Logitech X-530
Belonging to the same family as the 2.1 X-230 we tested earlier, the X-530 is essentially the same kit in a five-channel version.
The satellites again use the "Frequency Directed Dual Driver" technology, the goal of which is to eliminate lobes of interference between transducers while providing a larger membrane surface for reproducing the midrange frequencies - the weak suit of many speakers that put design uppermost. The idea is not really new: Filter the two vertically-arranged loudspeakers differently in order to limit interference between transducers. But it's a good idea!
