Anyone have any experience with both of these speakers sets? Or know of a better set for under $400?

I have a Onkyo TX-SR603X AV Reciever, Samsung LN52A650 TV and a PS3 in a room that is11 feet by 32 but I will only be concered about the sound in a '11X'11 section. Yes I will have the LCR and TV on the end wall and thus 21 feet of open space behind the rear speakers.

In a year or so I plan on spending about 2K$ upgrading my AV reciever and speakers but for now I want something that sound better than a Sparkomatic car speaker taped into a card board box with foam in it for a center speaker, a $5 second hand pair of Optimus STS 620 & a $5 second hand pair of Sony SS MB105 for rear.
