"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."
