This compact centre speaker will find a suitable space in the shelving just above or below the TV set. It is fitted with two W 100 SC 4 Ohm 's connected in series, which produces a total impedance of 8 ohms. As a result, the CT CENTER 100 can be used in conjunction with receivers that have problem communicating with low-impedance speakers. Up in the high-frequency range, the G 25 ND 8 Ohm, a 25 mm textile dome unit with a Neodym magnet, performs well. The tweeter is arranged asymmetrically between the woofers in order to achieve an enhanced horizontal radiation pattern. All the drivers are, of course, magnetically shielded to prevent annoying interference effects on TV screens.
Apart from the CineTOP 100 combination consisting of 2x CT MAIN 100, 1x CT CENTER 100, 2x CT DIPOL 100 and the active subwoofer, it is also possible to combine the Centre and Dipole speakers with small or medium-sized upright speakers such as the ALTO II, ALTO III C or ALTO LINE. As subwoofer, the SUB W-20.39 would be a suitable choice.
This dipole speaker makes use of two W 100 S 4 Ohm and two G 25 ND 8 Ohm textile dome units. The idea of dipoles is to create a diffused sound field from the effect channels. For this reason the tweeters at the front and rear are cross-connected. The all-pass circuitry in the deep-bass department ensures that, at frequencies above 200 Hz, the woofers are also cross-connected, and below that level they work in synch. This prevents the bass completely cancelling itself out. The two dipoles should be positioned at both sides of the listening position and just above ear-height or mounted on the wall at that height.
Apart from the CineTOP 100 combination consisting of 2x CT MAIN 100, 1x CT CENTER 100, 2x CT DIPOL 100 and the active subwoofer, it is also possible to combine the Centre and Dipole speakers with small or medium-sized upright speakers such as the ALTO II, ALTO III C or ALTO LINE. As subwoofer, the SUB W-20.39 would be a suitable choice.
For use as a small satellite, the CT MAIN 100 is equipped with a pair of W 100 S 4 Ohm and the G 25 ND 8 Ohm textile dome unit. The two woofers are connected in series, which produces a total impedance of 8 ohms. As a result, the CT MAIN 100 can be used in conjunction with receivers that have problem communicating with low-impedance speakers. The drivers are arranged symmetrically on the baffle based on the D'Appolito principle, where the oval front panel of the tweeter leaves only very little space between the woofers.
The CT MAIN 100 can be used as the main speaker in a multichannel system (e.g. CineTOP 100 combination using 2x CT MAIN 100, 1x CT CENTER 100 and 2x CT DIPOL 100, boosted with an active subwoofer), or as the satellite in a stereo system. As subwoofer, the SUB W-20.39would be a suitable choice.
