Hi,
I would look at the speakers recommended by soundsgreat (see, we don't have to always disagree ) over Telome.
Finally something to look forward to in the future aswell

!!
Only 6.5 Inches speakers for Sub do not do any justice to bass .....a low priced JBL even has 8 inch speaker ....see if any package with 12 inchs sub is available!
Hemant,please read my post again

! its not a single 6.5" thats put to use ! I will not confuse or bore people with too techy stuff !! But you can take this info as a thumb rule !
Multiple small drivers performance is always better then a single big dia driver ! The reason is,in a big dia speaker the voice coil and the cone and such are designed for a certain parameter which it is intended to meet ! same goes to a small size dia driver !
So for example the JBL 8 " which you mention may have the capability to push X amount of Air,where as the 6.5" will push X minus lets say 25% (or if 8" is 100 the 6.5" will be 75 ) !!
Now this holds true if you have two different products where one uses a single 8" and the other uses a single 6.5" !! but if the a product uses multiple 6.5" what happens ? you do the simple math

!!
In the above example if you do the math, 4 numbers of 6.5" with a single unit capable of reproducing 75% of the 8" will obviously push more Air then a single 8" doesn't it ??
Now coming to the query by jayad, See in the list that you've put my personal suggestions is as follows,choice in the order as they appear !
1)ELAC - 59k ( 50 series I presume )
2)SKF4700 - (230W) SL107 - 38k (Sl 107 is the weakest link )
3)QAcoustic 1010i - 54k (overall balanced for movies but not for music)
4)PureAcoustic 799 - 45k (same as above but bit more aggressive or forward sound )
As with the AVR I'd personally say 465 as it sounds a tad bit better for music then Onkyo !
Regards.
