Summary: These things are really, really good. I'd rate their sound above the Z-5500, and above the more recent THX sets.
They have plenty of power, and are reasonably articulate. No, they're not Hi-Fi, and won't compete with a good KEF speaker system paired with a reasonable amplifier.
Pros: Sound quality, bass quantity,
Cons: Reliability, controller, bass quantity can be overwhelming
Excerpt: One system that offers similarly impressive sound and that has a much lower price tag is the Logitech Z-560. Currently the lowest-priced four-channel THX-certified computer speaker on the market, it's the first system we've seen that beats the Klipsch ProMedia 4.1 at its own game.
Conclusion: As much as I praised this system in the review, of course there are better systems out there…if you pay the price! However, for the meagre (yeah I know its not exactly meagre) price tag of AU$499 (Available from PC's Australia in NSW for $394), these speakers provide superb sound in all...
