Hello, just set up new 5.1 system (onkyo 707 receiver, rti a7 fronts, csi a4 center, fxi a4 surrounds) and after reading about the receiver's front high and wide capabilities i have a quick question... for the front wide speakers i am curious if the best option would be like a bookshelf speaker or if maybe another set of bipole/dipole speakers would work best (probably set to bipole mode for more direct sound)... this is mainly a theoretical question as i am aware many people will recommend a traditional 7.1 setup and I am also aware that room considerations come into play... Just curious what people think
