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.
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: 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.
Summary: I bought these after having selected a set of Logitech Z506. They were OK (nothing special in my mind), but stopped working two days after installation. Logitech didn't quibble, but I had to send them back. So, after much agonising, I decided to buy these Hercules speakers instead.
