The question we asked ourselves during the development of the SUB T-25 was, "Is it possible to design a subwoofer with a minimal cabinetvolume of just 30 litres as low-range bass support for home video applications and even for medium-sized column speakers?"
The answer was a definite "yes". This was realised using a special 30 litre cabinet, the TIW 250 8 Ohm and an active subwoofer module (not included in delivery!). Inside the vented enclosure, the TIW 250 8 Ohm is mounted on the baffle, so that a front-opening port makes sense both optically and acoustically. The subwoofer is then magnetically shielded using an additional compensating magnet. The amplifier module is mounted to the rear of the subwoofer. In practice, a cut-off frequency of 50 Hz provides a lower frequency extreme of just 25 Hz. Low-range bass freaks can now add this extreme bass functionality to their existing speaker arrangement at a maximum sound pressure of 106 dB. For home video applications the cut-off frequency of 100 Hz is the right choice. With this arrangement, the ratio of low-range bass to efficiency shifts in favour of the maximum level, which is then 112 dB. The lower frequency limit still rises to a remarkable 40 Hz. If set up in the corners of the room, an additional 9 dB can be added to the rated maximum acoustic pressure. In this way, it is possible to achieve optimum bass output depending on your taste and the acoustics of the room up to the limits of the rated maximum volume. The SUB T-25 is well suited as a subwoofer for small home video applications like the CT SUB/SAT 80 or CineTOP 130. It can even be used in conjunction with the centre-speaker CT CENTER 130 and the CT DIPOL 130 to make a fullrange centre-speaker or effect speaker.
