TIW 400 8 OHM

The ATLAS DSM MK III is a superlative column speaker - not only because of its impressive height of 1.70 m, but above all because of its acoustic qualities.
The 5-way combination employs the TIW 400 8 Ohm high-tech speakers as long-stroke woofers, TIW 250 8 Ohm 's as internal drivers, GF 200 2 x 4 Ohm 's as fibre-glass mid-bass units and the tried-and-tested DSM 50 FFL 8 Ohm and DSM 25 FFL 8 Ohm titanium cones as mid- to high-range unit.
After considerably improving the bass range in the MK II version compared with its predecessor by using the TIW 250 8 Ohm as the inner driver, the current model has been further refined as the ATLAS DSM MK III - by including the GF 200 2 x 4 Ohm as the mid-bass unit. The result is far improved pulse dynamics, leading to even more pleasurable listening especially at peak levels.
Let it be said to all owners of the ATLAS DSM MK II, that conversion to the MK III version is remarkable easy. The crossover unit of the MK II has been retained with no change. The GF 200 2 x 4 Ohm can be fitted straight into the cut-out in the baffle of the WS 21 BF and its rim will neatly cover up the existing screw holes.

The SUB T-40 subwoofer is a completely uncompromisingly good vented system for use in an active installation and complements the bass range of multi-channel systems. The cube-like cabinet with an outer edge of 63 cm and sophisticated inner reinforcements has a total volume of no less than 200 litres!!! The short sides and damping of the cabinet combine to eliminate standing waves within the scope of application of the speaker. If required, the T-40 can also be supplemented with an active subwoofermodule. The driver used is the TIW 400 8 Ohm, for which a compensating magnet is available to shield off unwanted magnetic interference. The 15" speakers mounted in this special cabinet construction with its extremely large bass tunnel enable the lowest frequency bass to be reproduced without any distortion and attains unbelievably low frequency extremes of 25 Hz. Between 30 Hz and 200 Hz, this subwoofer produces a perfectly linear frequency response, which, in conjunction with the Butterworth characteristics attained and a realistically distortion-free sound pressureof over 105 dB at 30 Hz, fulfils the THX® requirements. Combined with an active filter, the required cut-off frequency and filter characteristics can be exactly pre-set. The maximum sound pressure of the SUB T-40 is 114 dB. If set up in the corners of the room, an additional 9 dB can be added to the rated maximum.

The SUB T-40 will enable you to reproduce the lowest bass frequencies at high output levels and with no loss. The extreme cabinet stiffeners guarantee reduced resonance operation with clear-cut, powerful bass that you not only hear but feel as well. This subwoofer is the perfect choice if you want to feel the acoustic effects realistically - as if you were there!

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.
