How many speakers did you use and what type?

The usual configuration consisted of sixteen 1x15" full-range reflex cabinets (20hz to as high as they'd go) - eight 1x10"(200hz to as high as they'd go) and sixteen 075 tweeters (5Khz upward). All drivers were JBL. Sometimes at larger venues such as the Rainbow, Finsbury Park and Hammersmith Odeon, twenty-four 1x15"s would be used. The amplifiers were Turner A500s and A300s and the total output of the standard sixteen cabinet rig would be no more than 3,500KW.

The system looked immaculate with all the speaker cabinets matching and covered in black vinyl with aluminium strips round the edges and this also suited the theatrical nature of the shows. The first mixer consisted of 12 channels only but was soon upgraded to 24. Believe it or not the echo facility was a Watkins Copy Cat tape-loop machine and that was the only sound-effect we used. At the beginning of the Ziggy touring period there were no on-stage monitors but with the wall of sound concept the band could hear the mix very well from their stage positions.
