Introduction

First of all, we would like to thank you for choosing ADAM Audio!

ADAM Studio Subwoofers are built to a maximum in reproduction quality and perfection. To

enjoy the capabilties of your new subwoofer please read the following hints and considera-

tions, as the positioning and the acoustical properties of the control room often play a bigger

role than you might think.

General recommendations for the Setup:

• Thesubwoofershouldbepositionedonarmground.Vibratingpartscanmaskthesound;

there is not necessarily a clear distortion to be heard.

• Itisrecommendedtopositionthesubwooferbetweenthefrontspeakers,ifpossiblewith

a minimum distance of 20cm to the back wall.

• Avoidtopositionthesubwooferin a corner. Duetoaresultingphysicalpeakin the

frequency response there will always be a tendency for resonances and boominess.
