POSITIONING THE SUBWOOFER

stored settings has been overwritten with your new settings.

•To avoid accidental over-writing of presets, set the Preset/Settings switch on the subwoofers back panel (No. 8 in fig. 2) to the "Protect" position. Adjustments on- the-fly for all settings are still possible.

To recall a Preset:

• Simply briefly press the desired Preset button A, B, C or D.

• Presets can only be stored or recalled in "Master" mode.

•Program one preset with the best global settings for your system and use this as the starting point to program the other presets. This way you always have a starting and reference point.

Introduction

Although it is often said that the location of a subwoofer in a listening room is not critical (as the human ear can not locate direction at very low frequencies) we recommend that you choose its position carefully so the subwoofer can integrate fluently with the other speakers in the system and interact in the correct way with the acoustical environment.

All of the following should be taken as rule-of-thumb guidelines; bass response in general is very dependent on the acoustics of the listening environment. Finding the best position often involves a lot of trial-and-error experimenting. Always trust your ears, even if seemingly the position of the subwoofer goes against the guidelines. Contradictory as it may seem, good integration of subwoofers has been achieved when one isn't aware that a subwoofer is present at all in the system, yet performance involves fast, deep and solid bass without sounding stressed, even at loud levels.

•Trying to find the right location will also involve finding the right settings such as Level, Cross-over frequency and Phase for that location. The subwoofers presets will prove to be a useful tool when trying to find a suitable setting: You can store the settings that match a particular position so you can easily swap between locations. It will also allow you to make small changes in settings and to store these as separate presets. This way, you can compare between presets to find the best setting. Refer also to section "Storing and recalling a Preset" in Chapter "Adjusting and Using the subwoofer".

•When experimenting to find the optimal location, use a couple of music tracks with repetitive bass across a large spectrum. The tracks should be sufficiently different from each other and each should cover a wide bass-range. Musical instruments, such as a double-bass, bass guitar, church organ, etc. cover a wide spectrum in the bass region and are therefore very suitable. Using non-music (such as action movies) material to position and adjust the subwoofer with, may lead to spectacular results with such material but almost always it will result in overblown and excessive bass when playing music with the same setting. Remember that the Dynaudio subwoofers allow for 4 different preset settings, so you can store a preset with the setting that matches the occasion (be it for action movie or music listening) best.

Every listening environment will have specific "room- modes", whereby in some specific locations in the room and at particular frequencies, the bass may be too much or too lean. This effect will be stronger in square and "shoe- box" shaped rooms. With a single subwoofer, the better position for the subwoofer relative to the listening position will be the one where bass is perceived to be neither too much or too lean at any given frequency.
