Hello

i m thinking to buy a 5.1 audio system for my not very big living room, i have been browsing the sony website, and found the above 2 set of audio compact systems, could you give me some advice about these 2 systems? the specification for these 2 systems are very much the same,what is the RMS for the HTIB DPLII 5.1? the 2nd system is bass reflex design speaker, what is bass reflex design, is it important? when buying amplifier and speakers, what to look at to determine its quality?

your advise is appreciated.
