13 cm (5") HiFi low-midrange driver with coated paper cone, elastic rubber surround and 25 mm voice-coil. Suitable as woofer and due to the very balanced frequency response also as low-midrange driver especially in large 3-way speaker systems.

Characteristics and sound properties
Our CT DIPOL 130 is a dipole loudspeaker conforming to the THX® regulations for positioning close to walls. As a result of the special characteristics of this dipole, a completely free-standing diffuse sound field is generated. The system uses two mid-bass W 130 S 4 Ohm and two 25 mm titanium SC 4 ND 4 Ohm dome tweeters with neodym magnets. In the medium and high-range, the opposing loudspeakers operate from separate enclosed chambers that are phase shifted by 180°. Up to a frequency of 200 Hz, the mid-bass drivers work in sync. This is possible because of the special crossover circuitry, to ensure that, in the bass range, and despite the dipole principle, sufficient sound is produced. According to the THX® regulations, such a dipole system must cover a frequency range of 125 Hz - 10,000 Hz. The CT DIPOL 130 achieves this with no effort, as it does the maximum sound pressure requirements of 102 dB. The designers placed emphasis on high impedance, so that the speakers can be connected up to virtually any amplifier with no problems. The CT DIPOL 130 can, however, easily be integrated into normal Dolby®-Surround systems. 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 frequency ranges. As an option, two dipoles (left and right) can be combined with an active subwoofer SUB T-25 with a cut-off frequency of 100 Hz to produce the ideal surround channel system, which will cover the entire frequency range. The system experiences no trouble in achieving the high power-handling capabilities for fullrange use. The ideal position for the CT DIPOL 130 to provide ideal listening pleasure is to the side of the sitting position, either hanging on the wall about 1 m -1.5 m off the floor or on corresponding stands. The speakers can be used in all CineTOP systems, such as CineTOP 130, CineTOP 170 and CineTOP 200 for smaller and large rooms. The CT DIPOL 130 system is also an optimum choice for improving an existing home video system. This Dipole is characterised by its excellent diffuse sound field that will surround the listener with a carpet of sound. The tangible yet not locatable spatial effects will turn your sitting room into a cinematic experience.
