The TL-SUB subwoofer is a special system for reproducing lowest-range bass frequencies accurately at subsonic levels. There are software effects around that produce frequencies of 20 Hz and even less. You just have to think of the almost proverbial sound effects of the Tyrannosaurus Rex in Stephen Spielberg's Jurassic Park.
If you are prepared and able to give up about half a cubic metre of sitting-room space and are even thinking of rearranging the furniture, the TL-SUB with its ultra-low bass is just what you are looking for. One thing has to be said right from the start: the bass churned out by this system at the lowest octave level is by no means the thumping disco bass that hits you right in the stomach, but is, on the contrary, as smooth as cream. It is not locatable in the room and is felt as a sort of air movement that makes your trouser legs move. The ultra-low bass give you a fascinating feeling of being there live - provided, of course, the software has the channel programmed into it.
As regards the speaker construction, we have a new double transmission line equipped with a TIW 360 8 Ohm and a TIW 400 8 Ohm. If required, compensating magnets are available for these drivers to shield them magnetically. By not damping the cabinets, tremendous efficiency has been achieved, which, if the speakers are positioned in the corners, will attain levels of 114 dB at 20 Hz and a maximum sound pressure of 121 dB from 30 Hz. The output level is restricted by the mechanical construction of the speakers, to prevent the mechanical load from exceeding 200 W. We recommend combining the system with an active subwoofer module with a cut-off frequency of 50 Hz and, preferably with a subsonic filter in the pre-amp to protect the loudspeakers against mechanical overloading below 15 Hz.
This definitive lowest-range subwoofer is also suitable for supplementing larger home video applications such as CineTOP 170 / 200 or VOX for large rooms and small cinemas. The subwoofer can equally well be positioned upright in a corner of the room or lying in front of a wall of the room. It might be said that the reproduction of that last octave of bass sound is something of a luxury, considering the expense, but real music and home video aficionados will welcome the uncompromising approach of this system. The TL-SUB generates "deep black" bass that will set the house rocking on its foundations and turns films that use this technology into unforgettable experiences.
