The CRM-2 is a 400 Watt, powerhouse that delivers the clarity and output of a 6-foot tall speaker–yet stands about 8-inches tall. Sunfire’s unique and patented High Back-emf design lets extremely loud sound take place within a very small cabinet. The Duos feature a pair of our 4.5" side-firing woofers that deliver an incredible 115dB of output from the smallest cabinet.
