As a result of this choice of drivers and the linear frequency response, it is ideally suited as a complementary centre speaker in conjunction with the VOX 253 MTI or TOPAS, for example, to produce a high-end home theatre system. As already seen in the ARIA 2, the magnetostat is positioned in the middle of the slim-line baffle and is flanked by the two titanium mid-bass units.
In contrast to centre speakers featuring a genuine D´Appolito arrangement, the ARIA 2 MHT CENTER is well suited to horizontal positioning e.g. above or below the television set, because it does not have anything like the same beaming effect. The sophisticated 2.5-band crossover circuitry is responsible for this feature. The crossover separates one of the two mid-bass units at 1800 Hz while the second is not separated until 4500 Hz is reached, to leave the higher frequencies to the magnetostat.
This deliberate individual treatment of the two TI 100 8 Ohm prevents noticeable directivity which, in a vertically placed D´Appolito arrangement, would be intentional but in a horizontally placed centre speaker must be avoided at all costs to ensure that all the seating positions in the home theatre are treated to the same volume levels.
All the cabinet panels are cut from 16 mm chipboard or medium density fibreboard, butt-jointed and glued. After that, the openings for the driver and terminals are cut out and any necessary recesses cut. The chamfer on the outer baffle can be made either before the cabinet is glued together or afterwards.
Since the cabinets are relatively small, it is hardly possible to mount the crossover inside the housing. The PCB can, however, simply be wrapped in damping material and placed inside the speaker if the rear wall is not removable.
