Dear Music Lover,  
Thank you for purchasing this Dynaudio subwoofer. With it, you have  
chosen for the latest in audio technology and engineering, culminating  
into the finest in audio reproduction.  
Dynaudio is one of the very few companies who can realize such  
loudspeaker concepts through it's own in-house development and  
production facilities. These facilities are so advanced and the quality  
control is so strict that Dynaudio is likely the only speciality audio  
company to have exceeded ISO 9000 and earned QS 9000 certification.  
Each Subwoofer model is constructed by Dynaudio's master craftsmen in  
Denmark to these high standards of quality.  
With their dynamic, accurate performance and ease of integration into  
even elaborate systems, Dynaudio subwoofers are ideally suited to  
obtain maximum enjoyment from high-resolution formats such as DVD-  
Audio and SACD. These characteristics in combination with sustained  
high volume level capabilities make Dynaudio subwoofers also an ideal  
choice for demanding home theater and multimedia set-ups.  
In order to obtain the best possible performance from your Dynaudio  
subwoofer, please carefully read and follow the instructions.  
We wish you many musical and exciting moments with your subwoofer,  
Dynaudio Sub 250

To unpack the subwoofer  
1. Unpack the subwoofer on a clean, even and soft area; floor carpeting is very  
2. The packaging should be opened from the top. Remove all accessories that  
come packed with the subwoofer (such as AC power cord and grille). Do not  
remove the top part of the protective material.  
3. With the protective material still in place but with accessories removed, carefully  
tilt the packaging on its side and tilt again to turn it upside-down. Ensure that no  
part of the top-cover is obstructing the opening at the top.  
4. The outer packaging can now be lifted away from the subwoofer itself. Remove  
the protective material that now is on top. Through the polyethylene bag you can  
now see the underside of the subwoofer.  
5. Open the plastic bag and remove such from around the base of the subwoofer.  
6. Again, carefully tilt the subwoofer on its side and again to turn it onto its feet. Note  
that the top part of the protective material will now come off easily so ensure that  
the subwoofer does not drop or slide away in the process.  
Check that the contents are complete  
• Subwoofer: The factory-set power requirements (refer to label on rear of  
subwoofer) should correspond for the region where the subwoofer was  
purchased. Refer also to chapter “Important Safety Instructions” on page 2.  
• Front baffle grille.  
• AC mains lead. The supplied lead should be suitable for the region where the  
subwoofer was purchased.  
• Owners Manual.  
The subwoofer can be operated without the grille. However, it is recommended that  
the grille is mounted during normal use to help prevent accidental damage or dirt  
settling on the cone of the loudspeaker. With subwoofers, the influence of the grille on  
the sound is virtually negligible.  
To remove the grille:  
X Gently pull the grille at all corners.  
To fit the grille:  
X Line up the studs with the corresponding front baffle holes.  
X Gently push the grille in at all corners.  
Note: Be careful when mounting the grille not to touch the cone of the loudspeaker
