CELES TION

Introduction

Since 1924 Celestion has been associated with technical innovation coupled with design
and manufacturing excellence.

Located in Ipswich. Sultolk. a county famous for its gentle rolling landscapes and home
of England '5 greatest landscape artist, John Constable. Celestial) continues its proud
traditions.

Traditional skills are caretul/y maintained but are now harnessed to the precision of new
technology. A unique laser interferometry measuring system enables our research
engineers to develop transducers whose behaviour can be precisely controlled The
result is carefully integrated loudspeaker systems which ensure outstanding performance
and lifelong reliability for your listening pleasure.

Please pause for a few minutes to read the following notes before beginning to listen.

Unpacking and Aftercare

Your loudspeakers have been designed to a very high standard of performance and finish.
The tough. attractive vinyl surfaces may be polished or sponged with a little warm. soapy
water. if you use aerosolpotish then please sprayonto a cloth and keep all oversprayaway
from the grille and the drive units beneath.

Alter unpacking. we suggest you retain all the packaging since you may need to transport
them at a later date.

If you need to brush the grille fabric on the loudspeaker we recommend that you remove
the grille to do so. Grasp the outer edges of the grille and apply firm pressure against the
cabinet to effect easy removal.

Please avoid touching the cone of the bass unit since it is delicate and easily damaged.
Remove build-up of dustgentlyblowing from time to time. The tweeter unil domes should
also not be touched. Dust only by blowing and on no account attempt to touch the treble
dome behind its protective grille. since this will damage the dome and spoil its
performance.

DL12 Series Two

Please note we strongly recommend you use the plinth but it is not essential. If you do
decide to use it. please read on.

Unpacking and Bill/ding Up (you DO NOT need to drill the cabinet or plinth).

Great care should be taken. In each of the DL 12 Series Two boxes you will find one speaker
cabinet and one plinth. Taped to the underside of the plinth will be four short dowels for
attaching the speaker cabinet to the plinth. Having removed all the plastic bags. lay the
DL 12 Series Two speaker cabinet on its back with the grille uppermost. taking care not
to lift orhandle the loudspeaker by the grille. Lay it an a carpeted floor to prevent marking
it and place the plinth next to it, recessed side down. You will see four pie-drilled holes

on the top; locate each dowel and lap in gently with a hammer or mallet to the end stop.
Tip the speaker on its end by lilting up the end closet to the Celestion badge: it should
now be standing upside down (the badge on the Grille will now be near the top of the
loudspeaker). You will see four'pre-drilled holes on the bottom of the cabinet lacing you.
Take the plinth and address it to the cabinet. making sure all four dowels locate in the holds
(if they do not, rotate until they do). Only when the plinth is located. very gently tap in
rotation approximately where each dowel is located until the top of lite plinth meets the
bottom of the cabinet.

Once this is done and youare happy tltatit is firmlyioined, lay the speakeron its backagain
and tipping it on to the plinth into the upright position. The Celestion badge will be near
the bottom of the grille. Move the speaker to the approximate room position and repeat
for the other speaker. taking time and care.

Roam Positioning for the 0L4 and 0L6 Series Two

These loudspeakers have been designed to operate on rigid stands close to the rear walls.
Bass reinforcement resulting from this placement has been taken into account in the
design. Celestion recommend using high rigid column stands loaded with sand or lead
shot.

Position the speaker/stand combination close to the rear wall but not closer than 2'
{50mm} to it. If you are going to be using them on bookshelves, then make sure the front
of the speaker is level with the front of the shell. The position from the side walls should
be not less than 24 ' (61cm), set obliquely at about 30 degrees. ideally the loudspeaker
should be placed approximately 6 feet (193cm) to 9 feet (274cm) apart.

Mounting the speaker on wall brackets is acceptable but NEVER screw to or through the
speaker cabinet when fixing in this way.

Room Positioning for but Series Two

The 0L8, being a larger speaker, is balanced to work on a rigid column stand about 18'
(46cm) high and at least 18' (46cm) away from the rear wall. The stand should also be
loaded with either sand or lead shot. The position from the side walls should be not less
than 24' (61 cm), set obliquely at about so degrees. Ideally the loudspeaker should be
placed approximately 6 feet {183 cm) to 9 feet (274 cm) apart.

Celestion Stands

To ensure maximum performance from your DL loudspeaker system, a stand has been
developed. Supplied in a sell assembly flat pack. a rigid aluminium extruded centre
column is secured to substantial steel top and bottom platforms with high tensile bolts.
Adjustable spiked feet are supplied and a recessed rear centre chanrtel carefully conceals
the loudspeaker cable - a clever design feature. High density polythene inserts are
supplied for sand or lead shot damping. There is a choice at either an 18 (46 cm) (L 8 18)
or 24' {61 cm) (L824) stand height to ensure optimum listening.

For the ultimate performance when using stands. a number of aspects must be borne in
mind. The stand should be placed on the floor using the adjustable spiked feet. which
should be set to give firm level foundation. The spikes are intended to penetrate normal
