how many/what size registers are needed?

I am putting about 650 cfm (1.5 ton, 3 speed variable air handler) into a 600 sf room (half shaded building, new construction w good insulation). Can someone tell me how many 4" x 12" floor registers this would require? I am also hoping to keep the noise levels minimal.
Many thanks!
