These speakers have been designed with Denon Hi-Fi craftsmanship and European Sound engineering. For best performance, a high quality 12 cm woofer / midrange chassis has been combined with a high definition tweeter and a crossover network with selected components to reproduces the smoothness of natural sound. They perfectly complement the RCD-M41 or RCD-M41DAB within the famous D-M41 / D-M41DAB HiFi System with CD and Bluetooth.
