B&W DM640 floorstanding speakers takes its design and performance from the renowned 800 series. Its unique design uses a completely isolated Kevlar midrange drive unit in its own enclosure for detailed and accurate sound. The tweeter features a magnetic fluid for cooling and to maintain accuracy under load. Low frequencies are handled by dual 200mm woofers. The cabinets are in generally good condition with some corner damage and light scratches. All drivers are in good condition. The tweeter surrounds have some odd spots, but would not clean off. Nothing that affects performance. The speaker play beautifully and sound great.
