Which has better bass?

[Jamiehutch]

Which speakers have better bass: Logitech Z533 or Logitech Z333? I will be using them for gaming but mostly music on my PC. If neither of these are there any better alternatives for sound quality with a powerful sub for under £100?

The sub in the Z533 is a 30W while the one in the Z333 is a 24W

Also the Z533 Sub enclosure is bigger - So the Z533 should have better and deeper bass
