Thank you both for your comments, budget is low at present at around £300 (don't laugh), but this is for a used speakers/sub, and will be much better than current Samsung set, as stated this is new to me and I want to start at a more basic level than I'm sure you or most on this forum, I will then build and upgrade from this as time goes on and I have a better understanding. Room size is approx 22' x 11', tv in corner of room. The reason I considered the KHT1505 (HTS7001 speakers and C4 sub), is because I liked the compact speaker size.
