Interesting article on building a massive sound system using "vintage" gear:
"The stacks in question are the seven 3.5-meter-tall speaker stacks that make up a monster, 50,000-watt sound system called Despacio. It was designed by LCD Soundsystem frontman James Murphy, along with legendary audio engineer John Klett and mashup masters 2ManyDJs (David and his brother Stephen Dewaele). After two years of development, Despacio made its debut over three nights in Manchester's New Century Hall in July. In December, the team is bringing the ten-tonne system to London's Hammersmith Town Hall."
