What is missing here is:
1-How are these being used?
2-How many people will be present?
3-Is this going to be used only in my home?

For home use or gatherings of 50 people or less, I really feel the Logitech Z2300 at cost of $99 (Internet) will perform extremely well.

Two satellite speakers – very light – 5 inches tall. One sub – 8 inches.
You can control the amount of power (Volume) coming from the sub and satellites separately.

Circuit City I asking $155 and I was fortunate to buy mine at $69.
