Characteristics and Sound Properties
Note - only Fontanella SAT are in this kit. The FONTANELLA subwoofer (optional) satellite system is both visually and acoustically a completely new experience. The drivers in the satellites are arranged to project the sound upwards. Two specially shaped cones reflect the sound according to specific patterns to ensure that the sound is distributed horizontally and uniformly in all directions.
The mid-bass unit is the AL 130 M - 8 Ohm, and the tweeter range is covered by the DT 94 - 8 Ohm.
This diffused sound distribution means that the impressive spatial effect is virtually uniform all round the room. Virtual sound sources, for example the voices or instruments that appear between the speakers, can be clearly and precisely located. The depth of colour of the sound remains the same at any seating position in the whole room. Ideally, the satellites should be positioned 0.5 m to 1 m away from a wall and on a base or stand. The cones should then be at ear level or slightly below.
The passive subwoofer cabinet has been designed to match the satellites and is fitted with the GF 200 - 2 x 4 Ohm double voice-coil woofer; resulting in powerful, highly dynamic bass reproduction from this high-end driver. The FONTANELLA system provides a high level of listening pleasure as a hifi stereo system but is also extremely well suited to use as the rear effect channel in home-video systems. In such cases, the subwoofer is not required and the two satellites are used alone.

Assembly
The Fontanella Sat cabinet consists of 8 side pieces 16 mm thick with bevels and a base and top both octagonal and made of 19 mm material.
First, cut out the openings in the base and top. Then the side pieces and base are glued together. Before fitting the top, cut out and finish the four openings in the sides for the fixing points and connection points for the upper part. Then glue the lid in place. The frequency crossover unit is on the connection terminals and is fitted in the base, along with the bass reflex tube.
The mounting sets can now be fitted. These comprise four parts (terminal posts, consisting of an inner part, an outer part, a disk and spacer posts) which are screwed together. One of the outer terminal posts is red, the other is black. These two terminal posts are used at the same time for connecting up the tweeter. To this end, feed two wires from the tweeter output of the crossover through two separate 7.5 mm holes side-by-side in the lid and solder them to the spacer posts of the colour-coded mounting set (red (+) / black (-)). Then insert all four assembled mounting sets in the holes in the lid, ensuring they are firmly seated.
The upper section of the speaker consists of one large cone over the low- to midrange speaker and a smaller one over the tweeter. The large cone is connected to the bass cabinet via the mounting sets and brass rods. Two of these brass rods also serve as signal carriers to the tweeter which is mounted in the large cone. Two short wires (approx. 5 cm long) are soldered to the tweeter and two of the rods. Take care to ensure that you solder the wires to the right rods - these must be the ones which are connected via the mounting sets to the crossover in the cabinet. The entire upper section can now be mounted on top of the cabinet.
Finally, the small tweeter cone is stuck onto the diffuser of the tweeter.
Internal Damping
Half a mat of damping material is used for each satellite cabinet.
