Surround Setup advice (Speaker + Receiver)

[alrha]

it's funny because i actually wonder if i would even notice the difference sometimes between speakers. i just want to sit down and watch a movie and be blown away by the audio feeling like i'm really there (the way it sounds at the in store demonstrations).
I guess i will stick with the ML Dynamo rather than the supercube.

the nanosats prestige and the nanoCC only go down to 100Hz compared to the 70Hz of the Omnisats. is this a big difference that would be noticeable? or would the ML Dynamo make up for it? Also, considering that I am going for a 7.1, would that make the nanosat prestige sufficient as the additional speakers will make up for their smaller size? or would the two additional speakers only really work for effects and as such the sound may still not be enough?

Sorry for all the questions - but i guess that is the best way to learn.
