The DM 604 is a free standing monitor created for exceptional performance across the whole range of listening requirements. ● It is a three way monitor with a dedicated Kevlar® mid-range driver, two Cobex bass drivers and a tunable port plug. ● The Kevlar® cone is housed within its own enclosure in the speaker cabinet and is restricted exclusively to mid-range frequencies. This prevents the cone from moving to bass frequencies, cutting down on harmonic distortion caused by unwanted cone movement. ● The bass is handled by two Cobex® cone drivers and is simply stunning. Doubling the bass drivers, dramatically improves the power handling and efficiency of the speaker and delivers far greater bass extension. T echnical highlights Kevlar®: B&W developed and patented the method of using Kevlar® for loudspeaker cones to reduce unwanted standing waves. DuPont originally created Kevlar® for use in bulletproof vests.
