Dieci component systems let you realize a high quality audio system with the utmost in simplicity. The woofers employ the exclusive V-cone® profile for amazing off-axis response and detailed mid-high range. The TPU (Thermoplastic polyurethane) surround ensures linearity and reduction of unwanted resonance, even at high excursion. High-performance materials, such as the neodymium motor assembly and the PEI membrane, ensure an extended high frequency range. The passive filters are found directly on the supplied connection cables, along with a rich array of accessories increasing the install-friendliness and installation time.
