hi guys looking for some advice for my brother who is finally moving into the home theater realm. i already have boston acoustics, and my knowledge of jbl is pretty limited. his friend has some older jbl center and surrounds, my brother will be adding a newer pair of bookshelves for the mains. the model is a cs200 bk center and surrounds, are they decent, his friend is not asking a lot for them, the amount would be silly if i had to convert it into dollars. thanks in advance.
