UNPACKING INSTRUCTIONS

Your Estelon Model YB loudspeakers come packaged each in a
carton box. For shipping, both boxes are packed in a plywood crate – we
strongly recommend keeping the original package for possible future
use / transport. The crate is collapsible for easier storage.

Bring the crate for unpacking as close as possible to the speakers
positioning point*. Due to the substantial weight and slippery surface
of the loudspeakers we suggest that two (2) people assist in the
unpacking and positioning of them for listening.

Contents of the crate:

•

Pair of loudspeakers / 2 boxes:
o Left unit / 1 box
o Right unit / 1 box
o 2 Pairs of gloves and 1 Polishing Cloth

Each Loudspeaker box contains:

•

4 feet (in the bottom of the loudspeakers)

•

3 grills
o 1 Woofer grille
o 1 Mid-Woofer grille
o 1 Tweeter grille

•

1 Cloth bag to protect speaker nish

* Recommended positioning point:
The positioning of the speakers in the room must be symmetrical for

achieving a balanced sound stage – this is very important in a narrow room.
Expect the distance between the speakers to be approximately 2 – 5 m,
depending on the size of the room and its reverberation characteristics.

A “smooth” back wall will minimize imaging distortions. The

distance between the back wall and the speaker should not be less than

0.5 m, the distance from the tweeter to the back and side walls must not
be too similar.
