TIW 360 8 OHM

Characteristics and sound properties

For those who feel that the ATLAS DSM MK III is just too high and too wide, the ATLAS COMPACT MK III could be just the thing. The aim here was to slim down the size of the cabinets without compromising the excellent sound characteristics of the ATLAS DSM MK III. If you want to cut down the volume of a speaker cabinet without losing too much of the lower bass range, you have to use a bass driver with a smaller diaphragm area. As far as the lower frequency extremes are concerned, the ratio of diaphragm surface area to cabinet volume is of the utmost importance. In this context, the TIW 360 8 Ohm is the ideal bass speaker and the AL 170 8 Ohm optimal as a low- to midrange unit. Of course, a 40 cm subwoofer will generate more bass power than a 30 cm driver simply because it has a larger diaphragm surface area. But the tremendous power generated by the TIW 360 8 Ohm with optimal bass reflex tuning, should easily provide sufficient bass volume for most applications. The use of the same medium and high-range cones as in the ATLAS DSM MK III ensures a close relationship in terms of sound quality with the larger model.

This, the fourth version of the ATLAS COMPACT, now boasts the latest driver highlights that the VISATON range has to offer. Apart from the TIW 360 8 OHM and AL 170 8 OHM used in the MK III version, the latest version makes use of the TI 100 8 OHM as the mid-range loudspeaker and KE 25 SC 8 OHM as the tweeter. The crossover unit has been completely redesigned and adapted to match the new drivers.

The baffle has also been changed. The wide bevels make the cabinetlook that much slimmer and prevent edge-reflexions in the more susceptible mid- and high-ranges. The bass reflex tube has also been modified. By using a larger tube, flow noise and losses have been reduced.

The ATLAS COMPACT MK IV is a very dynamic speaker with powerful deep-black bass reproduction but without getting woolly in the bass department. Additional features are absolutely neutral voice reproduction and crystal-clear high-frequency sounds without sharp edges.

It is well-known that there are two types of loudspeakers: hi-fi speakers that produce the most accurate, unaltered sound possible, and disco or musician's speakers, where the top volume level is of the utmost importance. These volume levels are normally only possible with horns but these often cause coloration of the sound. The MONITOR 890 MK IIwas designed specifically to combine the best of both worlds. In the mid-range, we use a driver & horn unit which is so dynamic and produces such undistorted music, that many a horn-disparager has had to admit that this is simply unbelievably "different". Two excellent quality woofers, TIW 360 8 Ohm, mounted in the 180 litre vented cabinet, generate a bass sound pressure that is physically tangible, as you have experienced with concert speakers. Combined with the first-rate TL 16 H 8 Ohm high-range horn, we have created a loudspeaker system that breaks down the previously unbridgeable barrier between the hi-fi and the professional speaker.
We recommend, initially at least, the following level settings: tweeter: -4 dB; mid-range: -4 dB
Thanks to the added impedance linearising unit in the crossover unit, the Monitor 890 MK II is now even better suited to use with critical amplifiers (e.g. tube amplifiers).

The SUB T-36 subwoofer was developed to complement home video and THX® systems with an active subwoofer output and can, if required, be equipped with an active subwoofer module. The driver used is the TIW 360 8 Ohm, to which a compensating magnet can be added to shield off unwanted magnetism. The 12" speaker used achieves low-range frequency extremes of 35 Hz in this relatively small 63-litre cabinet. From 50 Hz to 200 Hz, the subwoofer produces a perfectly linear frequency response and achieves the THX® requirements with its Butterworth characteristics and an attainable distortion-free sound pressure of over 105 dB at 50 Hz. Used in conjunction with an active filter, the system achieves the required cut-off frequency and filter characteristics with ease and, at the same time, produces maximum sound pressure, of no less than 113 dB with the SUB T-36. If set up in the corners of the room, an additional 9 dB can be added to the rated maximum. Thanks to the special cabinet construction, low-range bass comes across intact, clearly and yet powerfully, so that effects such as explosions are not only clearly heard, but provide the listener with a tangible realistic live feeling, too. The SUB T-36 subwoofer in conjunction with the CineTOP 170 system is recommended for medium sized to large rooms. Lying on its side it can also be used as a base for the CT CENTER 170.

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.

The VOX 300 extends the high-end VOX series upwards. While the mid-to-high-range is the same as in the VOX 252, the TIW 360 8 OHM has been chosen as the woofer for this model. As a result, while the excellent characteristics experienced in the mid-to-high range remain the same, the level accuracy and dynamics in the bass department have been increased and the lower limiting frequency reduced to a remarkable 23 Hz. The VOX 300 can, therefore, be seen as the VOX variant for high-volume aficionados who like to hear concerts at close to the original sound levels in large rooms.
