Customer Service Department for advice The performance of the subwoofer 15 directly related to its placement in the listening room and how you align the subwoofer with its satellite speakers Setting the volume of the subwoofer in relationship to the left and right speakers 15 also of critical importance because it is essential that the subwoofer integrate Smoothly with the entire system Setting the subwoofer s volume level too high will result in an overpowering boomy bass Setting the volume level too low will negate the benefits of the subwoofer Here are several additional facts on installation that may prove useful It is generally believed by most audio authorities that low frequencies below 125Hz are nondirectional and therefore placement of a subwoofer within any listening room is not critical While in theory it is true that the larger wavelengths of extremely low frequencies are basically nondirectional the fact is that when installing a subwoofer within the limited confines of a room reflections standing waves and absorptions generated within the room will strongly influence the performance of any Subwoofer system As a result the specific location of the Subwoofer becomes important and we strongly recommend that you experiment with placement before choosing a final location Placement will depend upon your room and the amount and quality of bass required for example whether or not your room permits placement of the s
