It's not hard to see the appeal of active speakers. With built-in amplifiers, each one dedicated to an individual driver, the design delivers greater sonic control and definition - and can be run from a simple preamplifier or even a network player with its own volume control. ATC has been building active speakers for many years, for use in both the studio and the home - and the compact SCM20ASL model, handcrafted throughout, is the perfect partner for today's streaming solutions. Plus it delivers jaw-dropping, spine-tingling sound.
