Those speakers are loud enough to impress you and loud enough that when your neighbors go out you can turn your room into a battle zone with a little volume. I wait for these times where I live. I like the sound of a Thompson sub machine gun when it's loud enough to vibrate the desk and you with it. Alot of logitech speakers have came down alot in price. I have owned my Z-640's for about 2 yrs and I have had zero issues with them. The X-530 are the newest version of the 640's according to reviews anyway. The sub is loud enough you will feel it easily. Good luck with your purchase.
BTW going the home theatre route is great if you have the space and the money. YOu will be happy with those speakers, THe Z-640's are great to if you can find a set..
