UNPACkINg ThE SPEAkER
CAUTION: The S3900 weighs 39.2kg (86.3 lb). To avoid personal injury or damage to floors or the speaker,
we strongly recommend that at least two people unpack and move the speaker.
The speaker has metal feet installed on the bottom of its cabinet that accept the supplied spiked inserts. To avoid
damage to your floor, we strongly advise that you unpack the speaker on a well-protected surface, such as a thick
carpet or a thick piece of cardboard.
TO UNPACK THE SPEAKER:
1. Open the box flaps.
2. While standing on the box’s lower flap, gently rock the speaker and its packing back and forth while pulling it out
of the carton. In this way you can “walk” the speaker out of the carton. It helps to have a second person hold the
carton steady from the back side.
3. Once the speaker is out of the carton, remove the upper and middle pads. The speaker’s accessories are packed on
the top end of the upper pad, so be careful not to discard them.
4. With another person’ s help, carefully tilt the speaker on its side onto a thickly carpeted or well padded surface.
5. Remove the tape on the bottom of the cloth bag, slide the open end of the bag up on the speaker and remove the
bottom pad.
6. Tilt the speaker back up on its feet and remove the cloth bag.

speaker one way, so please note the proper orientation of the grille pins before re-installing the grille on the speaker.
