I'm after a speaker setup for my office. I'm midway into negotiations to purchase a set of Tannoy R3's which will do fine as stereo fronts. Now, I want the centre and surrounds to be as unobtrusive as possible. If I got Gallo balls for these 3 speakers, would it work? My main thing is stereo music so that will be fine but what when I put on a SACD or play my Xbox in 5.1? Do these ball absolutely need a sub or can they stand up as centre and surrounds? Opinions/ experiences please? Also, how much am I likely to pay for 3 secondhand gallos?
