place the subwoofer.

After finding the best subwoofer placement, you will need to set the phase. Earthquake subwoofers are equipped with 0° - 180° phase control switch. Simply play one of your favorite songs and switch the phase control back and forth. You may need assistance from a friend or family member. Choose the setting that produces the most bass while all your speakers are playing.

Subwoofers have slower responses compared to the rest of the speaker systems. This is strictly Physics. The CP-8 is designed to address this issue. By making the CP-8 slim in profile, it opens up more placement options (i.e. under or behind the sofa, vertically standing against the wall in the corner of the room, etc.) to offset the response delay.

Figure 6 through 9 illustrate the bass response in the room when placing the CP-8 in different location of the room.
