The R400b is just 14 inches high but with twin bass drivers and 500 Watts of power, it’s made for serious home theatre systems.
The R400b’s reinforced and braced cabinet houses twin 9 inches LF drivers powered by two 250 Watts class-D amplifiers. The drivers are mounted in a ‘force-cancelling’ arrangement for fast, powerful bass.
