to prepare to operate on the Sphere carefully follow these steps

Turn the Sphere and hold the metal base

rmly to move it.

Place the Sphere upside down on a

surface protected by a proper cloth to

keep it vertical and avoid possible

scratches.

Remove the Sphere from the packaging or lift

it from its position, making sure to leave the

deector on a safe position.

1 > Using the Allen Key #3(B) unscrew

the 4 M5X30 screws and remove the

frame protecting the coaxial, making

sure to always unscrew the screw oppo-

site to the previous one.

2 > The coaxial remains untied as

well. Lift the coax and turn it over the

inner ange of the Sphere.

3 > Desolder the quadripolar cable from

the four connections on the coaxial spea-

ker, quickly enough to avoid thermal

damage to wires and internal connections

of the driver. Be sure to remember the

colors of the phases. (Brown > +Woofer;

Green > -Woofer; Yellow > +Tweeter;

White > -Tweeter)

4 > Remove the coax. Remove the

acoustic dumper holding in place the

acoustic foam “candy” that contains the

crossover IP65 waterproof box and take

the “candy” out.

2.0 > Assembly Procedure:

1.1 > Crossover Board Removal:

1.2 > Crossover Cables Removal:

1 > Open the box with the Phillips screwdriver (C)

2 > Desolder the six connections using the welder (H).

Remember the phases.

1 > Open the box with the Phillips screwdriver (C)

2 > Desolder the six connections using the welder (H). Remember the phases.

3 > Unscrew the sealed cable glands (y) using the two at wrenches #17 (E) and pull the cables out.

3 > Unscrew the 4 screws (x) securing the board to

the box and remove the board.

5 > Using the cutter (A) remove the

nylon cable ties closing the “candy”,

unroll the acoustic dumper to make

possible any intervention in the

crossover box. Open the box and

desolder the bipolar cable.

(For proper interventation on crosso-

ver box and board please refer to next

paragraphs 1.1 and 1.2)

6 > Remove the crossover IP65

waterproof box. Slip the bipolar cable

out from the Sphere’s body. Now the

base is detached from the body and

can be removed/replaced.

1 > IMPORTANT: the base comes alrea-

dy cabled, with the protecting net and the

heat-shrinking sheath securing it.

Insert the bipolar cable into the Sphere’s

body throughout the proper hole.

Rests the base on the sphere, making sure

that the holes on the base ange coincide

with the ones on the body ange.

2 > Open the crossover box and solder

the bipolar cable. (For proper interventation

on crossover box and board please refer to

following paragraph 2.1).

3 > Once you are done, close the crosso-

ver IP65 waterproof box adn wrap the acou-

stic dumper sheet around it so that it looks

like a “candy”.

4 > Seal the acoustic dumper

wrapping by closing it with the two

nylon cable ties.

6 > Place the coaxial over the inner

ange, overturned with the connectors

visible and insert the silicone gasket over

the coaxial basket. Stagnate the connec-

tors and the quadripolar cable and then

weld the contacts (welder temperature

400°C) on the coaxial, quickly enough to

avoid thermal damage to wires and internal

connections of the driver. Be sure to

remember the colors of the phases.

(Brown > +Woofer; Green > -Woofer;

Yellow > +Tweeter; White > -Tweeter)

7 > Overturn the coaxial matching the

holes in the basket with the holes in the

inner ange. Position the protecting

frame on top of it, still matching the

holes, place the 4 M5X30 screws and

the "Schnorr" (L) washers in the holes of

the frame and using the Allen key #3 (B)

turn the screws counter-clockwise until

you hear a click that indicates the

correct insertion of the rst thread of the

screw in the threaded seat. Then

tighten the screws by turning clockwise

crosswise (always tighten the screw

opposite to the previous one) until you

start feeling resistance.

1 > Place the board inside the box and secure it to the box by screwing the four

star screws (X), paying attention not to force the plastic thread.

2 > Arrange the internal wires according to the attached image, in order to avoid

inappropriate contacts between wiring and crossover components.

3 > Solder the six connection points respecting the colors of the polarities

(welder temperature 400° C).

4 > Close the box cover tightening the four star screws.

3.1 > Sphere Base Replacement:

Follow steps 1 > 6 of “1.0 Disassembly Procedure” and then steps 1 > 7 of “2.0 Assembly Procedure”

Follow steps

1 > 6 of “1.0 Disassembly Procedure”, then steps 1 > 3 of “1.1 Crossover Board Removal”, steps 1 > 5 of “2.1

Crossover Board Assembly” and nally steps

2 > 7 of “2.0 Assembly Procedure”

3.2 > Coaxial Speaker Replacement:

Follow steps 1 > 3 of “1.0 Disassembly Procedure” and then steps 6 > 7 of “2.0 Assembly Procedure”

3.3 > Crossover Board Replacement:

5 >

Check the cover tightness (accurate resting on its seat) and the cable glands (making sure cables

have no clearance or air leakage).

6 > Desolder the bipolar cable from its connection in the crossover board (Z)

and remove the crossover box.

1 > Using the Allen Key #3(B) unscrew

the 4 M5X30 screws and remove the

frame protecting the subwoofer, making

sure to always unscrew the screw oppo-

site to the previous one.

The subwoofer remains untied as well.

Lift it and turn it over the inner ange of

the Sphere.

2 > Desolder the bipolar cable from

the two connections on the subwoofer,

quickly enough to avoid thermal damage

to wires and internal connections of the

driver, and remove the subwoofer.

7 > Place the subwoofer over the inner

ange, overturned with the connectors

visible and insert the silicone gasket over

the its basket. Stagnate the connectors

and the bipolar cable and then weld the

contacts (welder temperature 400°C) on

the subwoofer, quickly enough to avoid

thermal damage to wires and internal

connections of the driver. (Brown > +;

White > -)

7 > Overturn the subwoofer

matching the holes in the basket with

the holes in the inner ange. Position

the protecting frame on top of it, still

matching the holes, place the 4 M5X30

screws and the "Schnorr" (L) washers

in the holes of the frame and using the

Allen key #3 (B) turn the screws coun-

ter-clockwise until you hear a click that

indicates the correct insertion of the

rst thread of the screw in the threaded

seat. Then tighten the screws by

3.5 > Turn a Fullrange Sphere into a Subwoofer Sphere:

Follow steps 1 > 5 of “1.0 Disassembly Procedure”.

3.7 >

Upgrade a Sphere with the “Lighting Mood” base.

It is NOT possible to DIY upgrade your Sphere into a “Lighting Mood” model. “Lighting Mode” Spheres come straight out of the factory with

the light base already assembled.

3.6 > Turn a Subwoofer Sphere into a Fullrange Sphere:

5 >

Open the Crossover box with the Phillips screwdriver

(C), insert the bipolar and quadripolar cables and solder the

six connections using the welder (F). Remember the phases.

Fasten the sealed cable glands (

y) using the two at

wrenches #17 (E) to secure the cables.
