Characteristics and sound properties

The 5th generation of VISATON’s classic ATLAS COMPACT is positioned in the mid- and high-ranges and compares with the systems mentioned at the beginning of the series. Once again, we have the DSM 25 FFL 8 Ohm and DSM 50 FFL 8 Ohm dome loudspeakers. The low- to mid-range is covered by the AL 170 8 Ohm. What is new in this version is the TIW 300 8 Ohm as the woofer.

The crossover, too, has been thoroughly reviewed. The separating frequency between the woofer and low- to mid-range unit has been set at 220 Hz. Thanks to this relatively low separating frequency, the bass is particularly powerful between 50 and 100 Hz. This is accompanied, however, by a reduction in impedance in this range of frequencies. There is compensation for the increased impedance in the woofer (KN 27 mH, 330 µF) which prevents this low impedance curve, but this also reduces the bass output level at 80 Hz by around 3 dB (red line below 100 Hz). This can be a great advantage in rooms where the bass output level is boosted excessively by resonance. Where the output level is more important and a reduction in nominal impedance at 80 Hz to 4 ohms is acceptable, the impedance compensation is simply deactivated to produce the higher frequency graph. In this way, the ATLAS COMPACT MK V offers a tangible advantage in that the bass output level can be trimmed to suit the listening room.

The broad chamfers in the upper part of the baffle give the cabinet a slimmer appearance while, at the same time, avoiding the build-up of corner reflection in the sensitive mid- and high-ranges.

The ATLAS COMPACT MK V is a very dynamic speaker with powerful 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.

Construction

Inside the large subwoofer cabinet there is a separate chamber that houses the low- to midrange unit. The tweeter and mid-range driver are also mounted in this cabinet.

To achieve the broad bevel on the upper third of the front panel, the sides of the low- to mid-range cabinet are doubled-up. Three 8 mm holes will have to be drilled in the rear wall of the low- to mid-range chamber for the cables. These must be well sealed off after the cables have been positioned.

The two round openings in the rear wall are for mounting the bass reflex tubes while the rectangular one is for the terminals. The frequency crossover unit is mounted on the wall behind the bass cut-out.

Inner damping

Two mats of damping material are pushed into the low- to mid-range cabinet.The remaining 10 mats are evenly distributed around the woofer chamber.
