The LaVoce FSN041.00 is a superb 4" full-range driver that features a rising response, which is ideal for line arrays. The low resonant frequency of 110 Hz, gives this driver the ability to crossover very low, and mate to a subwoofer easily. The gasket on this driver allows it to be rear mounted easily, providing additional installation flexibility. To add to the versatility of this driver, the cone has been treated to be waterproof, making it ideal for outdoor cabinets.
