Summary: Beats my Logitech X-530's by a long shot even though these are less than half of them. Incredible bass response for just a 4" subwoofer; I couldn't be more impressed from its small form factor (TWSS). Brilliant, clear vocals and sharp highs is where it leaves the Logitech's in the dust. I can crank these up to about as loud as I would ever hope; without them distorting which you would not expect from just 17W speakers. I also love the slender design of these speakers.
Summary: I really enjoy this speaker system. The sound is clean and the basses are as deep as one wants thanks to the bass volume control. I had been using the Hercules 2.1 speaker system, then I had the chance to sell it to a friend and by this new one. I must say that Hercules is never disappointing.
Summary: Out of the box the front right channel doesn't work. I've not got a replacement yet, but if there's not something more fundamentally broken than the output on that one channel then this is a tinny, bass free experience. If a working version is better I'll post a better review (but I'll not buy Hercules again, I am incredibly unforgiving of a single not working out of the box experience).
Summary: I have gone three sets of Logitech speakers in the last 6 months!!! From a slight bang busting a sat from a blown sub to a faulty plug. Ridiculous waste of my time and effort and luckily Amazon replaced them each time. I got fed up and saw these. Boy how pleased I was when they arrived. Same price but just look so much neater being so tall and good looking. Sound quality is as good if not better than the Logitech.
