Hi, i'm writing from Italy so excuse my orrible english. I'm looking for a good set of surround speaker. I need to update my classic stereo hifi. (Speakers KEF pre-amplifier Onkyo, final Proton....) Because of the good quality of the components already existing, i need a good set of speakers, but spending less of 500$. I decided for the BOSE set VCS-30 Series II.... What's your opinion???? I need also an opinion about the rear central channel for 6.1 surround... what kind of speaker is needed for this position? An other central speaker (like the front central)?
