A few questions to the OP:
(1) how big is his room? Do you understand how large La Scalas are?
(2) do you really want to spend $12K on speakers for your kid (assuming new)? If so, congratulations on your deep pockets and generosity.
(3) if his primary desire is loudness (assume he is going to listen primarily to rock or club music), steer him toward Klipsch Heresy, JBL L100 or vintage Cerwin Vega speakers.
