As I continue to upgrade into this new world of surround etc., at least for me, this board provides invaluable information to help me make new decisions. I welcome your thoughts and opinions on this question. I currently am using an old pair of direct radiating speakers as surrounds, and am going to upgrade, but to what type of speaker, not brand.

For dvd viewing in surround, we currently do 50% music concerts / 50% movies. I have a 400 sq. ft. room with a 20 ft. ceiling.

Would you use direct, bi, or di??
