13. g these instructions you can improve the sound of your system The Bass Optimization System Goal Itis a fact of audio that what we hear at low frequencies is determined as much or more by the listening room than by the loudspeaker itself Placement of the loudspeakers and listeners and the acoustical characteristics of the room surfaces are all important determinants of bass quantity and quality In most practical situations there is little that can be done about this except for patient trial and error repositioning of the loudspeakers and listeners Usually the practical constraints of a living space and the impracticality of massive acoustical treatment mean that equalization is the only practical solution Professional sound engineers routinely employ sophisticated measurement systems and equalizers to optimize speakers to the installation This was never practical for the home audiophile This is why the Bass Optimization System was created It enables you to identify the dominant low frequency response characteristic of your room Once you know the problem the Bass Optimization System provides the tools needed to optimize the low frequency characteristics of the speakers to the room they are in exactly as the professional sound engineers do it Preparations Before beginning the bass tests please check the following Make sure all three Bass Optimization System controls on the subwoofer are turned fully clockwise Make sur

18. ty s Customer Service Department for advice The performance of the subwoofer is 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 is also of critical importance because it is essential that the subwoofer integrate smoothly with the entire system Setting the subwoofer s volume lt SUB level too high will result in an overpowering boomy bass Setting the volume level too low will negate the benefits of the subwoofer C J lt ue Here are several additional facts on installation that may prove SPEAKER 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 itis 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 PRIMARY room will strongly influence the performance of any subwoofer LISTENING system As a result specific location of the subwoofer becomes AREA 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 qualit
