Characteristics and sound properties
The ARIA 2 is a small-sized 2-band shelf-top speaker system that uses two TI 100 8 Ohm high-end mid-bass units and the G 20 SC 8 Ohm dome tweeter. The unit is equally well suited to life as a satellite in a straightforward stereo system or for use in a multichannel set-up. It can be combined with larger speakers such as the VOX 200 where it takes over the centre or effect role or a full set of them can be used to cover all channels. The lower limiting frequency is at 75 Hz, i.e. deep-bass should be left to an active subwoofer and the satellites will need protecting with a high-pass section or, in multichannel systems, they should be run in small mode.
If the speakers are positioned right by the wall or in a shelving unit, the bass reflex tube will be partly damped or completely stifled, which can compensate for excessively boosted bass.
Extract from HobbyHiFi
"Verdict: By making the universally applicable Aria 2 available, VISATON has enriched the existence of DIY speaker builders by a considerable amount. Even with a stand-alone compact speaker, the Aria 2 puts on a remarkably good show but in conjunction with a suitable bass driver it will wipe the board. This makes it eminently suitable for a step-by-step approach. A user could start by building a couple of Aria 2's, later on add a subwoofer and, after that, add a third Aria 2 as a centre speaker to make an entry into the world of surround systems a suitable Aria dipole speaker for the surround channels is also to be found in the VISATON catalogue."

CONSTRUCTION
The cabinet body uses 16 mm boards. First of all, cut the holes in the boards and apply the bevels. This can be done using an electric jigsaw or hand-held circular saw set to the required angle. Once the cabinet has been completed, apply the milling work for the loudspeaker. Finally, fit the cones.
Since the cabinets are relatively small, it is hardly possible to mount the crossover inside the housing. It can, however, simply be wrapped in damping material and placed inside the speaker if the rear wall is not removable.
Inner damping
The damping material is loosely arranged in the cabinet.
