We demonstrate order of magnitude coherent control of the total transmission through a disordered slab by shaping the wavefront of the input light. To understand the effect of finite illumination area on the maximum values of total transmission, we develop a model based on random matrix theory that reveals the role of long-range correlations. Predictions are confirmed by numerical simulations and shed light on our experimental results.
