The ATLANTIS has been consistently designed for optimum sound-pressure rating while retaining a moderately sized cabinet and an elegant appearance. In the bass range, two AL 170 - 8 OHM are mounted in parallel but in separate housings, where each has about 27 l of air space to itself. These speakers have a lower limiting frequency of 28 Hz meaning that they generate good, solid deep bass. Where you position the speakers is more or less a matter of choice, but they should not be right against the wall (a minimum of 10 cm is needed) as otherwise the effect of the bass reflex tubes will suffer.
Compared with the 'normal' AL 130 - 8 OHM, the AL 130 M - 8 OHM is equipped with a shorter voice coil. This improves efficiency and makes it the ideal choice in this combination.
Used as a tweeter, the KE 25 SC - 8 Ohm is activated from 2500 Hz. The distortion factor of this ceramic dome driver is really low at these frequencies, so that even high volume levels come across completely free of distortion.
The FONTANELLA subwoofer satellite system is both visually and accoustically a completely new experience. The drivers in the satellitesare 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.
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 satellitesshould 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 satellitesand 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.
With its CONGA Visaton has produced a "big brother" to accompany the classic 3-band combinations such as the CLASSIC 200 or CLASSIC 200 GF. With a cabinet volume of 85 litres and the 25-cm subwoofer drivers mounted on the front, this column speaker is an impressive eye-catcher.
The external appearance is underlined by the solid bass foundations provided by the TIW 250 XS - 8 OHM. This high-end woofer masters the art of powerful, responsive surges of bass just as efficiently as more restrained and subtle bass accompaniment.
The AL 130 M - 8 OHM, the specially modified version of the popular AL 130 - 8 OHM designed to produce higher sensitivity in the mid-range, continues the virtually linear frequency response seamlessly at a high level.
The KE 25 SC - 8 OHM tweeter, which cuts in at 3500 Hz, has no difficulty at all producing brilliant, crystal clear treble, even at high volume levels, which is why this ceramic dome driver is so ideally suited to rounding off the upper end of this powerful 3-band combination.
Well aware that the following statement may polarise opinions: the CONGA speakers are real men's speakers.
