CT CENTER 130

The CT CENTER 130 has been specially developed with a particular driver arrangement in mind to provide perfect omnidirectional sounddispersion and to ensure the sound source is close to the image. Spoken dialogues can thus be directly located and correctly positioned even 30° from the centre line without distortion. The W 130 SC 4 Ohm loudspeaker model and the 25 mm SC 4 ND 4 Ohm titanium tweeter with its neodym magnet are magnetically shielded. The sealed 2-way speaker, with only 8 litres net cabinet volume, has a Q-rating of 0.7 and a linear frequency response of 100 Hz to 20,000 Hz. If used, as recommended, at 100 Hz at above, it can easily manage maximum levels of 105 dB. During the development of the system, care was taken to ensure that the high rated impedance allows its use with virtually any amplifier. If the speaker is not supplied with an amplifier signal which is trimmed under 100 Hz, it is advisable to add the recommended passive high-pass filter, in order to prevent overloading at higher output levels in the lower bass frequencyranges. As an option, it is possible to combine the CT CENTER 130 with an additional SUB T-25 active subwoofer with a cut-off frequency of 100 Hz which produces a high-grade centre system, which covers the entire frequency range, has excellent power handling capabilities and still remains very compact, enabling it to be easily positioned. The CT CENTER 130 can be used in all CineTOP systems, such as the CineTOP 170 or 200 for normal sitting-room use. If placed upright, the CT CENTER 130 can also be used as a main loudspeaker for compact home video applications, where it would require the support of a subwoofer, e.g. SUB-T 25. The CT CENTER 130 is characterised by its excellent omnidirectional sound distribution and balanced sound qualities, that reproduce film soundtracks in all their colour and depth.
